+Linker-Generated Arrays
+=======================
+
+A linker list is constructed by grouping together linker input
+sections, each containing one entry of the list. Each input section
+contains a constant initialized variable which holds the entry's
+content. Linker list input sections are constructed from the list
+and entry names, plus a prefix which allows grouping all lists
+together. Assuming _list and _entry are the list and entry names,
+then the corresponding input section name is
+
+::
+
+ .u_boot_list_ + 2_ + @_list + _2_ + @_entry
+
+and the C variable name is
+
+::
+
+ _u_boot_list + _2_ + @_list + _2_ + @_entry
+
+This ensures uniqueness for both input section and C variable name.
+
+Note that the names differ only in the first character, "." for the
+section and "_" for the variable, so that the linker cannot confuse
+section and symbol names. From now on, both names will be referred
+to as
+
+::
+
+ %u_boot_list_ + 2_ + @_list + _2_ + @_entry
+
+Entry variables need never be referred to directly.
+
+The naming scheme for input sections allows grouping all linker lists
+into a single linker output section and grouping all entries for a
+single list.
+
+Note the two '_2_' constant components in the names: their presence
+allows putting a start and end symbols around a list, by mapping
+these symbols to sections names with components "1" (before) and
+"3" (after) instead of "2" (within).
+Start and end symbols for a list can generally be defined as
+
+::
+
+ %u_boot_list_2_ + @_list + _1_...
+ %u_boot_list_2_ + @_list + _3_...
+
+Start and end symbols for the whole of the linker lists area can be
+defined as
+
+::
+
+ %u_boot_list_1_...
+ %u_boot_list_3_...
+
+Here is an example of the sorted sections which result from a list
+"array" made up of three entries : "first", "second" and "third",
+iterated at least once.
+
+::
+
+ .u_boot_list_2_array_1
+ .u_boot_list_2_array_2_first
+ .u_boot_list_2_array_2_second
+ .u_boot_list_2_array_2_third
+ .u_boot_list_2_array_3
+
+If lists must be divided into sublists (e.g. for iterating only on
+part of a list), one can simply give the list a name of the form
+'outer_2_inner', where 'outer' is the global list name and 'inner'
+is the sub-list name. Iterators for the whole list should use the
+global list name ("outer"); iterators for only a sub-list should use
+the full sub-list name ("outer_2_inner").
+
+Here is an example of the sections generated from a global list
+named "drivers", two sub-lists named "i2c" and "pci", and iterators
+defined for the whole list and each sub-list:
+
+::
+
+ %u_boot_list_2_drivers_1
+ %u_boot_list_2_drivers_2_i2c_1
+ %u_boot_list_2_drivers_2_i2c_2_first
+ %u_boot_list_2_drivers_2_i2c_2_first
+ %u_boot_list_2_drivers_2_i2c_2_second
+ %u_boot_list_2_drivers_2_i2c_2_third
+ %u_boot_list_2_drivers_2_i2c_3
+ %u_boot_list_2_drivers_2_pci_1
+ %u_boot_list_2_drivers_2_pci_2_first
+ %u_boot_list_2_drivers_2_pci_2_second
+ %u_boot_list_2_drivers_2_pci_2_third
+ %u_boot_list_2_drivers_2_pci_3

+ scalable figure and image handling
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ Sphinx extension which implements scalable image handling.
+
+ :copyright: Copyright (C) 2016 Markus Heiser
+ :license: GPL Version 2, June 1991 see Linux/COPYING for details.
+
+ The build for image formats depend on image's source format and output's
+ destination format. This extension implement methods to simplify image
+ handling from the author's POV. Directives like ``kernel-figure`` implement
+ methods *to* always get the best output-format even if some tools are not
+ installed. For more details take a look at ``convert_image(...)`` which is
+ the core of all conversions.
+
+ * ``.. kernel-image``: for image handling / a ``.. image::`` replacement
+
+ * ``.. kernel-figure``: for figure handling / a ``.. figure::`` replacement
+
+ * ``.. kernel-render``: for render markup / a concept to embed *render*
+ markups (or languages). Supported markups (see ``RENDER_MARKUP_EXT``)
+
+ - ``DOT``: render embedded Graphviz's **DOC**
+ - ``SVG``: render embedded Scalable Vector Graphics (**SVG**)
+ - ... *developable*
+
+ Used tools:
+
+ * ``dot(1)``: Graphviz (http://www.graphviz.org). If Graphviz is not
+ available, the DOT language is inserted as literal-block.
+
+ * SVG to PDF: To generate PDF, you need at least one of this tools:
+
+ - ``convert(1)``: ImageMagick (https://www.imagemagick.org)
+
+ List of customizations:
+
+ * generate PDF from SVG / used by PDF (LaTeX) builder
+
+ * generate SVG (html-builder) and PDF (latex-builder) from DOT files.
+ DOT: see http://www.graphviz.org/content/dot-language

+=head1 DESCRIPTION
+
+Convert a C header or source file (C_FILE), into a ReStructured Text
+included via ..parsed-literal block with cross-references for the
+documentation files that describe the API. It accepts an optional
+EXCEPTIONS_FILE with describes what elements will be either ignored or
+be pointed to a non-default reference.
+
+The output is written at the (OUT_FILE).
+
+It is capable of identifying defines, functions, structs, typedefs,
+enums and enum symbols and create cross-references for all of them.
+It is also capable of distinguish #define used for specifying a Linux
+ioctl.
+
+The EXCEPTIONS_FILE contain two rules to allow ignoring a symbol or
+to replace the default references by a custom one.
+
+Please read Documentation/doc-guide/parse-headers.rst at the Kernel's
+tree for more details.

+ flat-table
+ ~~~~~~~~~~
+
+ Implementation of the ``flat-table`` reST-directive.
+
+ :copyright: Copyright (C) 2016 Markus Heiser
+ :license: GPL Version 2, June 1991 see linux/COPYING for details.
+
+ The ``flat-table`` (:py:class:`FlatTable`) is a double-stage list similar to
+ the ``list-table`` with some additional features:
+
+ * *column-span*: with the role ``cspan`` a cell can be extended through
+ additional columns
+
+ * *row-span*: with the role ``rspan`` a cell can be extended through
+ additional rows
+
+ * *auto span* rightmost cell of a table row over the missing cells on the
+ right side of that table-row. With Option ``:fill-cells:`` this behavior
+ can changed from *auto span* to *auto fill*, which automaticly inserts
+ (empty) cells instead of spanning the last cell.
+
+ Options:
+
+ * header-rows: [int] count of header rows
+ * stub-columns: [int] count of stub columns
+ * widths: [[int] [int] ... ] widths of columns
+ * fill-cells: instead of autospann missing cells, insert missing cells
+
+ roles:
+
+ * cspan: [int] additionale columns (*morecols*)
+ * rspan: [int] additionale rows (*morerows*)

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License along
- with this program; if not, write to the Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) year name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.

+ R: Designated reviewer: FullName <address@domain>
+ These reviewers should be CCed on patches.
+ L: Mailing list that is relevant to this area
+ W: Web-page with status/info
+ Q: Patchwork web based patch tracking system site
+ T: SCM tree type and location.
+ Type is one of: git, hg, quilt, stgit, topgit
+ S: Status, one of the following:
+ Supported: Someone is actually paid to look after this.
+ Maintained: Someone actually looks after it.
+ Odd Fixes: It has a maintainer but they don't have time to do
+ much other than throw the odd patch in. See below..
+ Orphan: No current maintainer [but maybe you could take the
+ role as you write your new code].
+ Obsolete: Old code. Something tagged obsolete generally means
+ it has been replaced by a better system and you
+ should be using that.
+ F: Files and directories with wildcard patterns.
+ A trailing slash includes all files and subdirectory files.
+ F: drivers/net/ all files in and below drivers/net
+ F: drivers/net/* all files in drivers/net, but not below
+ F: */net/* all files in "any top level directory"/net
+ One pattern per line. Multiple F: lines acceptable.
+ N: Files and directories with regex patterns.
+ N: [^a-z]tegra all files whose path contains the word tegra
+ One pattern per line. Multiple N: lines acceptable.
+ scripts/get_maintainer.pl has different behavior for files that
+ match F: pattern and matches of N: patterns. By default,
+ get_maintainer will not look at git log history when an F: pattern
+ match occurs. When an N: match occurs, git log history is used
+ to also notify the people that have git commit signatures.
+ X: Files and directories that are NOT maintained, same rules as F:
+ Files exclusions are tested before file matches.
+ Can be useful for excluding a specific subdirectory, for instance:
+ F: net/
+ X: net/ipv6/
+ matches all files in and below net excluding net/ipv6/
+ K: Keyword perl extended regex pattern to match content in a
+ patch or file. For instance:
+ K: of_get_profile
+ matches patches or files that contain "of_get_profile"
+ K: \b(printk|pr_(info|err))\b
+ matches patches or files that contain one or more of the words
+ printk, pr_info or pr_err
+ One regex pattern per line. Multiple K: lines acceptable.
+
+Note: For the hard of thinking, this list is meant to remain in alphabetical
+order. If you could add yourselves to it in alphabetical order that would be
+so much easier [Ed]

+# their own directory. If in some directory we have a dependency on
+# a file in another dir (which doesn't happen often, but it's often
+# unavoidable when linking the built-in.o targets which finally
+# turn into vmlinux), we will call a sub make in that other dir, and
+# after that we are sure that everything which is in that other dir
+# is now up to date.
+#
+# The only cases where we need to modify files which have global
+# effects are thus separated out and done before the recursive
+# descending is started. They are now explicitly listed as the
+# prepare rule.
+
+# We use U_BOOT_DATE and U_BOOT_TIME to record u-boot build timestamp.

+Summary:
+========
+
+This directory contains the source code for U-Boot, a boot loader for
+Embedded boards based on PowerPC, ARM, MIPS and several other
+processors, which can be installed in a boot ROM and used to
+initialize and test the hardware or to download and run application
+code.
+
+The development of U-Boot is closely related to Linux: some parts of
+the source code originate in the Linux source tree, we have some
+header files in common, and special provision has been made to
+support booting of Linux images.
+
+Some attention has been paid to make this software easily
+configurable and extendable. For instance, all monitor commands are
+implemented with the same call interface, so that it's very easy to
+add new commands. Also, instead of permanently adding rarely used
+code (for instance hardware test utilities) to the monitor, you can
+load and run it dynamically.
+
+
+Status:
+=======
+
+In general, all boards for which a configuration option exists in the
+Makefile have been tested to some extent and can be considered
+"working". In fact, many of them are used in production systems.
+
+In case of problems see the CHANGELOG file to find out who contributed
+the specific port. In addition, there are various MAINTAINERS files
+scattered throughout the U-Boot source identifying the people or
+companies responsible for various boards and subsystems.
+
+Note: As of August, 2010, there is no longer a CHANGELOG file in the
+actual U-Boot source tree; however, it can be created dynamically
+from the Git log using:
+
+ make CHANGELOG

+
+Software Configuration:
+=======================
+
+Configuration is usually done using C preprocessor defines; the
+rationale behind that is to avoid dead code whenever possible.
+
+There are two classes of configuration variables:
+
+* Configuration _OPTIONS_:
+ These are selectable by the user and have names beginning with
+ "CONFIG_".
+
+* Configuration _SETTINGS_:
+ These depend on the hardware etc. and should not be meddled with if
+ you don't know what you're doing; they have names beginning with
+ "CONFIG_SYS_".
+
+Previously, all configuration was done by hand, which involved creating
+symbolic links and editing configuration files manually. More recently,
+U-Boot has added the Kbuild infrastructure used by the Linux kernel,
+allowing you to use the "make menuconfig" command to configure your
+build.
+
+
+Selection of Processor Architecture and Board Type:
+---------------------------------------------------
+
+For all supported boards there are ready-to-use default
+configurations available; just type "make <board_name>_defconfig".
+
+Example: For a TQM823L module type:
+
+ cd u-boot
+ make TQM823L_defconfig
+
+Note: If you're looking for the default configuration file for a board
+you're sure used to be there but is now missing, check the file
+doc/README.scrapyard for a list of no longer supported boards.
+
+Sandbox Environment:
+--------------------
+
+U-Boot can be built natively to run on a Linux host using the 'sandbox'
+board. This allows feature development which is not board- or architecture-
+specific to be undertaken on a native platform. The sandbox is also used to
+run some of U-Boot's tests.
+
+See board/sandbox/README.sandbox for more details.
+
+
+Board Initialisation Flow:
+--------------------------
+
+This is the intended start-up flow for boards. This should apply for both
+SPL and U-Boot proper (i.e. they both follow the same rules).
+
+Note: "SPL" stands for "Secondary Program Loader," which is explained in
+more detail later in this file.
+
+At present, SPL mostly uses a separate code path, but the function names
+and roles of each function are the same. Some boards or architectures
+may not conform to this. At least most ARM boards which use
+CONFIG_SPL_FRAMEWORK conform to this.
+
+Execution typically starts with an architecture-specific (and possibly
+CPU-specific) start.S file, such as:
+
+ - arch/arm/cpu/armv7/start.S
+ - arch/powerpc/cpu/mpc83xx/start.S
+ - arch/mips/cpu/start.S
+
+and so on. From there, three functions are called; the purpose and
+limitations of each of these functions are described below.
+
+lowlevel_init():
+ - purpose: essential init to permit execution to reach board_init_f()
+ - no global_data or BSS
+ - there is no stack (ARMv7 may have one but it will soon be removed)
+ - must not set up SDRAM or use console
+ - must only do the bare minimum to allow execution to continue to
+ board_init_f()
+ - this is almost never needed
+ - return normally from this function
+
+board_init_f():
+ - purpose: set up the machine ready for running board_init_r():
+ i.e. SDRAM and serial UART
+ - global_data is available
+ - stack is in SRAM
+ - BSS is not available, so you cannot use global/static variables,
+ only stack variables and global_data
+
+ Non-SPL-specific notes:
+ - dram_init() is called to set up DRAM. If already done in SPL this
+ can do nothing
+
+ SPL-specific notes:
+ - you can override the entire board_init_f() function with your own
+ version as needed.
+ - preloader_console_init() can be called here in extremis
+ - should set up SDRAM, and anything needed to make the UART work
+ - these is no need to clear BSS, it will be done by crt0.S
+ - must return normally from this function (don't call board_init_r()
+ directly)
+
+Here the BSS is cleared. For SPL, if CONFIG_SPL_STACK_R is defined, then at
+this point the stack and global_data are relocated to below
+CONFIG_SPL_STACK_R_ADDR. For non-SPL, U-Boot is relocated to run at the top of
+memory.
+
+board_init_r():
+ - purpose: main execution, common code
+ - global_data is available
+ - SDRAM is available
+ - BSS is available, all static/global variables can be used
+ - execution eventually continues to main_loop()
+
+ Non-SPL-specific notes:
+ - U-Boot is relocated to the top of memory and is now running from
+ there.
+
+ SPL-specific notes:
+ - stack is optionally in SDRAM, if CONFIG_SPL_STACK_R is defined and
+ CONFIG_SPL_STACK_R_ADDR points into SDRAM
+ - preloader_console_init() can be called here - typically this is
+ done by selecting CONFIG_SPL_BOARD_INIT and then supplying a
+ spl_board_init() function containing this call
+ - loads U-Boot or (in falcon mode) Linux
+
+
+
+Configuration Options:
+----------------------
+
+Configuration depends on the combination of board and CPU type; all
+such information is kept in a configuration file
+"include/configs/<board_name>.h".
+
+Example: For a TQM823L module, all configuration settings are in
+"include/configs/TQM823L.h".
+
+
+Many of the options are named exactly as the corresponding Linux
+kernel configuration options. The intention is to make it easier to
+build a config tool - later.
+
+- ARM Platform Bus Type(CCI):
+ CoreLink Cache Coherent Interconnect (CCI) is ARM BUS which
+ provides full cache coherency between two clusters of multi-core
+ CPUs and I/O coherency for devices and I/O masters

+
+ Defined For SoC that has cache coherent interconnect
+ CCN-400
+

+
+ Defines one or two SoC revisions (low 8 bits of SVR)
+ for which the A004510 workaround should be applied.
+
+ The rest of SVR is either not relevant to the decision
+ of whether the erratum is present (e.g. p2040 versus
+ p2041) or is implied by the build target, which controls
+ whether CONFIG_SYS_FSL_ERRATUM_A004510 is set.
+
+ See Freescale App Note 4493 for more information about
+ this erratum.
+
+ CONFIG_A003399_NOR_WORKAROUND

+
+ CONFIG_SYS_FSL_SINGLE_SOURCE_CLK
+ Single Source Clock is clocking mode present in some of FSL SoC's.
+ In this mode, a single differential clock is used to supply
+ clocks to the sysclock, ddrclock and usbclock.
+
+ CONFIG_SYS_CPC_REINIT_F
+ This CONFIG is defined when the CPC is configured as SRAM at the
+ time of U-Boot entry and is required to be re-initialized.
+
+ CONFIG_DEEP_SLEEP
+ Indicates this SoC supports deep sleep feature. If deep sleep is
+ supported, core will start to execute uboot when wakes up.
+
+- Generic CPU options:
+ CONFIG_SYS_BIG_ENDIAN, CONFIG_SYS_LITTLE_ENDIAN
+
+ Defines the endianess of the CPU. Implementation of those
+ values is arch specific.

+
+- MIPS CPU options:
+ CONFIG_SYS_INIT_SP_OFFSET
+
+ Offset relative to CONFIG_SYS_SDRAM_BASE for initial stack
+ pointer. This is needed for the temporary stack before
+ relocation.
+
+ CONFIG_XWAY_SWAP_BYTES
+
+ Enable compilation of tools/xway-swap-bytes needed for Lantiq
+ XWAY SoCs for booting from NOR flash. The U-Boot image needs to
+ be swapped if a flash programmer is used.
+
+- ARM options:
+ CONFIG_SYS_EXCEPTION_VECTORS_HIGH
+
+ Select high exception vectors of the ARM core, e.g., do not
+ clear the V bit of the c1 register of CP15.
+
+ COUNTER_FREQUENCY
+ Generic timer clock source frequency.
+
+ COUNTER_FREQUENCY_REAL
+ Generic timer clock source frequency if the real clock is
+ different from COUNTER_FREQUENCY, and can only be determined
+ at run time.
+
+- Tegra SoC options:
+ CONFIG_TEGRA_SUPPORT_NON_SECURE
+
+ Support executing U-Boot in non-secure (NS) mode. Certain
+ impossible actions will be skipped if the CPU is in NS mode,
+ such as ARM architectural timer initialization.
+
+- Linux Kernel Interface:
+ CONFIG_CLOCKS_IN_MHZ
+
+ U-Boot stores all clock information in Hz
+ internally. For binary compatibility with older Linux
+ kernels (which expect the clocks passed in the
+ bd_info data to be in MHz) the environment variable
+ "clocks_in_mhz" can be defined so that U-Boot
+ converts clock data to MHZ before passing it to the
+ Linux kernel.
+ When CONFIG_CLOCKS_IN_MHZ is defined, a definition of
+ "clocks_in_mhz=1" is automatically included in the
+ default environment.
+
+ CONFIG_MEMSIZE_IN_BYTES [relevant for MIPS only]
+
+ When transferring memsize parameter to Linux, some versions
+ expect it to be in bytes, others in MB.
+ Define CONFIG_MEMSIZE_IN_BYTES to make it in bytes.
+
+ CONFIG_OF_LIBFDT
+
+ New kernel versions are expecting firmware settings to be
+ passed using flattened device trees (based on open firmware
+ concepts).
+
+ CONFIG_OF_LIBFDT
+ * New libfdt-based support
+ * Adds the "fdt" command
+ * The bootm command automatically updates the fdt
+
+ OF_TBCLK - The timebase frequency.
+ OF_STDOUT_PATH - The path to the console device
+
+ boards with QUICC Engines require OF_QE to set UCC MAC
+ addresses
+
+ CONFIG_OF_BOARD_SETUP
+
+ Board code has addition modification that it wants to make
+ to the flat device tree before handing it off to the kernel
+
+ CONFIG_OF_SYSTEM_SETUP
+
+ Other code has addition modification that it wants to make
+ to the flat device tree before handing it off to the kernel.
+ This causes ft_system_setup() to be called before booting
+ the kernel.
+
+ CONFIG_OF_IDE_FIXUP
+
+ U-Boot can detect if an IDE device is present or not.
+ If not, and this new config option is activated, U-Boot
+ removes the ATA node from the DTS before booting Linux,
+ so the Linux IDE driver does not probe the device and
+ crash. This is needed for buggy hardware (uc101) where
+ no pull down resistor is connected to the signal IDE5V_DD7.
+
+ CONFIG_MACH_TYPE [relevant for ARM only][mandatory]
+
+ This setting is mandatory for all boards that have only one
+ machine type and must be used to specify the machine type
+ number as it appears in the ARM machine registry
+ (see http://www.arm.linux.org.uk/developer/machines/).
+ Only boards that have multiple machine types supported
+ in a single configuration file and the machine type is
+ runtime discoverable, do not have to use this setting.
+
+- vxWorks boot parameters:
+
+ bootvx constructs a valid bootline using the following
+ environments variables: bootdev, bootfile, ipaddr, netmask,
+ serverip, gatewayip, hostname, othbootargs.
+ It loads the vxWorks image pointed bootfile.
+
+ Note: If a "bootargs" environment is defined, it will overwride
+ the defaults discussed just above.
+
+- Cache Configuration:
+ CONFIG_SYS_ICACHE_OFF - Do not enable instruction cache in U-Boot
+ CONFIG_SYS_DCACHE_OFF - Do not enable data cache in U-Boot
+ CONFIG_SYS_L2CACHE_OFF- Do not enable L2 cache in U-Boot
+
+- Cache Configuration for ARM:
+ CONFIG_SYS_L2_PL310 - Enable support for ARM PL310 L2 cache
+ controller
+ CONFIG_SYS_PL310_BASE - Physical base address of PL310
+ controller register space
+
+- Serial Ports:
+ CONFIG_PL010_SERIAL
+
+ Define this if you want support for Amba PrimeCell PL010 UARTs.
+
+ CONFIG_PL011_SERIAL
+
+ Define this if you want support for Amba PrimeCell PL011 UARTs.
+
+ CONFIG_PL011_CLOCK
+
+ If you have Amba PrimeCell PL011 UARTs, set this variable to
+ the clock speed of the UARTs.
+
+ CONFIG_PL01x_PORTS
+
+ If you have Amba PrimeCell PL010 or PL011 UARTs on your board,
+ define this to a list of base addresses for each (supported)
+ port. See e.g. include/configs/versatile.h
+
+ CONFIG_SERIAL_HW_FLOW_CONTROL
+
+ Define this variable to enable hw flow control in serial driver.
+ Current user of this option is drivers/serial/nsl16550.c driver
+
+- Console Baudrate:
+ CONFIG_BAUDRATE - in bps
+ Select one of the baudrates listed in
+ CONFIG_SYS_BAUDRATE_TABLE, see below.
+
+- Autoboot Command:
+ CONFIG_BOOTCOMMAND
+ Only needed when CONFIG_BOOTDELAY is enabled;
+ define a command string that is automatically executed
+ when no character is read on the console interface
+ within "Boot Delay" after reset.
+
+ CONFIG_RAMBOOT and CONFIG_NFSBOOT
+ The value of these goes into the environment as
+ "ramboot" and "nfsboot" respectively, and can be used
+ as a convenience, when switching between booting from
+ RAM and NFS.
+
+- Pre-Boot Commands:
+ CONFIG_PREBOOT
+
+ When this option is #defined, the existence of the
+ environment variable "preboot" will be checked
+ immediately before starting the CONFIG_BOOTDELAY
+ countdown and/or running the auto-boot command resp.
+ entering interactive mode.
+
+ This feature is especially useful when "preboot" is
+ automatically generated or modified. For an example
+ see the LWMON board specific code: here "preboot" is
+ modified when the user holds down a certain
+ combination of keys on the (special) keyboard when
+ booting the systems
+
+- Serial Download Echo Mode:
+ CONFIG_LOADS_ECHO
+ If defined to 1, all characters received during a
+ serial download (using the "loads" command) are
+ echoed back. This might be needed by some terminal
+ emulations (like "cu"), but may as well just take
+ time on others. This setting #define's the initial
+ value of the "loads_echo" environment variable.
+
+- Kgdb Serial Baudrate: (if CONFIG_CMD_KGDB is defined)
+ CONFIG_KGDB_BAUDRATE
+ Select one of the baudrates listed in
+ CONFIG_SYS_BAUDRATE_TABLE, see below.
+
+- Removal of commands
+ If no commands are needed to boot, you can disable
+ CONFIG_CMDLINE to remove them. In this case, the command line
+ will not be available, and when U-Boot wants to execute the
+ boot command (on start-up) it will call board_run_command()
+ instead. This can reduce image size significantly for very
+ simple boot procedures.
+
+- Regular expression support:
+ CONFIG_REGEX
+ If this variable is defined, U-Boot is linked against
+ the SLRE (Super Light Regular Expression) library,
+ which adds regex support to some commands, as for
+ example "env grep" and "setexpr".
+
+- Device tree:
+ CONFIG_OF_CONTROL
+ If this variable is defined, U-Boot will use a device tree
+ to configure its devices, instead of relying on statically
+ compiled #defines in the board file. This option is
+ experimental and only available on a few boards. The device
+ tree is available in the global data as gd->fdt_blob.
+
+ U-Boot needs to get its device tree from somewhere. This can
+ be done using one of the three options below:
+
+ CONFIG_OF_EMBED
+ If this variable is defined, U-Boot will embed a device tree
+ binary in its image. This device tree file should be in the
+ board directory and called <soc>-<board>.dts. The binary file
+ is then picked up in board_init_f() and made available through
+ the global data structure as gd->fdt_blob.
+
+ CONFIG_OF_SEPARATE
+ If this variable is defined, U-Boot will build a device tree
+ binary. It will be called u-boot.dtb. Architecture-specific
+ code will locate it at run-time. Generally this works by:
+
+ cat u-boot.bin u-boot.dtb >image.bin
+
+ and in fact, U-Boot does this for you, creating a file called
+ u-boot-dtb.bin which is useful in the common case. You can
+ still use the individual files if you need something more
+ exotic.
+
+ CONFIG_OF_BOARD
+ If this variable is defined, U-Boot will use the device tree
+ provided by the board at runtime instead of embedding one with
+ the image. Only boards defining board_fdt_blob_setup() support
+ this option (see include/fdtdec.h file).
+
+- Watchdog:
+ CONFIG_WATCHDOG
+ If this variable is defined, it enables watchdog
+ support for the SoC. There must be support in the SoC
+ specific code for a watchdog. For the 8xx
+ CPUs, the SIU Watchdog feature is enabled in the SYPCR
+ register. When supported for a specific SoC is
+ available, then no further board specific code should
+ be needed to use it.
+
+ CONFIG_HW_WATCHDOG
+ When using a watchdog circuitry external to the used
+ SoC, then define this variable and provide board
+ specific code for the "hw_watchdog_reset" function.
+
+ CONFIG_AT91_HW_WDT_TIMEOUT
+ specify the timeout in seconds. default 2 seconds.
+
+- Real-Time Clock:
+
+ When CONFIG_CMD_DATE is selected, the type of the RTC
+ has to be selected, too. Define exactly one of the
+ following options:
+
+ CONFIG_RTC_PCF8563 - use Philips PCF8563 RTC
+ CONFIG_RTC_MC13XXX - use MC13783 or MC13892 RTC
+ CONFIG_RTC_MC146818 - use MC146818 RTC
+ CONFIG_RTC_DS1307 - use Maxim, Inc. DS1307 RTC
+ CONFIG_RTC_DS1337 - use Maxim, Inc. DS1337 RTC
+ CONFIG_RTC_DS1338 - use Maxim, Inc. DS1338 RTC
+ CONFIG_RTC_DS1339 - use Maxim, Inc. DS1339 RTC
+ CONFIG_RTC_DS164x - use Dallas DS164x RTC
+ CONFIG_RTC_ISL1208 - use Intersil ISL1208 RTC
+ CONFIG_RTC_MAX6900 - use Maxim, Inc. MAX6900 RTC
+ CONFIG_RTC_DS1337_NOOSC - Turn off the OSC output for DS1337
+ CONFIG_SYS_RV3029_TCR - enable trickle charger on
+ RV3029 RTC.
+
+ Note that if the RTC uses I2C, then the I2C interface
+ must also be configured. See I2C Support, below.
+
+- GPIO Support:
+ CONFIG_PCA953X - use NXP's PCA953X series I2C GPIO
+
+ The CONFIG_SYS_I2C_PCA953X_WIDTH option specifies a list of
+ chip-ngpio pairs that tell the PCA953X driver the number of
+ pins supported by a particular chip.
+
+ Note that if the GPIO device uses I2C, then the I2C interface
+ must also be configured. See I2C Support, below.
+
+- I/O tracing:
+ When CONFIG_IO_TRACE is selected, U-Boot intercepts all I/O
+ accesses and can checksum them or write a list of them out
+ to memory. See the 'iotrace' command for details. This is
+ useful for testing device drivers since it can confirm that
+ the driver behaves the same way before and after a code
+ change. Currently this is supported on sandbox and arm. To
+ add support for your architecture, add '#include <iotrace.h>'
+ to the bottom of arch/<arch>/include/asm/io.h and test.
+
+ Example output from the 'iotrace stats' command is below.
+ Note that if the trace buffer is exhausted, the checksum will
+ still continue to operate.
+
+ iotrace is enabled
+ Start: 10000000 (buffer start address)
+ Size: 00010000 (buffer size)
+ Offset: 00000120 (current buffer offset)
+ Output: 10000120 (start + offset)
+ Count: 00000018 (number of trace records)
+ CRC32: 9526fb66 (CRC32 of all trace records)
+
+- Timestamp Support:
+
+ When CONFIG_TIMESTAMP is selected, the timestamp
+ (date and time) of an image is printed by image
+ commands like bootm or iminfo. This option is
+ automatically enabled when you select CONFIG_CMD_DATE .
+
+- Partition Labels (disklabels) Supported:
+ Zero or more of the following:
+ CONFIG_MAC_PARTITION Apple's MacOS partition table.
+ CONFIG_ISO_PARTITION ISO partition table, used on CDROM etc.
+ CONFIG_EFI_PARTITION GPT partition table, common when EFI is the
+ bootloader. Note 2TB partition limit; see
+ disk/part_efi.c
+ CONFIG_SCSI) you must configure support for at
+ least one non-MTD partition type as well.
+
+- IDE Reset method:
+ CONFIG_IDE_RESET_ROUTINE - this is defined in several
+ board configurations files but used nowhere!

+ CONFIG_IDE_RESET - is this is defined, IDE Reset will
+ be performed by calling the function
+ ide_set_reset(int reset)
+ which has to be defined in a board specific file
+
+- ATAPI Support:
+ CONFIG_ATAPI
+
+ Set this to enable ATAPI support.
+
+- LBA48 Support

+ Whithout these , LBA48 support uses 32bit variables and will 'only'
+ support disks up to 2.1TB.
+
+ CONFIG_SYS_64BIT_LBA:
+ When enabled, makes the IDE subsystem use 64bit sector addresses.
+ Default is 32bit.
+
+- SCSI Support:
+ CONFIG_SYS_SCSI_MAX_LUN [8], CONFIG_SYS_SCSI_MAX_SCSI_ID [7] and
+ CONFIG_SYS_SCSI_MAX_DEVICE [CONFIG_SYS_SCSI_MAX_SCSI_ID *
+ CONFIG_SYS_SCSI_MAX_LUN] can be adjusted to define the
+ maximum numbers of LUNs, SCSI ID's and target
+ devices.
+
+ The environment variable 'scsidevs' is set to the number of
+ SCSI devices found during the last scan.
+
+- NETWORK Support (PCI):

+ Support for Intel 8254x/8257x gigabit chips.
+
+ CONFIG_E1000_SPI
+ Utility code for direct access to the SPI bus on Intel 8257x.

+ If your system has 10/100 PHY only, it might not occur
+ wrong behavior. Because PHY usually return timeout or
+ useless data when polling gigabit status and gigabit
+ control registers. This behavior won't affect the
+ correctnessof 10/100 link speed update.
+

+ CONFIG_TPM_AUTH_SESSIONS
+ Define this to enable authorized functions in the TPM library.
+ Requires CONFIG_TPM and CONFIG_SHA1.
+
+- USB Support:
+ At the moment only the UHCI host controller is
+ supported (PIP405, MIP405); define
+ CONFIG_USB_UHCI to enable it.
+ define CONFIG_USB_KEYBOARD to enable the USB Keyboard
+ and define CONFIG_USB_STORAGE to enable the USB
+ storage devices.
+ Note:
+ Supported are USB Keyboards and USB Floppy drives
+ (TEAC FD-05PUB).
+
+ CONFIG_USB_EHCI_TXFIFO_THRESH enables setting of the
+ txfilltuning field in the EHCI controller on reset.
+
+ CONFIG_USB_DWC2_REG_ADDR the physical CPU address of the DWC2
+ HW module registers.
+
+- USB Device:
+ Define the below if you wish to use the USB console.
+ Once firmware is rebuilt from a serial console issue the
+ command "setenv stdin usbtty; setenv stdout usbtty" and
+ attach your USB cable. The Unix command "dmesg" should print
+ it has found a new device. The environment variable usbtty
+ can be set to gserial or cdc_acm to enable your device to
+ appear to a USB host as a Linux gserial device or a
+ Common Device Class Abstract Control Model serial device.
+ If you select usbtty = gserial you should be able to enumerate
+ a Linux host by
+ # modprobe usbserial vendor=0xVendorID product=0xProductID
+ else if using cdc_acm, simply setting the environment
+ variable usbtty to be cdc_acm should suffice. The following
+ might be defined in YourBoardName.h
+
+ CONFIG_USB_DEVICE
+ Define this to build a UDC device
+
+ CONFIG_USB_TTY
+ Define this to have a tty type of device available to
+ talk to the UDC device
+
+ CONFIG_USBD_HS
+ Define this to enable the high speed support for usb
+ device and usbtty. If this feature is enabled, a routine
+ int is_usbd_high_speed(void)
+ also needs to be defined by the driver to dynamically poll
+ whether the enumeration has succeded at high speed or full
+ speed.
+
+ CONFIG_SYS_CONSOLE_IS_IN_ENV
+ Define this if you want stdin, stdout &/or stderr to
+ be set to usbtty.
+
+ If you have a USB-IF assigned VendorID then you may wish to
+ define your own vendor specific values either in BoardName.h
+ or directly in usbd_vendor_info.h. If you don't define
+ CONFIG_USBD_MANUFACTURER, CONFIG_USBD_PRODUCT_NAME,
+ CONFIG_USBD_VENDORID and CONFIG_USBD_PRODUCTID, then U-Boot
+ should pretend to be a Linux device to it's target host.
+
+ CONFIG_USBD_MANUFACTURER
+ Define this string as the name of your company for
+ - CONFIG_USBD_MANUFACTURER "my company"
+
+ CONFIG_USBD_PRODUCT_NAME
+ Define this string as the name of your product
+ - CONFIG_USBD_PRODUCT_NAME "acme usb device"
+
+ CONFIG_USBD_VENDORID
+ Define this as your assigned Vendor ID from the USB
+ Implementors Forum. This *must* be a genuine Vendor ID
+ to avoid polluting the USB namespace.
+ - CONFIG_USBD_VENDORID 0xFFFF
+
+ CONFIG_USBD_PRODUCTID
+ Define this as the unique Product ID
+ for your device
+ - CONFIG_USBD_PRODUCTID 0xFFFF
+
+- ULPI Layer Support:
+ The ULPI (UTMI Low Pin (count) Interface) PHYs are supported via
+ the generic ULPI layer. The generic layer accesses the ULPI PHY
+ via the platform viewport, so you need both the genric layer and
+ the viewport enabled. Currently only Chipidea/ARC based
+ viewport is supported.
+ To enable the ULPI layer support, define CONFIG_USB_ULPI and
+ CONFIG_USB_ULPI_VIEWPORT in your board configuration file.
+ If your ULPI phy needs a different reference clock than the
+ standard 24 MHz then you have to define CONFIG_ULPI_REF_CLK to
+ the appropriate value in Hz.
+
+- MMC Support:
+ The MMC controller on the Intel PXA is supported. To
+ enable this define CONFIG_MMC. The MMC can be
+ accessed from the boot prompt by mapping the device
+ to physical memory similar to flash. Command line is
+ enabled with CONFIG_CMD_MMC. The MMC driver also works with
+ the FAT fs. This is enabled with CONFIG_CMD_FAT.
+
+ CONFIG_SH_MMCIF
+ Support for Renesas on-chip MMCIF controller
+
+ CONFIG_SH_MMCIF_ADDR
+ Define the base address of MMCIF registers
+
+ CONFIG_SH_MMCIF_CLK
+ Define the clock frequency for MMCIF
+
+ CONFIG_SUPPORT_EMMC_BOOT
+ Enable some additional features of the eMMC boot partitions.
+
+- USB Device Firmware Update (DFU) class support:
+ CONFIG_DFU_OVER_USB
+ This enables the USB portion of the DFU USB class
+
+ CONFIG_DFU_MMC
+ This enables support for exposing (e)MMC devices via DFU.
+
+ CONFIG_DFU_NAND
+ This enables support for exposing NAND devices via DFU.
+
+ CONFIG_DFU_RAM
+ This enables support for exposing RAM via DFU.
+ Note: DFU spec refer to non-volatile memory usage, but
+ allow usages beyond the scope of spec - here RAM usage,
+ one that would help mostly the developer.
+
+ CONFIG_SYS_DFU_DATA_BUF_SIZE
+ Dfu transfer uses a buffer before writing data to the
+ raw storage device. Make the size (in bytes) of this buffer
+ configurable. The size of this buffer is also configurable
+ through the "dfu_bufsiz" environment variable.
+
+ CONFIG_SYS_DFU_MAX_FILE_SIZE
+ When updating files rather than the raw storage device,
+ we use a static buffer to copy the file into and then write
+ the buffer once we've been given the whole file. Define
+ this to the maximum filesize (in bytes) for the buffer.
+ Default is 4 MiB if undefined.
+
+ DFU_DEFAULT_POLL_TIMEOUT
+ Poll timeout [ms], is the timeout a device can send to the
+ host. The host must wait for this timeout before sending
+ a subsequent DFU_GET_STATUS request to the device.
+
+ DFU_MANIFEST_POLL_TIMEOUT
+ Poll timeout [ms], which the device sends to the host when
+ entering dfuMANIFEST state. Host waits this timeout, before
+ sending again an USB request to the device.
+
+- Journaling Flash filesystem support:
+ CONFIG_JFFS2_NAND
+ Define these for a default partition on a NAND device
+
+ CONFIG_SYS_JFFS2_FIRST_SECTOR,
+ CONFIG_SYS_JFFS2_FIRST_BANK, CONFIG_SYS_JFFS2_NUM_BANKS
+ Define these for a default partition on a NOR device
+
+- Keyboard Support:
+ See Kconfig help for available keyboard drivers.
+
+ CONFIG_KEYBOARD
+
+ Define this to enable a custom keyboard support.
+ This simply calls drv_keyboard_init() which must be
+ defined in your board-specific files. This option is deprecated
+ and is only used by novena. For new boards, use driver model
+ instead.
+
+- Video support:
+ CONFIG_FSL_DIU_FB
+ Enable the Freescale DIU video driver. Reference boards for
+ SOCs that have a DIU should define this macro to enable DIU
+ support, and should also define these other macros:
+
+ CONFIG_SYS_DIU_ADDR
+ CONFIG_VIDEO
+ CONFIG_CFB_CONSOLE
+ CONFIG_VIDEO_SW_CURSOR
+ CONFIG_VGA_AS_SINGLE_DEVICE
+ CONFIG_VIDEO_LOGO
+ CONFIG_VIDEO_BMP_LOGO
+
+ The DIU driver will look for the 'video-mode' environment
+ variable, and if defined, enable the DIU as a console during
+ boot. See the documentation file doc/README.video for a
+ description of this variable.
+
+- LCD Support: CONFIG_LCD
+
+ Define this to enable LCD support (for output to LCD
+ display); also select one of the supported displays
+ by defining one of these:
+
+ CONFIG_ATMEL_LCD:
+
+ HITACHI TX09D70VM1CCA, 3.5", 240x320.
+
+ CONFIG_NEC_NL6448AC33:
+
+ NEC NL6448AC33-18. Active, color, single scan.
+
+ CONFIG_NEC_NL6448BC20
+
+ NEC NL6448BC20-08. 6.5", 640x480.
+ Active, color, single scan.
+
+ CONFIG_NEC_NL6448BC33_54
+
+ NEC NL6448BC33-54. 10.4", 640x480.
+ Active, color, single scan.
+
+ CONFIG_SHARP_16x9
+
+ Sharp 320x240. Active, color, single scan.
+ It isn't 16x9, and I am not sure what it is.
+
+ CONFIG_SHARP_LQ64D341
+
+ Sharp LQ64D341 display, 640x480.
+ Active, color, single scan.
+
+ CONFIG_HLD1045
+
+ HLD1045 display, 640x480.
+ Active, color, single scan.
+
+ CONFIG_OPTREX_BW
+
+ Optrex CBL50840-2 NF-FW 99 22 M5
+ or
+ Hitachi LMG6912RPFC-00T
+ or
+ Hitachi SP14Q002
+
+ 320x240. Black & white.
+
+ CONFIG_LCD_ALIGNMENT
+
+ Normally the LCD is page-aligned (typically 4KB). If this is
+ defined then the LCD will be aligned to this value instead.
+ For ARM it is sometimes useful to use MMU_SECTION_SIZE
+ here, since it is cheaper to change data cache settings on
+ a per-section basis.
+
+
+ CONFIG_LCD_ROTATION
+
+ Sometimes, for example if the display is mounted in portrait
+ mode or even if it's mounted landscape but rotated by 180degree,
+ we need to rotate our content of the display relative to the
+ framebuffer, so that user can read the messages which are
+ printed out.
+ Once CONFIG_LCD_ROTATION is defined, the lcd_console will be
+ initialized with a given rotation from "vl_rot" out of
+ "vidinfo_t" which is provided by the board specific code.
+ The value for vl_rot is coded as following (matching to
+ fbcon=rotate:<n> linux-kernel commandline):
+ 0 = no rotation respectively 0 degree
+ 1 = 90 degree rotation
+ 2 = 180 degree rotation
+ 3 = 270 degree rotation
+
+ If CONFIG_LCD_ROTATION is not defined, the console will be
+ initialized with 0degree rotation.
+
+ CONFIG_LCD_BMP_RLE8
+
+ Support drawing of RLE8-compressed bitmaps on the LCD.
+
+ CONFIG_I2C_EDID
+
+ Enables an 'i2c edid' command which can read EDID
+ information over I2C from an attached LCD display.
+
+- Splash Screen Support: CONFIG_SPLASH_SCREEN
+
+ If this option is set, the environment is checked for
+ a variable "splashimage". If found, the usual display
+ of logo, copyright and system information on the LCD
+ is suppressed and the BMP image at the address
+ specified in "splashimage" is loaded instead. The
+ console is redirected to the "nulldev", too. This
+ allows for a "silent" boot where a splash screen is
+ loaded very quickly after power-on.
+
+ CONFIG_SPLASHIMAGE_GUARD
+
+ If this option is set, then U-Boot will prevent the environment
+ variable "splashimage" from being set to a problematic address
+ (see doc/README.displaying-bmps).
+ This option is useful for targets where, due to alignment
+ restrictions, an improperly aligned BMP image will cause a data
+ abort. If you think you will not have problems with unaligned
+ accesses (for example because your toolchain prevents them)
+ there is no need to set this option.
+
+ CONFIG_SPLASH_SCREEN_ALIGN
+
+ If this option is set the splash image can be freely positioned
+ on the screen. Environment variable "splashpos" specifies the
+ position as "x,y". If a positive number is given it is used as
+ number of pixel from left/top. If a negative number is given it
+ is used as number of pixel from right/bottom. You can also
+ specify 'm' for centering the image.
+
+ Example:
+ setenv splashpos m,m
+ => image at center of screen
+
+ setenv splashpos 30,20
+ => image at x = 30 and y = 20
+
+ setenv splashpos -10,m
+ => vertically centered image
+ at x = dspWidth - bmpWidth - 9
+
+- Gzip compressed BMP image support: CONFIG_VIDEO_BMP_GZIP
+
+ If this option is set, additionally to standard BMP
+ images, gzipped BMP images can be displayed via the
+ splashscreen support or the bmp command.
+
+- Run length encoded BMP image (RLE8) support: CONFIG_VIDEO_BMP_RLE8
+
+ If this option is set, 8-bit RLE compressed BMP images
+ can be displayed via the splashscreen support or the
+ bmp command.
+
+- Compression support:
+ CONFIG_GZIP
+
+ Enabled by default to support gzip compressed images.
+
+ CONFIG_BZIP2
+
+ If this option is set, support for bzip2 compressed
+ images is included. If not, only uncompressed and gzip
+ compressed images are supported.
+
+ NOTE: the bzip2 algorithm requires a lot of RAM, so
+ the malloc area (as defined by CONFIG_SYS_MALLOC_LEN) should
+ be at least 4MB.
+
+- MII/PHY support:
+ CONFIG_PHY_CLOCK_FREQ (ppc4xx)
+
+ The clock frequency of the MII bus
+
+ CONFIG_PHY_RESET_DELAY
+
+ Some PHY like Intel LXT971A need extra delay after
+ reset before any MII register access is possible.
+ For such PHY, set this option to the usec delay
+ required. (minimum 300usec for LXT971A)
+
+ CONFIG_PHY_CMD_DELAY (ppc4xx)
+
+ Some PHY like Intel LXT971A need extra delay after
+ command issued before MII status register can be read
+
+- IP address:
+ CONFIG_IPADDR
+
+ Define a default value for the IP address to use for
+ the default Ethernet interface, in case this is not
+ determined through e.g. bootp.
+ (Environment variable "ipaddr")
+
+- Server IP address:
+ CONFIG_SERVERIP
+
+ Defines a default value for the IP address of a TFTP
+ server to contact when using the "tftboot" command.
+ (Environment variable "serverip")
+
+ CONFIG_KEEP_SERVERADDR
+
+ Keeps the server's MAC address, in the env 'serveraddr'
+ for passing to bootargs (like Linux's netconsole option)
+
+- Gateway IP address:
+ CONFIG_GATEWAYIP
+
+ Defines a default value for the IP address of the
+ default router where packets to other networks are
+ sent to.
+ (Environment variable "gatewayip")
+
+- Subnet mask:
+ CONFIG_NETMASK
+
+ Defines a default value for the subnet mask (or
+ routing prefix) which is used to determine if an IP
+ address belongs to the local subnet or needs to be
+ forwarded through a router.
+ (Environment variable "netmask")
+
+- Multicast TFTP Mode:
+ CONFIG_MCAST_TFTP
+
+ Defines whether you want to support multicast TFTP as per
+ rfc-2090; for example to work with atftp. Lets lots of targets
+ tftp down the same boot image concurrently. Note: the Ethernet
+ driver in use must provide a function: mcast() to join/leave a
+ multicast group.
+
+- BOOTP Recovery Mode:
+ CONFIG_BOOTP_RANDOM_DELAY
+
+ If you have many targets in a network that try to
+ boot using BOOTP, you may want to avoid that all
+ systems send out BOOTP requests at precisely the same
+ moment (which would happen for instance at recovery
+ from a power failure, when all systems will try to
+ boot, thus flooding the BOOTP server. Defining
+ CONFIG_BOOTP_RANDOM_DELAY causes a random delay to be
+ inserted before sending out BOOTP requests. The
+ following delays are inserted then:
+
+ 1st BOOTP request: delay 0 ... 1 sec
+ 2nd BOOTP request: delay 0 ... 2 sec
+ 3rd BOOTP request: delay 0 ... 4 sec
+ 4th and following
+ BOOTP requests: delay 0 ... 8 sec
+
+ CONFIG_BOOTP_ID_CACHE_SIZE
+
+ BOOTP packets are uniquely identified using a 32-bit ID. The
+ server will copy the ID from client requests to responses and
+ U-Boot will use this to determine if it is the destination of
+ an incoming response. Some servers will check that addresses
+ aren't in use before handing them out (usually using an ARP
+ ping) and therefore take up to a few hundred milliseconds to
+ respond. Network congestion may also influence the time it
+ takes for a response to make it back to the client. If that
+ time is too long, U-Boot will retransmit requests. In order
+ to allow earlier responses to still be accepted after these
+ retransmissions, U-Boot's BOOTP client keeps a small cache of
+ IDs. The CONFIG_BOOTP_ID_CACHE_SIZE controls the size of this
+ cache. The default is to keep IDs for up to four outstanding
+ requests. Increasing this will allow U-Boot to accept offers
+ from a BOOTP client in networks with unusually high latency.
+
+- DHCP Advanced Options:
+ You can fine tune the DHCP functionality by defining
+ CONFIG_BOOTP_* symbols:
+
+ CONFIG_BOOTP_NISDOMAIN
+ CONFIG_BOOTP_BOOTFILESIZE
+ CONFIG_BOOTP_SEND_HOSTNAME
+ CONFIG_BOOTP_NTPSERVER
+ CONFIG_BOOTP_TIMEOFFSET
+ CONFIG_BOOTP_VENDOREX
+ CONFIG_BOOTP_MAY_FAIL
+
+ CONFIG_BOOTP_SERVERIP - TFTP server will be the serverip
+ environment variable, not the BOOTP server.
+
+ CONFIG_BOOTP_MAY_FAIL - If the DHCP server is not found
+ after the configured retry count, the call will fail
+ instead of starting over. This can be used to fail over
+ to Link-local IP address configuration if the DHCP server
+ is not available.
+
+ CONFIG_BOOTP_SEND_HOSTNAME - Some DHCP servers are capable
+ to do a dynamic update of a DNS server. To do this, they
+ need the hostname of the DHCP requester.
+ If CONFIG_BOOTP_SEND_HOSTNAME is defined, the content
+ of the "hostname" environment variable is passed as
+ option 12 to the DHCP server.
+
+ CONFIG_BOOTP_DHCP_REQUEST_DELAY
+
+ A 32bit value in microseconds for a delay between
+ receiving a "DHCP Offer" and sending the "DHCP Request".
+ This fixes a problem with certain DHCP servers that don't
+ respond 100% of the time to a "DHCP request". E.g. On an
+ AT91RM9200 processor running at 180MHz, this delay needed
+ to be *at least* 15,000 usec before a Windows Server 2003
+ DHCP server would reply 100% of the time. I recommend at
+ least 50,000 usec to be safe. The alternative is to hope
+ that one of the retries will be successful but note that
+ the DHCP timeout and retry process takes a longer than
+ this delay.
+
+ - Link-local IP address negotiation:
+ Negotiate with other link-local clients on the local network
+ for an address that doesn't require explicit configuration.
+ This is especially useful if a DHCP server cannot be guaranteed
+ to exist in all environments that the device must operate.
+
+ See doc/README.link-local for more information.
+
+ - MAC address from environment variables
+
+ FDT_SEQ_MACADDR_FROM_ENV
+
+ Fix-up device tree with MAC addresses fetched sequentially from
+ environment variables. This config work on assumption that
+ non-usable ethernet node of device-tree are either not present
+ or their status has been marked as "disabled".
+
+ - CDP Options:
+ CONFIG_CDP_DEVICE_ID
+
+ The device id used in CDP trigger frames.
+
+ CONFIG_CDP_DEVICE_ID_PREFIX
+
+ A two character string which is prefixed to the MAC address
+ of the device.
+
+ CONFIG_CDP_PORT_ID
+
+ A printf format string which contains the ascii name of
+ the port. Normally is set to "eth%d" which sets
+ eth0 for the first Ethernet, eth1 for the second etc.
+
+ CONFIG_CDP_CAPABILITIES
+
+ A 32bit integer which indicates the device capabilities;
+ 0x00000010 for a normal host which does not forwards.
+
+ CONFIG_CDP_VERSION
+
+ An ascii string containing the version of the software.
+
+ CONFIG_CDP_PLATFORM
+
+ An ascii string containing the name of the platform.
+
+ CONFIG_CDP_TRIGGER
+
+ A 32bit integer sent on the trigger.
+
+ CONFIG_CDP_POWER_CONSUMPTION
+
+ A 16bit integer containing the power consumption of the
+ device in .1 of milliwatts.
+
+ CONFIG_CDP_APPLIANCE_VLAN_TYPE
+
+ A byte containing the id of the VLAN.
+
+- Status LED: CONFIG_LED_STATUS
+
+ Several configurations allow to display the current
+ status using a LED. For instance, the LED will blink
+ fast while running U-Boot code, stop blinking as
+ soon as a reply to a BOOTP request was received, and
+ start blinking slow once the Linux kernel is running
+ (supported by a status LED driver in the Linux
+ kernel). Defining CONFIG_LED_STATUS enables this
+ feature in U-Boot.
+
+ Additional options:
+
+ CONFIG_LED_STATUS_GPIO
+ The status LED can be connected to a GPIO pin.
+ In such cases, the gpio_led driver can be used as a
+ status LED backend implementation. Define CONFIG_LED_STATUS_GPIO
+ to include the gpio_led driver in the U-Boot binary.
+
+ CONFIG_GPIO_LED_INVERTED_TABLE
+ Some GPIO connected LEDs may have inverted polarity in which
+ case the GPIO high value corresponds to LED off state and
+ GPIO low value corresponds to LED on state.
+ In such cases CONFIG_GPIO_LED_INVERTED_TABLE may be defined
+ with a list of GPIO LEDs that have inverted polarity.
+
+- I2C Support: CONFIG_SYS_I2C
+
+ This enable the NEW i2c subsystem, and will allow you to use
+ i2c commands at the u-boot command line (as long as you set
+ CONFIG_CMD_I2C in CONFIG_COMMANDS) and communicate with i2c
+ based realtime clock chips or other i2c devices. See
+ common/cmd_i2c.c for a description of the command line
+ interface.

+
+ additional defines:
+
+ CONFIG_SYS_NUM_I2C_BUSES
+ Hold the number of i2c buses you want to use.
+
+ CONFIG_SYS_I2C_DIRECT_BUS
+ define this, if you don't use i2c muxes on your hardware.
+ if CONFIG_SYS_I2C_MAX_HOPS is not defined or == 0 you can
+ omit this define.
+
+ CONFIG_SYS_I2C_MAX_HOPS
+ define how many muxes are maximal consecutively connected
+ on one i2c bus. If you not use i2c muxes, omit this
+ define.
+
+ CONFIG_SYS_I2C_BUSES
+ hold a list of buses you want to use, only used if
+ CONFIG_SYS_I2C_DIRECT_BUS is not defined, for example
+ a board with CONFIG_SYS_I2C_MAX_HOPS = 1 and
+ CONFIG_SYS_NUM_I2C_BUSES = 9:
+
+ CONFIG_SYS_I2C_BUSES {{0, {I2C_NULL_HOP}}, \
+ {0, {{I2C_MUX_PCA9547, 0x70, 1}}}, \
+ {0, {{I2C_MUX_PCA9547, 0x70, 2}}}, \
+ {0, {{I2C_MUX_PCA9547, 0x70, 3}}}, \
+ {0, {{I2C_MUX_PCA9547, 0x70, 4}}}, \
+ {0, {{I2C_MUX_PCA9547, 0x70, 5}}}, \
+ {1, {I2C_NULL_HOP}}, \
+ {1, {{I2C_MUX_PCA9544, 0x72, 1}}}, \
+ {1, {{I2C_MUX_PCA9544, 0x72, 2}}}, \
+ }
+
+ which defines
+ bus 0 on adapter 0 without a mux
+ bus 1 on adapter 0 with a PCA9547 on address 0x70 port 1
+ bus 2 on adapter 0 with a PCA9547 on address 0x70 port 2
+ bus 3 on adapter 0 with a PCA9547 on address 0x70 port 3
+ bus 4 on adapter 0 with a PCA9547 on address 0x70 port 4
+ bus 5 on adapter 0 with a PCA9547 on address 0x70 port 5
+ bus 6 on adapter 1 without a mux
+ bus 7 on adapter 1 with a PCA9544 on address 0x72 port 1
+ bus 8 on adapter 1 with a PCA9544 on address 0x72 port 2
+
+ If you do not have i2c muxes on your board, omit this define.
+
+- Legacy I2C Support:
+ If you use the software i2c interface (CONFIG_SYS_I2C_SOFT)
+ then the following macros need to be defined (examples are
+ from include/configs/lwmon.h):
+
+ I2C_INIT
+
+ (Optional). Any commands necessary to enable the I2C
+ controller or configure ports.
+
+ eg: #define I2C_INIT (immr->im_cpm.cp_pbdir |= PB_SCL)
+
+ I2C_ACTIVE
+
+ The code necessary to make the I2C data line active
+ (driven). If the data line is open collector, this
+ define can be null.
+
+ eg: #define I2C_ACTIVE (immr->im_cpm.cp_pbdir |= PB_SDA)
+
+ I2C_TRISTATE
+
+ The code necessary to make the I2C data line tri-stated
+ (inactive). If the data line is open collector, this
+ define can be null.
+
+ eg: #define I2C_TRISTATE (immr->im_cpm.cp_pbdir &= ~PB_SDA)
+
+ I2C_READ
+
+ Code that returns true if the I2C data line is high,
+ false if it is low.
+
+ eg: #define I2C_READ ((immr->im_cpm.cp_pbdat & PB_SDA) != 0)
+
+ I2C_SDA(bit)
+
+ If <bit> is true, sets the I2C data line high. If it
+ is false, it clears it (low).
+
+ eg: #define I2C_SDA(bit) \
+ if(bit) immr->im_cpm.cp_pbdat |= PB_SDA; \
+ else immr->im_cpm.cp_pbdat &= ~PB_SDA
+
+ I2C_SCL(bit)
+
+ If <bit> is true, sets the I2C clock line high. If it
+ is false, it clears it (low).
+
+ eg: #define I2C_SCL(bit) \
+ if(bit) immr->im_cpm.cp_pbdat |= PB_SCL; \
+ else immr->im_cpm.cp_pbdat &= ~PB_SCL
+
+ I2C_DELAY
+
+ This delay is invoked four times per clock cycle so this
+ controls the rate of data transfer. The data rate thus
+ is 1 / (I2C_DELAY * 4). Often defined to be something
+ like:
+
+ #define I2C_DELAY udelay(2)
+
+ CONFIG_SOFT_I2C_GPIO_SCL / CONFIG_SOFT_I2C_GPIO_SDA
+
+ If your arch supports the generic GPIO framework (asm/gpio.h),
+ then you may alternatively define the two GPIOs that are to be
+ used as SCL / SDA. Any of the previous I2C_xxx macros will
+ have GPIO-based defaults assigned to them as appropriate.
+
+ You should define these to the GPIO value as given directly to
+ the generic GPIO functions.
+
+ CONFIG_SYS_I2C_INIT_BOARD
+
+ When a board is reset during an i2c bus transfer
+ chips might think that the current transfer is still
+ in progress. On some boards it is possible to access
+ the i2c SCLK line directly, either by using the
+ processor pin as a GPIO or by having a second pin
+ connected to the bus. If this option is defined a
+ custom i2c_init_board() routine in boards/xxx/board.c
+ is run early in the boot sequence.
+
+ CONFIG_I2C_MULTI_BUS
+
+ This option allows the use of multiple I2C buses, each of which
+ must have a controller. At any point in time, only one bus is
+ active. To switch to a different bus, use the 'i2c dev' command.
+ Note that bus numbering is zero-based.
+
+ CONFIG_SYS_I2C_NOPROBES
+
+ This option specifies a list of I2C devices that will be skipped
+ when the 'i2c probe' command is issued. If CONFIG_I2C_MULTI_BUS
+ is set, specify a list of bus-device pairs. Otherwise, specify
+ a 1D array of device addresses
+
+ e.g.
+ #undef CONFIG_I2C_MULTI_BUS
+ #define CONFIG_SYS_I2C_NOPROBES {0x50,0x68}
+
+ will skip addresses 0x50 and 0x68 on a board with one I2C bus
+
+ #define CONFIG_I2C_MULTI_BUS
+ #define CONFIG_SYS_I2C_NOPROBES {{0,0x50},{0,0x68},{1,0x54}}
+
+ will skip addresses 0x50 and 0x68 on bus 0 and address 0x54 on bus 1
+
+ CONFIG_SYS_SPD_BUS_NUM
+
+ If defined, then this indicates the I2C bus number for DDR SPD.
+ If not defined, then U-Boot assumes that SPD is on I2C bus 0.
+
+ CONFIG_SYS_RTC_BUS_NUM
+
+ If defined, then this indicates the I2C bus number for the RTC.
+ If not defined, then U-Boot assumes that RTC is on I2C bus 0.
+
+ CONFIG_SOFT_I2C_READ_REPEATED_START
+
+ defining this will force the i2c_read() function in
+ the soft_i2c driver to perform an I2C repeated start
+ between writing the address pointer and reading the
+ data. If this define is omitted the default behaviour
+ of doing a stop-start sequence will be used. Most I2C
+ devices can use either method, but some require one or
+ the other.
+
+- SPI Support: CONFIG_SPI
+
+ Enables SPI driver (so far only tested with
+ SPI EEPROM, also an instance works with Crystal A/D and
+ D/As on the SACSng board)
+
+ CONFIG_SOFT_SPI
+
+ Enables a software (bit-bang) SPI driver rather than
+ using hardware support. This is a general purpose
+ driver that only requires three general I/O port pins
+ (two outputs, one input) to function. If this is
+ defined, the board configuration must define several
+ SPI configuration items (port pins to use, etc). For
+ an example, see include/configs/sacsng.h.
+
+ CONFIG_SYS_SPI_MXC_WAIT
+ Timeout for waiting until spi transfer completed.
+ default: (CONFIG_SYS_HZ/100) /* 10 ms */
+
+- FPGA Support: CONFIG_FPGA
+
+ Enables FPGA subsystem.
+
+ CONFIG_FPGA_<vendor>
+
+ Enables support for specific chip vendors.
+ (ALTERA, XILINX)
+
+ CONFIG_FPGA_<family>
+
+ Enables support for FPGA family.
+ (SPARTAN2, SPARTAN3, VIRTEX2, CYCLONE2, ACEX1K, ACEX)
+
+ CONFIG_FPGA_COUNT
+
+ Specify the number of FPGA devices to support.
+
+ CONFIG_SYS_FPGA_PROG_FEEDBACK
+
+ Enable printing of hash marks during FPGA configuration.
+
+ CONFIG_SYS_FPGA_CHECK_BUSY
+
+ Enable checks on FPGA configuration interface busy
+ status by the configuration function. This option
+ will require a board or device specific function to
+ be written.
+
+ CONFIG_FPGA_DELAY
+
+ If defined, a function that provides delays in the FPGA
+ configuration driver.
+
+ CONFIG_SYS_FPGA_CHECK_CTRLC
+ Allow Control-C to interrupt FPGA configuration
+
+ CONFIG_SYS_FPGA_CHECK_ERROR
+
+ Check for configuration errors during FPGA bitfile
+ loading. For example, abort during Virtex II
+ configuration if the INIT_B line goes low (which
+ indicated a CRC error).
+
+ CONFIG_SYS_FPGA_WAIT_INIT
+
+ Maximum time to wait for the INIT_B line to de-assert
+ after PROB_B has been de-asserted during a Virtex II
+ FPGA configuration sequence. The default time is 500
+ ms.
+
+ CONFIG_SYS_FPGA_WAIT_BUSY
+
+ Maximum time to wait for BUSY to de-assert during
+ Virtex II FPGA configuration. The default is 5 ms.
+
+ CONFIG_SYS_FPGA_WAIT_CONFIG
+
+ Time to wait after FPGA configuration. The default is
+ 200 ms.
+
+- Configuration Management:
+ CONFIG_BUILD_TARGET
+
+ Some SoCs need special image types (e.g. U-Boot binary
+ with a special header) as build targets. By defining
+ CONFIG_BUILD_TARGET in the SoC / board header, this
+ special image will be automatically built upon calling
+ make / buildman.
+
+ CONFIG_IDENT_STRING
+
+ If defined, this string will be added to the U-Boot
+ version information (U_BOOT_VERSION)
+
+- Vendor Parameter Protection:
+
+ U-Boot considers the values of the environment
+ variables "serial#" (Board Serial Number) and
+ "ethaddr" (Ethernet Address) to be parameters that
+ are set once by the board vendor / manufacturer, and
+ protects these variables from casual modification by
+ the user. Once set, these variables are read-only,
+ and write or delete attempts are rejected. You can
+ change this behaviour:
+
+ If CONFIG_ENV_OVERWRITE is #defined in your config
+ file, the write protection for vendor parameters is
+ completely disabled. Anybody can change or delete
+ these parameters.
+
+ Alternatively, if you define _both_ an ethaddr in the
+ default env _and_ CONFIG_OVERWRITE_ETHADDR_ONCE, a default
+ Ethernet address is installed in the environment,
+ which can be changed exactly ONCE by the user. [The
+ serial# is unaffected by this, i. e. it remains
+ read-only.]
+
+ The same can be accomplished in a more flexible way
+ for any variable by configuring the type of access
+ to allow for those variables in the ".flags" variable
+ or define CONFIG_ENV_FLAGS_LIST_STATIC.
+
+- Protected RAM:
+ CONFIG_PRAM
+
+ Define this variable to enable the reservation of
+ "protected RAM", i. e. RAM which is not overwritten
+ by U-Boot. Define CONFIG_PRAM to hold the number of
+ kB you want to reserve for pRAM. You can overwrite
+ this default value by defining an environment
+ variable "pram" to the number of kB you want to
+ reserve. Note that the board info structure will
+ still show the full amount of RAM. If pRAM is
+ reserved, a new environment variable "mem" will
+ automatically be defined to hold the amount of
+ remaining RAM in a form that can be passed as boot
+ argument to Linux, for instance like that:
+
+ setenv bootargs ... mem=\${mem}
+ saveenv
+
+ This way you can tell Linux not to use this memory,
+ either, which results in a memory region that will
+ not be affected by reboots.
+
+ *WARNING* If your board configuration uses automatic
+ detection of the RAM size, you must make sure that
+ this memory test is non-destructive. So far, the
+ following board configurations are known to be
+ "pRAM-clean":
+
+ IVMS8, IVML24, SPD8xx,
+ HERMES, IP860, RPXlite, LWMON,
+ FLAGADM
+
+- Access to physical memory region (> 4GB)
+ Some basic support is provided for operations on memory not
+ normally accessible to U-Boot - e.g. some architectures
+ support access to more than 4GB of memory on 32-bit
+ machines using physical address extension or similar.
+ Define CONFIG_PHYSMEM to access this basic support, which
+ currently only supports clearing the memory.
+
+- Error Recovery:
+ CONFIG_NET_RETRY_COUNT
+
+ This variable defines the number of retries for
+ network operations like ARP, RARP, TFTP, or BOOTP
+ before giving up the operation. If not defined, a
+ default value of 5 is used.
+
+ CONFIG_ARP_TIMEOUT
+
+ Timeout waiting for an ARP reply in milliseconds.
+
+ CONFIG_NFS_TIMEOUT
+
+ Timeout in milliseconds used in NFS protocol.
+ If you encounter "ERROR: Cannot umount" in nfs command,
+ try longer timeout such as
+ #define CONFIG_NFS_TIMEOUT 10000UL
+
+- Command Interpreter:
+ CONFIG_SYS_PROMPT_HUSH_PS2
+
+ This defines the secondary prompt string, which is
+ printed when the command interpreter needs more input
+ to complete a command. Usually "> ".
+
+ Note:
+
+ In the current implementation, the local variables
+ space and global environment variables space are
+ separated. Local variables are those you define by
+ simply typing `name=value'. To access a local
+ variable later on, you have write `$name' or
+ `${name}'; to execute the contents of a variable
+ directly type `$name' at the command prompt.
+
+ Global environment variables are those you use
+ setenv/printenv to work with. To run a command stored
+ in such a variable, you need to use the run command,
+ and you must not use the '$' sign to access them.
+
+ To store commands and special characters in a
+ variable, please use double quotation marks
+ surrounding the whole text of the variable, instead
+ of the backslashes before semicolons and special
+ symbols.
+
+- Command Line Editing and History:
+ CONFIG_CMDLINE_PS_SUPPORT
+
+ Enable support for changing the command prompt string
+ at run-time. Only static string is supported so far.
+ The string is obtained from environment variables PS1
+ and PS2.
+
+- Default Environment:
+ CONFIG_EXTRA_ENV_SETTINGS
+
+ Define this to contain any number of null terminated
+ strings (variable = value pairs) that will be part of
+ the default environment compiled into the boot image.
+
+ For example, place something like this in your
+ board's config file:
+
+ #define CONFIG_EXTRA_ENV_SETTINGS \
+ "myvar1=value1\0" \
+ "myvar2=value2\0"
+
+ Warning: This method is based on knowledge about the
+ internal format how the environment is stored by the
+ U-Boot code. This is NOT an official, exported
+ interface! Although it is unlikely that this format
+ will change soon, there is no guarantee either.
+ You better know what you are doing here.
+
+ Note: overly (ab)use of the default environment is
+ discouraged. Make sure to check other ways to preset
+ the environment like the "source" command or the
+ boot command first.
+
+ CONFIG_DELAY_ENVIRONMENT
+
+ Normally the environment is loaded when the board is
+ initialised so that it is available to U-Boot. This inhibits
+ that so that the environment is not available until
+ explicitly loaded later by U-Boot code. With CONFIG_OF_CONTROL
+ this is instead controlled by the value of
+ /config/load-environment.
+
+- Serial Flash support
+ Usage requires an initial 'sf probe' to define the serial
+ flash parameters, followed by read/write/erase/update
+ commands.
+
+ The following defaults may be provided by the platform
+ to handle the common case when only a single serial
+ flash is present on the system.
+
+ CONFIG_SF_DEFAULT_BUS Bus identifier
+ CONFIG_SF_DEFAULT_CS Chip-select
+ CONFIG_SF_DEFAULT_MODE (see include/spi.h)
+ CONFIG_SF_DEFAULT_SPEED in Hz
+
+
+- TFTP Fixed UDP Port:
+ CONFIG_TFTP_PORT
+
+ If this is defined, the environment variable tftpsrcp
+ is used to supply the TFTP UDP source port value.
+ If tftpsrcp isn't defined, the normal pseudo-random port
+ number generator is used.
+
+ Also, the environment variable tftpdstp is used to supply
+ the TFTP UDP destination port value. If tftpdstp isn't
+ defined, the normal port 69 is used.
+
+ The purpose for tftpsrcp is to allow a TFTP server to
+ blindly start the TFTP transfer using the pre-configured
+ target IP address and UDP port. This has the effect of
+ "punching through" the (Windows XP) firewall, allowing
+ the remainder of the TFTP transfer to proceed normally.
+ A better solution is to properly configure the firewall,
+ but sometimes that is not allowed.
+
+- Show boot progress:
+ CONFIG_SHOW_BOOT_PROGRESS
+
+ Defining this option allows to add some board-
+ specific code (calling a user-provided function
+ "show_boot_progress(int)") that enables you to show
+ the system's boot progress on some display (for
+ example, some LED's) on your board. At the moment,
+ the following checkpoints are implemented:
+

+
+- Standalone program support:
+ CONFIG_STANDALONE_LOAD_ADDR
+
+ This option defines a board specific value for the
+ address where standalone program gets loaded, thus
+ overwriting the architecture dependent default
+ settings.
+
+- Frame Buffer Address:
+ CONFIG_FB_ADDR
+
+ Define CONFIG_FB_ADDR if you want to use specific
+ address for frame buffer. This is typically the case
+ when using a graphics controller has separate video
+ memory. U-Boot will then place the frame buffer at
+ the given address instead of dynamically reserving it
+ in system RAM by calling lcd_setmem(), which grabs
+ the memory for the frame buffer depending on the
+ configured panel size.
+
+ Please see board_init_f function.
+
+- Automatic software updates via TFTP server
+ CONFIG_UPDATE_TFTP
+ CONFIG_UPDATE_TFTP_CNT_MAX
+ CONFIG_UPDATE_TFTP_MSEC_MAX
+
+ These options enable and control the auto-update feature;
+ for a more detailed description refer to doc/README.update.
+
+- MTD Support (mtdparts command, UBI support)
+ CONFIG_MTD_UBI_WL_THRESHOLD
+ This parameter defines the maximum difference between the highest
+ erase counter value and the lowest erase counter value of eraseblocks
+ of UBI devices. When this threshold is exceeded, UBI starts performing
+ wear leveling by means of moving data from eraseblock with low erase
+ counter to eraseblocks with high erase counter.
+
+ The default value should be OK for SLC NAND flashes, NOR flashes and
+ other flashes which have eraseblock life-cycle 100000 or more.
+ However, in case of MLC NAND flashes which typically have eraseblock
+ life-cycle less than 10000, the threshold should be lessened (e.g.,
+ to 128 or 256, although it does not have to be power of 2).
+
+ default: 4096
+
+ CONFIG_MTD_UBI_BEB_LIMIT
+ This option specifies the maximum bad physical eraseblocks UBI
+ expects on the MTD device (per 1024 eraseblocks). If the
+ underlying flash does not admit of bad eraseblocks (e.g. NOR
+ flash), this value is ignored.
+
+ NAND datasheets often specify the minimum and maximum NVM
+ (Number of Valid Blocks) for the flashes' endurance lifetime.
+ The maximum expected bad eraseblocks per 1024 eraseblocks
+ then can be calculated as "1024 * (1 - MinNVB / MaxNVB)",
+ which gives 20 for most NANDs (MaxNVB is basically the total
+ count of eraseblocks on the chip).
+
+ To put it differently, if this value is 20, UBI will try to
+ reserve about 1.9% of physical eraseblocks for bad blocks
+ handling. And that will be 1.9% of eraseblocks on the entire
+ NAND chip, not just the MTD partition UBI attaches. This means
+ that if you have, say, a NAND flash chip admits maximum 40 bad
+ eraseblocks, and it is split on two MTD partitions of the same
+ size, UBI will reserve 40 eraseblocks when attaching a
+ partition.
+
+ default: 20
+
+ CONFIG_MTD_UBI_FASTMAP
+ Fastmap is a mechanism which allows attaching an UBI device
+ in nearly constant time. Instead of scanning the whole MTD device it
+ only has to locate a checkpoint (called fastmap) on the device.
+ The on-flash fastmap contains all information needed to attach
+ the device. Using fastmap makes only sense on large devices where
+ attaching by scanning takes long. UBI will not automatically install
+ a fastmap on old images, but you can set the UBI parameter
+ CONFIG_MTD_UBI_FASTMAP_AUTOCONVERT to 1 if you want so. Please note
+ that fastmap-enabled images are still usable with UBI implementations
+ without fastmap support. On typical flash devices the whole fastmap
+ fits into one PEB. UBI will reserve PEBs to hold two fastmaps.
+
+ CONFIG_MTD_UBI_FASTMAP_AUTOCONVERT
+ Set this parameter to enable fastmap automatically on images
+ without a fastmap.
+ default: 0
+
+ CONFIG_MTD_UBI_FM_DEBUG
+ Enable UBI fastmap debug
+ default: 0
+
+- SPL framework
+ CONFIG_SPL
+ Enable building of SPL globally.
+
+ CONFIG_SPL_LDSCRIPT
+ LDSCRIPT for linking the SPL binary.
+
+ CONFIG_SPL_MAX_FOOTPRINT
+ Maximum size in memory allocated to the SPL, BSS included.
+ When defined, the linker checks that the actual memory
+ used by SPL from _start to __bss_end does not exceed it.
+ CONFIG_SPL_MAX_FOOTPRINT and CONFIG_SPL_BSS_MAX_SIZE
+ must not be both defined at the same time.
+
+ CONFIG_SPL_MAX_SIZE
+ Maximum size of the SPL image (text, data, rodata, and
+ linker lists sections), BSS excluded.
+ When defined, the linker checks that the actual size does
+ not exceed it.
+
+ CONFIG_SPL_TEXT_BASE
+ TEXT_BASE for linking the SPL binary.
+
+ CONFIG_SPL_RELOC_TEXT_BASE
+ Address to relocate to. If unspecified, this is equal to
+ CONFIG_SPL_TEXT_BASE (i.e. no relocation is done).
+
+ CONFIG_SPL_BSS_START_ADDR
+ Link address for the BSS within the SPL binary.
+
+ CONFIG_SPL_BSS_MAX_SIZE
+ Maximum size in memory allocated to the SPL BSS.
+ When defined, the linker checks that the actual memory used
+ by SPL from __bss_start to __bss_end does not exceed it.
+ CONFIG_SPL_MAX_FOOTPRINT and CONFIG_SPL_BSS_MAX_SIZE
+ must not be both defined at the same time.
+
+ CONFIG_SPL_STACK
+ Adress of the start of the stack SPL will use
+
+ CONFIG_SPL_PANIC_ON_RAW_IMAGE
+ When defined, SPL will panic() if the image it has
+ loaded does not have a signature.
+ Defining this is useful when code which loads images
+ in SPL cannot guarantee that absolutely all read errors
+ will be caught.
+ An example is the LPC32XX MLC NAND driver, which will
+ consider that a completely unreadable NAND block is bad,
+ and thus should be skipped silently.
+
+ CONFIG_SPL_RELOC_STACK
+ Adress of the start of the stack SPL will use after
+ relocation. If unspecified, this is equal to
+ CONFIG_SPL_STACK.
+
+ CONFIG_SYS_SPL_MALLOC_START
+ Starting address of the malloc pool used in SPL.
+ When this option is set the full malloc is used in SPL and
+ it is set up by spl_init() and before that, the simple malloc()
+ can be used if CONFIG_SYS_MALLOC_F is defined.
+
+ CONFIG_SYS_SPL_MALLOC_SIZE
+ The size of the malloc pool used in SPL.
+
+ CONFIG_SPL_OS_BOOT
+ Enable booting directly to an OS from SPL.
+ See also: doc/README.falcon

+ Partition on the MMC to load U-Boot from when the MMC is being
+ used in raw mode
+
+ CONFIG_SYS_MMCSD_RAW_MODE_KERNEL_SECTOR
+ Sector to load kernel uImage from when MMC is being
+ used in raw mode (for Falcon mode)

+ Sector and number of sectors to load kernel argument
+ parameters from when MMC is being used in raw mode
+ (for falcon mode)
+
+ CONFIG_SYS_MMCSD_FS_BOOT_PARTITION
+ Partition on the MMC to load U-Boot from when the MMC is being
+ used in fs mode

+
+ CONFIG_SPL_FS_LOAD_ARGS_NAME
+ Filename to read to load kernel argument parameters
+ when reading from filesystem (for Falcon mode)
+
+ CONFIG_SPL_MPC83XX_WAIT_FOR_NAND
+ Set this for NAND SPL on PPC mpc83xx targets, so that
+ start.S waits for the rest of the SPL to load before
+ continuing (the hardware starts execution after just
+ loading the first page rather than the full 4K).
+
+ CONFIG_SPL_SKIP_RELOCATE
+ Avoid SPL relocation
+
+ CONFIG_SPL_NAND_BASE
+ Include nand_base.c in the SPL. Requires
+ CONFIG_SPL_NAND_DRIVERS.
+
+ CONFIG_SPL_NAND_DRIVERS
+ SPL uses normal NAND drivers, not minimal drivers.
+
+ CONFIG_SPL_NAND_IDENT
+ SPL uses the chip ID list to identify the NAND flash.
+ Requires CONFIG_SPL_NAND_BASE.
+
+ CONFIG_SPL_NAND_ECC
+ Include standard software ECC in the SPL
+
+ CONFIG_SPL_NAND_SIMPLE
+ Support for NAND boot using simple NAND drivers that
+ expose the cmd_ctrl() interface.
+
+ CONFIG_SPL_UBI
+ Support for a lightweight UBI (fastmap) scanner and
+ loader
+
+ CONFIG_SPL_NAND_RAW_ONLY
+ Support to boot only raw u-boot.bin images. Use this only
+ if you need to save space.
+
+ CONFIG_SPL_COMMON_INIT_DDR
+ Set for common ddr init with serial presence detect in
+ SPL binary.
+
+ CONFIG_SYS_NAND_5_ADDR_CYCLE, CONFIG_SYS_NAND_PAGE_COUNT,
+ CONFIG_SYS_NAND_PAGE_SIZE, CONFIG_SYS_NAND_OOBSIZE,
+ CONFIG_SYS_NAND_BLOCK_SIZE, CONFIG_SYS_NAND_BAD_BLOCK_POS,
+ CONFIG_SYS_NAND_ECCPOS, CONFIG_SYS_NAND_ECCSIZE,
+ CONFIG_SYS_NAND_ECCBYTES
+ Defines the size and behavior of the NAND that SPL uses
+ to read U-Boot
+
+ CONFIG_SPL_NAND_BOOT
+ Add support NAND boot
+
+ CONFIG_SYS_NAND_U_BOOT_OFFS
+ Location in NAND to read U-Boot from
+
+ CONFIG_SYS_NAND_U_BOOT_DST
+ Location in memory to load U-Boot to
+
+ CONFIG_SYS_NAND_U_BOOT_SIZE
+ Size of image to load
+
+ CONFIG_SYS_NAND_U_BOOT_START
+ Entry point in loaded image to jump to
+
+ CONFIG_SYS_NAND_HW_ECC_OOBFIRST
+ Define this if you need to first read the OOB and then the
+ data. This is used, for example, on davinci platforms.
+
+ CONFIG_SPL_RAM_DEVICE
+ Support for running image already present in ram, in SPL binary
+
+ CONFIG_SPL_PAD_TO
+ Image offset to which the SPL should be padded before appending
+ the SPL payload. By default, this is defined as
+ CONFIG_SPL_MAX_SIZE, or 0 if CONFIG_SPL_MAX_SIZE is undefined.
+ CONFIG_SPL_PAD_TO must be either 0, meaning to append the SPL
+ payload without any padding, or >= CONFIG_SPL_MAX_SIZE.
+
+ CONFIG_SPL_TARGET
+ Final target image containing SPL and payload. Some SPLs
+ use an arch-specific makefile fragment instead, for
+ example if more than one image needs to be produced.
+
+ CONFIG_SPL_FIT_PRINT
+ Printing information about a FIT image adds quite a bit of
+ code to SPL. So this is normally disabled in SPL. Use this
+ option to re-enable it. This will affect the output of the
+ bootm command when booting a FIT image.
+
+- TPL framework
+ CONFIG_TPL
+ Enable building of TPL globally.
+
+ CONFIG_TPL_PAD_TO
+ Image offset to which the TPL should be padded before appending
+ the TPL payload. By default, this is defined as
+ CONFIG_SPL_MAX_SIZE, or 0 if CONFIG_SPL_MAX_SIZE is undefined.
+ CONFIG_SPL_PAD_TO must be either 0, meaning to append the SPL
+ payload without any padding, or >= CONFIG_SPL_MAX_SIZE.
+
+- Interrupt support (PPC):
+
+ There are common interrupt_init() and timer_interrupt()
+ for all PPC archs. interrupt_init() calls interrupt_init_cpu()
+ for CPU specific initialization. interrupt_init_cpu()
+ should set decrementer_count to appropriate value. If
+ CPU resets decrementer automatically after interrupt
+ (ppc4xx) it should set decrementer_count to zero.
+ timer_interrupt() calls timer_interrupt_cpu() for CPU
+ specific handling. If board has watchdog / status_led
+ / other_activity_monitor it works automatically from
+ general timer_interrupt().
+
+
+Board initialization settings:
+------------------------------
+
+During Initialization u-boot calls a number of board specific functions
+to allow the preparation of board specific prerequisites, e.g. pin setup
+before drivers are initialized. To enable these callbacks the
+following configuration macros have to be defined. Currently this is
+architecture specific, so please check arch/your_architecture/lib/board.c
+typically in board_init_f() and board_init_r().
+
+- CONFIG_BOARD_EARLY_INIT_F: Call board_early_init_f()
+- CONFIG_BOARD_EARLY_INIT_R: Call board_early_init_r()
+- CONFIG_BOARD_LATE_INIT: Call board_late_init()
+- CONFIG_BOARD_POSTCLK_INIT: Call board_postclk_init()
+
+Configuration Settings:
+-----------------------
+
+- CONFIG_SYS_SUPPORT_64BIT_DATA: Defined automatically if compiled as 64-bit.
+ Optionally it can be defined to support 64-bit memory commands.
+
+- CONFIG_SYS_LONGHELP: Defined when you want long help messages included;
+ undefine this when you're short of memory.
+
+- CONFIG_SYS_HELP_CMD_WIDTH: Defined when you want to override the default
+ width of the commands listed in the 'help' command output.
+
+- CONFIG_SYS_PROMPT: This is what U-Boot prints on the console to
+ prompt for user input.
+
+- CONFIG_SYS_CBSIZE: Buffer size for input from the Console
+
+- CONFIG_SYS_PBSIZE: Buffer size for Console output
+
+- CONFIG_SYS_MAXARGS: max. Number of arguments accepted for monitor commands
+
+- CONFIG_SYS_BARGSIZE: Buffer size for Boot Arguments which are passed to
+ the application (usually a Linux kernel) when it is
+ booted
+
+- CONFIG_SYS_BAUDRATE_TABLE:
+ List of legal baudrate settings for this board.
+
+- CONFIG_SYS_MEMTEST_START, CONFIG_SYS_MEMTEST_END:
+ Begin and End addresses of the area used by the
+ simple memory test.
+
+- CONFIG_SYS_MEMTEST_SCRATCH:
+ Scratch address used by the alternate memory test
+ You only need to set this if address zero isn't writeable
+
+- CONFIG_SYS_MEM_RESERVE_SECURE
+ Only implemented for ARMv8 for now.
+ If defined, the size of CONFIG_SYS_MEM_RESERVE_SECURE memory
+ is substracted from total RAM and won't be reported to OS.
+ This memory can be used as secure memory. A variable
+ gd->arch.secure_ram is used to track the location. In systems
+ the RAM base is not zero, or RAM is divided into banks,
+ this variable needs to be recalcuated to get the address.
+
+- CONFIG_SYS_MEM_TOP_HIDE:
+ If CONFIG_SYS_MEM_TOP_HIDE is defined in the board config header,
+ this specified memory area will get subtracted from the top
+ (end) of RAM and won't get "touched" at all by U-Boot. By
+ fixing up gd->ram_size the Linux kernel should gets passed
+ the now "corrected" memory size and won't touch it either.
+ This should work for arch/ppc and arch/powerpc. Only Linux
+ board ports in arch/powerpc with bootwrapper support that
+ recalculate the memory size from the SDRAM controller setup
+ will have to get fixed in Linux additionally.
+
+ This option can be used as a workaround for the 440EPx/GRx
+ CHIP 11 errata where the last 256 bytes in SDRAM shouldn't
+ be touched.
+
+ WARNING: Please make sure that this value is a multiple of
+ the Linux page size (normally 4k). If this is not the case,
+ then the end address of the Linux memory will be located at a
+ non page size aligned address and this could cause major
+ problems.
+
+- CONFIG_SYS_LOADS_BAUD_CHANGE:
+ Enable temporary baudrate change while serial download
+
+- CONFIG_SYS_SDRAM_BASE:
+ Physical start address of SDRAM. _Must_ be 0 here.
+
+- CONFIG_SYS_FLASH_BASE:
+ Physical start address of Flash memory.
+
+- CONFIG_SYS_MONITOR_BASE:
+ Physical start address of boot monitor code (set by
+ make config files to be same as the text base address
+ (CONFIG_SYS_TEXT_BASE) used when linking) - same as
+ CONFIG_SYS_FLASH_BASE when booting from flash.
+
+- CONFIG_SYS_MONITOR_LEN:
+ Size of memory reserved for monitor code, used to
+ determine _at_compile_time_ (!) if the environment is
+ embedded within the U-Boot image, or in a separate
+ flash sector.
+
+- CONFIG_SYS_MALLOC_LEN:
+ Size of DRAM reserved for malloc() use.
+
+- CONFIG_SYS_MALLOC_F_LEN
+ Size of the malloc() pool for use before relocation. If
+ this is defined, then a very simple malloc() implementation
+ will become available before relocation. The address is just
+ below the global data, and the stack is moved down to make
+ space.
+
+ This feature allocates regions with increasing addresses
+ within the region. calloc() is supported, but realloc()
+ is not available. free() is supported but does nothing.
+ The memory will be freed (or in fact just forgotten) when
+ U-Boot relocates itself.
+
+- CONFIG_SYS_MALLOC_SIMPLE
+ Provides a simple and small malloc() and calloc() for those
+ boards which do not use the full malloc in SPL (which is
+ enabled with CONFIG_SYS_SPL_MALLOC_START).
+
+- CONFIG_SYS_NONCACHED_MEMORY:
+ Size of non-cached memory area. This area of memory will be
+ typically located right below the malloc() area and mapped
+ uncached in the MMU. This is useful for drivers that would
+ otherwise require a lot of explicit cache maintenance. For
+ some drivers it's also impossible to properly maintain the
+ cache. For example if the regions that need to be flushed
+ are not a multiple of the cache-line size, *and* padding
+ cannot be allocated between the regions to align them (i.e.
+ if the HW requires a contiguous array of regions, and the
+ size of each region is not cache-aligned), then a flush of
+ one region may result in overwriting data that hardware has
+ written to another region in the same cache-line. This can
+ happen for example in network drivers where descriptors for
+ buffers are typically smaller than the CPU cache-line (e.g.
+ 16 bytes vs. 32 or 64 bytes).
+
+ Non-cached memory is only supported on 32-bit ARM at present.
+
+- CONFIG_SYS_BOOTM_LEN:
+ Normally compressed uImages are limited to an
+ uncompressed size of 8 MBytes. If this is not enough,
+ you can define CONFIG_SYS_BOOTM_LEN in your board config file
+ to adjust this setting to your needs.
+
+- CONFIG_SYS_BOOTMAPSZ:
+ Maximum size of memory mapped by the startup code of
+ the Linux kernel; all data that must be processed by
+ the Linux kernel (bd_info, boot arguments, FDT blob if
+ used) must be put below this limit, unless "bootm_low"
+ environment variable is defined and non-zero. In such case
+ all data for the Linux kernel must be between "bootm_low"
+ and "bootm_low" + CONFIG_SYS_BOOTMAPSZ. The environment
+ variable "bootm_mapsize" will override the value of
+ CONFIG_SYS_BOOTMAPSZ. If CONFIG_SYS_BOOTMAPSZ is undefined,
+ then the value in "bootm_size" will be used instead.
+
+- CONFIG_SYS_BOOT_RAMDISK_HIGH:
+ Enable initrd_high functionality. If defined then the
+ initrd_high feature is enabled and the bootm ramdisk subcommand
+ is enabled.
+
+- CONFIG_SYS_BOOT_GET_CMDLINE:
+ Enables allocating and saving kernel cmdline in space between
+ "bootm_low" and "bootm_low" + BOOTMAPSZ.
+
+- CONFIG_SYS_BOOT_GET_KBD:
+ Enables allocating and saving a kernel copy of the bd_info in
+ space between "bootm_low" and "bootm_low" + BOOTMAPSZ.
+
+- CONFIG_SYS_MAX_FLASH_BANKS:
+ Max number of Flash memory banks
+
+- CONFIG_SYS_MAX_FLASH_SECT:
+ Max number of sectors on a Flash chip
+
+- CONFIG_SYS_FLASH_ERASE_TOUT:
+ Timeout for Flash erase operations (in ms)
+
+- CONFIG_SYS_FLASH_WRITE_TOUT:
+ Timeout for Flash write operations (in ms)
+
+- CONFIG_SYS_FLASH_LOCK_TOUT
+ Timeout for Flash set sector lock bit operation (in ms)
+
+- CONFIG_SYS_FLASH_UNLOCK_TOUT
+ Timeout for Flash clear lock bits operation (in ms)
+
+- CONFIG_SYS_FLASH_PROTECTION
+ If defined, hardware flash sectors protection is used
+ instead of U-Boot software protection.
+
+- CONFIG_SYS_DIRECT_FLASH_TFTP:
+
+ Enable TFTP transfers directly to flash memory;
+ without this option such a download has to be
+ performed in two steps: (1) download to RAM, and (2)
+ copy from RAM to flash.
+
+ The two-step approach is usually more reliable, since
+ you can check if the download worked before you erase
+ the flash, but in some situations (when system RAM is
+ too limited to allow for a temporary copy of the
+ downloaded image) this option may be very useful.
+
+- CONFIG_SYS_FLASH_CFI:
+ Define if the flash driver uses extra elements in the
+ common flash structure for storing flash geometry.
+
+- CONFIG_FLASH_CFI_DRIVER
+ This option also enables the building of the cfi_flash driver
+ in the drivers directory
+
+- CONFIG_FLASH_CFI_MTD
+ This option enables the building of the cfi_mtd driver
+ in the drivers directory. The driver exports CFI flash
+ to the MTD layer.
+
+- CONFIG_SYS_FLASH_USE_BUFFER_WRITE
+ Use buffered writes to flash.
+
+- CONFIG_FLASH_SPANSION_S29WS_N
+ s29ws-n MirrorBit flash has non-standard addresses for buffered
+ write commands.
+
+- CONFIG_SYS_FLASH_QUIET_TEST
+ If this option is defined, the common CFI flash doesn't
+ print it's warning upon not recognized FLASH banks. This
+ is useful, if some of the configured banks are only
+ optionally available.
+
+- CONFIG_FLASH_SHOW_PROGRESS
+ If defined (must be an integer), print out countdown
+ digits and dots. Recommended value: 45 (9..1) for 80
+ column displays, 15 (3..1) for 40 column displays.
+
+- CONFIG_FLASH_VERIFY
+ If defined, the content of the flash (destination) is compared
+ against the source after the write operation. An error message
+ will be printed when the contents are not identical.
+ Please note that this option is useless in nearly all cases,
+ since such flash programming errors usually are detected earlier
+ while unprotecting/erasing/programming. Please only enable
+ this option if you really know what you are doing.
+
+- CONFIG_SYS_RX_ETH_BUFFER:
+ Defines the number of Ethernet receive buffers. On some
+ Ethernet controllers it is recommended to set this value
+ to 8 or even higher (EEPRO100 or 405 EMAC), since all
+ buffers can be full shortly after enabling the interface
+ on high Ethernet traffic.
+ Defaults to 4 if not defined.
+
+- CONFIG_ENV_MAX_ENTRIES
+
+ Maximum number of entries in the hash table that is used
+ internally to store the environment settings. The default
+ setting is supposed to be generous and should work in most
+ cases. This setting can be used to tune behaviour; see
+ lib/hashtable.c for details.
+
+- CONFIG_ENV_FLAGS_LIST_DEFAULT
+- CONFIG_ENV_FLAGS_LIST_STATIC
+ Enable validation of the values given to environment variables when
+ calling env set. Variables can be restricted to only decimal,
+ hexadecimal, or boolean. If CONFIG_CMD_NET is also defined,
+ the variables can also be restricted to IP address or MAC address.
+
+ The format of the list is:
+ type_attribute = [s|d|x|b|i|m]
+ access_attribute = [a|r|o|c]
+ attributes = type_attribute[access_attribute]
+ entry = variable_name[:attributes]
+ list = entry[,list]
+
+ The type attributes are:
+ s - String (default)
+ d - Decimal
+ x - Hexadecimal
+ b - Boolean ([1yYtT|0nNfF])
+ i - IP address
+ m - MAC address
+
+ The access attributes are:
+ a - Any (default)
+ r - Read-only
+ o - Write-once
+ c - Change-default
+
+ - CONFIG_ENV_FLAGS_LIST_DEFAULT
+ Define this to a list (string) to define the ".flags"
+ environment variable in the default or embedded environment.
+
+ - CONFIG_ENV_FLAGS_LIST_STATIC
+ Define this to a list (string) to define validation that
+ should be done if an entry is not found in the ".flags"
+ environment variable. To override a setting in the static
+ list, simply add an entry for the same variable name to the
+ ".flags" variable.
+
+ If CONFIG_REGEX is defined, the variable_name above is evaluated as a
+ regular expression. This allows multiple variables to define the same
+ flags without explicitly listing them for each variable.
+
+- CONFIG_ENV_ACCESS_IGNORE_FORCE
+ If defined, don't allow the -f switch to env set override variable
+ access flags.
+
+The following definitions that deal with the placement and management
+of environment data (variable area); in general, we support the
+following configurations:
+
+- CONFIG_BUILD_ENVCRC:
+
+ Builds up envcrc with the target environment so that external utils
+ may easily extract it and embed it in final U-Boot images.
+
+BE CAREFUL! The first access to the environment happens quite early
+in U-Boot initialization (when we try to get the setting of for the
+console baudrate). You *MUST* have mapped your NVRAM area then, or
+U-Boot will hang.
+
+Please note that even with NVRAM we still use a copy of the
+environment in RAM: we could work on NVRAM directly, but we want to
+keep settings there always unmodified except somebody uses "saveenv"
+to save the current settings.
+
+BE CAREFUL! For some special cases, the local device can not use
+"saveenv" command. For example, the local device will get the
+environment stored in a remote NOR flash by SRIO or PCIE link,
+but it can not erase, write this NOR flash by SRIO or PCIE interface.
+
+- CONFIG_NAND_ENV_DST
+
+ Defines address in RAM to which the nand_spl code should copy the
+ environment. If redundant environment is used, it will be copied to
+ CONFIG_NAND_ENV_DST + CONFIG_ENV_SIZE.
+
+Please note that the environment is read-only until the monitor
+has been relocated to RAM and a RAM copy of the environment has been
+created; also, when using EEPROM you will have to use env_get_f()
+until then to read environment variables.
+
+The environment is protected by a CRC32 checksum. Before the monitor
+is relocated into RAM, as a result of a bad CRC you will be working
+with the compiled-in default environment - *silently*!!! [This is
+necessary, because the first environment variable we need is the
+"baudrate" setting for the console - if we have a bad CRC, we don't
+have any device yet where we could complain.]
+
+Note: once the monitor has been relocated, then it will complain if
+the default environment is used; a new CRC is computed as soon as you
+use the "saveenv" command to store a valid environment.
+
+- CONFIG_SYS_FAULT_ECHO_LINK_DOWN:
+ Echo the inverted Ethernet link state to the fault LED.
+
+ Note: If this option is active, then CONFIG_SYS_FAULT_MII_ADDR
+ also needs to be defined.
+
+- CONFIG_SYS_FAULT_MII_ADDR:
+ MII address of the PHY to check for the Ethernet link state.
+
+- CONFIG_NS16550_MIN_FUNCTIONS:
+ Define this if you desire to only have use of the NS16550_init
+ and NS16550_putc functions for the serial driver located at
+ drivers/serial/ns16550.c. This option is useful for saving
+ space for already greatly restricted images, including but not
+ limited to NAND_SPL configurations.
+
+- CONFIG_DISPLAY_BOARDINFO
+ Display information about the board that U-Boot is running on
+ when U-Boot starts up. The board function checkboard() is called
+ to do this.
+
+- CONFIG_DISPLAY_BOARDINFO_LATE
+ Similar to the previous option, but display this information
+ later, once stdio is running and output goes to the LCD, if
+ present.
+
+- CONFIG_BOARD_SIZE_LIMIT:
+ Maximum size of the U-Boot image. When defined, the
+ build system checks that the actual size does not
+ exceed it.
+
+Low Level (hardware related) configuration options:
+---------------------------------------------------
+
+- CONFIG_SYS_CACHELINE_SIZE:
+ Cache Line Size of the CPU.
+
+- CONFIG_SYS_CCSRBAR_DEFAULT:
+ Default (power-on reset) physical address of CCSR on Freescale
+ PowerPC SOCs.
+
+- CONFIG_SYS_CCSRBAR:
+ Virtual address of CCSR. On a 32-bit build, this is typically
+ the same value as CONFIG_SYS_CCSRBAR_DEFAULT.
+
+- CONFIG_SYS_CCSRBAR_PHYS:
+ Physical address of CCSR. CCSR can be relocated to a new
+ physical address, if desired. In this case, this macro should
+ be set to that address. Otherwise, it should be set to the
+ same value as CONFIG_SYS_CCSRBAR_DEFAULT. For example, CCSR
+ is typically relocated on 36-bit builds. It is recommended
+ that this macro be defined via the _HIGH and _LOW macros:
+
+ #define CONFIG_SYS_CCSRBAR_PHYS ((CONFIG_SYS_CCSRBAR_PHYS_HIGH
+ * 1ull) << 32 | CONFIG_SYS_CCSRBAR_PHYS_LOW)
+
+- CONFIG_SYS_CCSRBAR_PHYS_HIGH:
+ Bits 33-36 of CONFIG_SYS_CCSRBAR_PHYS. This value is typically
+ either 0 (32-bit build) or 0xF (36-bit build). This macro is
+ used in assembly code, so it must not contain typecasts or
+ integer size suffixes (e.g. "ULL").
+
+- CONFIG_SYS_CCSRBAR_PHYS_LOW:
+ Lower 32-bits of CONFIG_SYS_CCSRBAR_PHYS. This macro is
+ used in assembly code, so it must not contain typecasts or
+ integer size suffixes (e.g. "ULL").
+
+- CONFIG_SYS_CCSR_DO_NOT_RELOCATE:
+ If this macro is defined, then CONFIG_SYS_CCSRBAR_PHYS will be
+ forced to a value that ensures that CCSR is not relocated.
+
+- Floppy Disk Support:
+ CONFIG_SYS_FDC_DRIVE_NUMBER
+
+ the default drive number (default value 0)
+
+ CONFIG_SYS_ISA_IO_STRIDE
+
+ defines the spacing between FDC chipset registers
+ (default value 1)
+
+ CONFIG_SYS_ISA_IO_OFFSET
+
+ defines the offset of register from address. It
+ depends on which part of the data bus is connected to
+ the FDC chipset. (default value 0)
+
+ If CONFIG_SYS_ISA_IO_STRIDE CONFIG_SYS_ISA_IO_OFFSET and
+ CONFIG_SYS_FDC_DRIVE_NUMBER are undefined, they take their
+ default value.
+
+ if CONFIG_SYS_FDC_HW_INIT is defined, then the function
+ fdc_hw_init() is called at the beginning of the FDC
+ setup. fdc_hw_init() must be provided by the board
+ source code. It is used to make hardware-dependent
+ initializations.
+
+- CONFIG_IDE_AHB:
+ Most IDE controllers were designed to be connected with PCI
+ interface. Only few of them were designed for AHB interface.
+ When software is doing ATA command and data transfer to
+ IDE devices through IDE-AHB controller, some additional
+ registers accessing to these kind of IDE-AHB controller
+ is required.
+
+- CONFIG_SYS_IMMR: Physical address of the Internal Memory.
+ DO NOT CHANGE unless you know exactly what you're
+ doing! (11-4) [MPC8xx systems only]
+
+- CONFIG_SYS_INIT_RAM_ADDR:
+
+ Start address of memory area that can be used for
+ initial data and stack; please note that this must be
+ writable memory that is working WITHOUT special
+ initialization, i. e. you CANNOT use normal RAM which
+ will become available only after programming the
+ memory controller and running certain initialization
+ sequences.
+
+ U-Boot uses the following memory types:
+ - MPC8xx: IMMR (internal memory of the CPU)
+
+- CONFIG_SYS_GBL_DATA_OFFSET:
+
+ Offset of the initial data structure in the memory
+ area defined by CONFIG_SYS_INIT_RAM_ADDR. Usually
+ CONFIG_SYS_GBL_DATA_OFFSET is chosen such that the initial
+ data is located at the end of the available space
+ (sometimes written as (CONFIG_SYS_INIT_RAM_SIZE -
+ GENERATED_GBL_DATA_SIZE), and the initial stack is just
+ below that area (growing from (CONFIG_SYS_INIT_RAM_ADDR +
+ CONFIG_SYS_GBL_DATA_OFFSET) downward.
+
+ Note:
+ On the MPC824X (or other systems that use the data
+ cache for initial memory) the address chosen for
+ CONFIG_SYS_INIT_RAM_ADDR is basically arbitrary - it must
+ point to an otherwise UNUSED address space between
+ the top of RAM and the start of the PCI space.
+
+- CONFIG_SYS_SCCR: System Clock and reset Control Register (15-27)
+
+- CONFIG_SYS_OR_TIMING_SDRAM:
+ SDRAM timing
+
+- CONFIG_SYS_MAMR_PTA:
+ periodic timer for refresh
+
+- FLASH_BASE0_PRELIM, FLASH_BASE1_PRELIM, CONFIG_SYS_REMAP_OR_AM,
+ CONFIG_SYS_PRELIM_OR_AM, CONFIG_SYS_OR_TIMING_FLASH, CONFIG_SYS_OR0_REMAP,
+ CONFIG_SYS_OR0_PRELIM, CONFIG_SYS_BR0_PRELIM, CONFIG_SYS_OR1_REMAP, CONFIG_SYS_OR1_PRELIM,
+ CONFIG_SYS_BR1_PRELIM:
+ Memory Controller Definitions: BR0/1 and OR0/1 (FLASH)
+
+- SDRAM_BASE2_PRELIM, SDRAM_BASE3_PRELIM, SDRAM_MAX_SIZE,
+ CONFIG_SYS_OR_TIMING_SDRAM, CONFIG_SYS_OR2_PRELIM, CONFIG_SYS_BR2_PRELIM,
+ CONFIG_SYS_OR3_PRELIM, CONFIG_SYS_BR3_PRELIM:
+ Memory Controller Definitions: BR2/3 and OR2/3 (SDRAM)
+
+- CONFIG_PCI_ENUM_ONLY
+ Only scan through and get the devices on the buses.
+ Don't do any setup work, presumably because someone or
+ something has already done it, and we don't need to do it
+ a second time. Useful for platforms that are pre-booted
+ by coreboot or similar.
+
+- CONFIG_PCI_INDIRECT_BRIDGE:
+ Enable support for indirect PCI bridges.
+
+- CONFIG_SYS_SRIO:
+ Chip has SRIO or not
+
+- CONFIG_SRIO1:
+ Board has SRIO 1 port available
+
+- CONFIG_SRIO2:
+ Board has SRIO 2 port available
+

+ Board can support master function for Boot from SRIO and PCIE
+
+- CONFIG_SYS_SRIOn_MEM_VIRT:
+ Virtual Address of SRIO port 'n' memory region
+
+- CONFIG_SYS_SRIOn_MEM_PHYS:
+ Physical Address of SRIO port 'n' memory region
+
+- CONFIG_SYS_SRIOn_MEM_SIZE:
+ Size of SRIO port 'n' memory region
+
+- CONFIG_SYS_NAND_BUSWIDTH_16BIT
+ Defined to tell the NAND controller that the NAND chip is using
+ a 16 bit bus.
+ Not all NAND drivers use this symbol.
+ Example of drivers that use it:
+ - drivers/mtd/nand/raw/ndfc.c
+ - drivers/mtd/nand/raw/mxc_nand.c
+
+- CONFIG_SYS_NDFC_EBC0_CFG
+ Sets the EBC0_CFG register for the NDFC. If not defined
+ a default value will be used.
+
+- CONFIG_SPD_EEPROM
+ Get DDR timing information from an I2C EEPROM. Common
+ with pluggable memory modules such as SODIMMs
+
+ SPD_EEPROM_ADDRESS
+ I2C address of the SPD EEPROM
+
+- CONFIG_SYS_SPD_BUS_NUM
+ If SPD EEPROM is on an I2C bus other than the first
+ one, specify here. Note that the value must resolve
+ to something your driver can deal with.
+
+- CONFIG_SYS_DDR_RAW_TIMING
+ Get DDR timing information from other than SPD. Common with
+ soldered DDR chips onboard without SPD. DDR raw timing
+ parameters are extracted from datasheet and hard-coded into
+ header files or board specific files.
+
+- CONFIG_FSL_DDR_INTERACTIVE
+ Enable interactive DDR debugging. See doc/README.fsl-ddr.
+
+- CONFIG_FSL_DDR_SYNC_REFRESH
+ Enable sync of refresh for multiple controllers.
+
+- CONFIG_FSL_DDR_BIST
+ Enable built-in memory test for Freescale DDR controllers.
+
+- CONFIG_SYS_83XX_DDR_USES_CS0
+ Only for 83xx systems. If specified, then DDR should
+ be configured using CS0 and CS1 instead of CS2 and CS3.
+
+- CONFIG_RMII
+ Enable RMII mode for all FECs.
+ Note that this is a global option, we can't
+ have one FEC in standard MII mode and another in RMII mode.
+
+- CONFIG_CRC32_VERIFY
+ Add a verify option to the crc32 command.
+ The syntax is:
+
+ => crc32 -v <address> <count> <crc32>
+
+ Where address/count indicate a memory area
+ and crc32 is the correct crc32 which the
+ area should have.
+
+- CONFIG_LOOPW
+ Add the "loopw" memory command. This only takes effect if
+ the memory commands are activated globally (CONFIG_CMD_MEMORY).
+
+- CONFIG_MX_CYCLIC
+ Add the "mdc" and "mwc" memory commands. These are cyclic
+ "md/mw" commands.
+ Examples:
+
+ => mdc.b 10 4 500
+ This command will print 4 bytes (10,11,12,13) each 500 ms.
+
+ => mwc.l 100 12345678 10
+ This command will write 12345678 to address 100 all 10 ms.
+
+ This only takes effect if the memory commands are activated
+ globally (CONFIG_CMD_MEMORY).
+
+- CONFIG_SKIP_LOWLEVEL_INIT
+ [ARM, NDS32, MIPS, RISC-V only] If this variable is defined, then certain
+ low level initializations (like setting up the memory
+ controller) are omitted and/or U-Boot does not
+ relocate itself into RAM.
+
+ Normally this variable MUST NOT be defined. The only
+ exception is when U-Boot is loaded (to RAM) by some
+ other boot loader or by a debugger which performs
+ these initializations itself.
+
+- CONFIG_SKIP_LOWLEVEL_INIT_ONLY
+ [ARM926EJ-S only] This allows just the call to lowlevel_init()
+ to be skipped. The normal CP15 init (such as enabling the
+ instruction cache) is still performed.
+
+- CONFIG_SPL_BUILD
+ Modifies the behaviour of start.S when compiling a loader
+ that is executed before the actual U-Boot. E.g. when
+ compiling a NAND SPL.
+
+- CONFIG_TPL_BUILD
+ Modifies the behaviour of start.S when compiling a loader
+ that is executed after the SPL and before the actual U-Boot.
+ It is loaded by the SPL.
+
+- CONFIG_SYS_MPC85XX_NO_RESETVEC
+ Only for 85xx systems. If this variable is specified, the section
+ .resetvec is not kept and the section .bootpg is placed in the
+ previous 4k of the .text section.
+
+- CONFIG_ARCH_MAP_SYSMEM
+ Generally U-Boot (and in particular the md command) uses
+ effective address. It is therefore not necessary to regard
+ U-Boot address as virtual addresses that need to be translated
+ to physical addresses. However, sandbox requires this, since
+ it maintains its own little RAM buffer which contains all
+ addressable memory. This option causes some memory accesses
+ to be mapped through map_sysmem() / unmap_sysmem().
+
+- CONFIG_X86_RESET_VECTOR
+ If defined, the x86 reset vector code is included. This is not
+ needed when U-Boot is running from Coreboot.
+
+- CONFIG_SYS_NAND_NO_SUBPAGE_WRITE
+ Option to disable subpage write in NAND driver
+ driver that uses this:
+ drivers/mtd/nand/raw/davinci_nand.c
+
+Freescale QE/FMAN Firmware Support:
+-----------------------------------
+
+The Freescale QUICCEngine (QE) and Frame Manager (FMAN) both support the
+loading of "firmware", which is encoded in the QE firmware binary format.
+This firmware often needs to be loaded during U-Boot booting, so macros
+are used to identify the storage device (NOR flash, SPI, etc) and the address
+within that device.
+
+- CONFIG_SYS_FMAN_FW_ADDR
+ The address in the storage device where the FMAN microcode is located. The
+ meaning of this address depends on which CONFIG_SYS_QE_FW_IN_xxx macro
+ is also specified.
+
+- CONFIG_SYS_QE_FW_ADDR
+ The address in the storage device where the QE microcode is located. The
+ meaning of this address depends on which CONFIG_SYS_QE_FW_IN_xxx macro
+ is also specified.
+
+- CONFIG_SYS_QE_FMAN_FW_LENGTH
+ The maximum possible size of the firmware. The firmware binary format
+ has a field that specifies the actual size of the firmware, but it
+ might not be possible to read any part of the firmware unless some
+ local storage is allocated to hold the entire firmware first.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_NOR
+ Specifies that QE/FMAN firmware is located in NOR flash, mapped as
+ normal addressable memory via the LBC. CONFIG_SYS_FMAN_FW_ADDR is the
+ virtual address in NOR flash.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_NAND
+ Specifies that QE/FMAN firmware is located in NAND flash.
+ CONFIG_SYS_FMAN_FW_ADDR is the offset within NAND flash.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_MMC
+ Specifies that QE/FMAN firmware is located on the primary SD/MMC
+ device. CONFIG_SYS_FMAN_FW_ADDR is the byte offset on that device.
+
+- CONFIG_SYS_QE_FMAN_FW_IN_REMOTE
+ Specifies that QE/FMAN firmware is located in the remote (master)
+ memory space. CONFIG_SYS_FMAN_FW_ADDR is a virtual address which
+ can be mapped from slave TLB->slave LAW->slave SRIO or PCIE outbound
+ window->master inbound window->master LAW->the ucode address in
+ master's memory space.
+
+Freescale Layerscape Management Complex Firmware Support:
+---------------------------------------------------------
+The Freescale Layerscape Management Complex (MC) supports the loading of
+"firmware".
+This firmware often needs to be loaded during U-Boot booting, so macros
+are used to identify the storage device (NOR flash, SPI, etc) and the address
+within that device.
+
+- CONFIG_FSL_MC_ENET
+ Enable the MC driver for Layerscape SoCs.
+
+Freescale Layerscape Debug Server Support:
+-------------------------------------------
+The Freescale Layerscape Debug Server Support supports the loading of
+"Debug Server firmware" and triggering SP boot-rom.
+This firmware often needs to be loaded during U-Boot booting.
+
+- CONFIG_SYS_MC_RSV_MEM_ALIGN
+ Define alignment of reserved memory MC requires
+
+Reproducible builds
+-------------------
+
+In order to achieve reproducible builds, timestamps used in the U-Boot build
+process have to be set to a fixed value.
+
+This is done using the SOURCE_DATE_EPOCH environment variable.
+SOURCE_DATE_EPOCH is to be set on the build host's shell, not as a configuration
+option for U-Boot or an environment variable in U-Boot.
+
+SOURCE_DATE_EPOCH should be set to a number of seconds since the epoch, in UTC.
+
+Building the Software:
+======================
+
+Building U-Boot has been tested in several native build environments
+and in many different cross environments. Of course we cannot support
+all possibly existing versions of cross development tools in all
+(potentially obsolete) versions. In case of tool chain problems we
+recommend to use the ELDK (see http://www.denx.de/wiki/DULG/ELDK)
+which is extensively used to build and test U-Boot.
+
+If you are not using a native environment, it is assumed that you
+have GNU cross compiling tools available in your path. In this case,
+you must set the environment variable CROSS_COMPILE in your shell.
+Note that no changes to the Makefile or any other source files are
+necessary. For example using the ELDK on a 4xx CPU, please enter:
+
+ $ CROSS_COMPILE=ppc_4xx-
+ $ export CROSS_COMPILE
+
+Note: If you wish to generate Windows versions of the utilities in
+ the tools directory you can use the MinGW toolchain
+ (http://www.mingw.org). Set your HOST tools to the MinGW
+ toolchain and execute 'make tools'. For example:
+
+ $ make HOSTCC=i586-mingw32msvc-gcc HOSTSTRIP=i586-mingw32msvc-strip tools
+
+ Binaries such as tools/mkimage.exe will be created which can
+ be executed on computers running Windows.
+
+U-Boot is intended to be simple to build. After installing the
+sources you must configure U-Boot for one specific board type. This
+is done by typing:
+
+ make NAME_defconfig
+
+where "NAME_defconfig" is the name of one of the existing configu-
+rations; see boards.cfg for supported names.
+
+Note: for some board special configuration names may exist; check if
+ additional information is available from the board vendor; for
+ instance, the TQM823L systems are available without (standard)
+ or with LCD support. You can select such additional "features"
+ when choosing the configuration, i. e.
+
+ make TQM823L_defconfig
+ - will configure for a plain TQM823L, i. e. no LCD support
+
+ make TQM823L_LCD_defconfig
+ - will configure for a TQM823L with U-Boot console on LCD
+
+ etc.
+
+
+Finally, type "make all", and you should get some working U-Boot
+images ready for download to / installation on your system:
+
+- "u-boot.bin" is a raw binary image
+- "u-boot" is an image in ELF binary format
+- "u-boot.srec" is in Motorola S-Record format
+
+By default the build is performed locally and the objects are saved
+in the source directory. One of the two methods can be used to change
+this behavior and build U-Boot to some external directory:
+
+1. Add O= to the make command line invocations:
+
+ make O=/tmp/build distclean
+ make O=/tmp/build NAME_defconfig
+ make O=/tmp/build all
+
+2. Set environment variable KBUILD_OUTPUT to point to the desired location:
+
+ export KBUILD_OUTPUT=/tmp/build
+ make distclean
+ make NAME_defconfig
+ make all
+
+Note that the command line "O=" setting overrides the KBUILD_OUTPUT environment
+variable.
+
+User specific CPPFLAGS, AFLAGS and CFLAGS can be passed to the compiler by
+setting the according environment variables KCPPFLAGS, KAFLAGS and KCFLAGS.
+For example to treat all compiler warnings as errors:
+
+ make KCFLAGS=-Werror
+
+Please be aware that the Makefiles assume you are using GNU make, so
+for instance on NetBSD you might need to use "gmake" instead of
+native "make".
+
+
+If the system board that you have is not listed, then you will need
+to port U-Boot to your hardware platform. To do this, follow these
+steps:
+
+1. Create a new directory to hold your board specific code. Add any
+ files you need. In your board directory, you will need at least
+ the "Makefile" and a "<board>.c".
+2. Create a new configuration file "include/configs/<board>.h" for
+ your board.
+3. If you're porting U-Boot to a new CPU, then also create a new
+ directory to hold your CPU specific code. Add any files you need.
+4. Run "make <board>_defconfig" with your new name.
+5. Type "make", and you should get a working "u-boot.srec" file
+ to be installed on your target system.
+6. Debug and solve any problems that might arise.
+ [Of course, this last step is much harder than it sounds.]
+
+
+Testing of U-Boot Modifications, Ports to New Hardware, etc.:
+==============================================================
+
+If you have modified U-Boot sources (for instance added a new board
+or support for new devices, a new CPU, etc.) you are expected to
+provide feedback to the other developers. The feedback normally takes
+the form of a "patch", i. e. a context diff against a certain (latest
+official or latest in the git repository) version of U-Boot sources.
+
+But before you submit such a patch, please verify that your modifi-
+cation did not break existing code. At least make sure that *ALL* of
+the supported boards compile WITHOUT ANY compiler warnings. To do so,
+just run the buildman script (tools/buildman/buildman), which will
+configure and build U-Boot for ALL supported system. Be warned, this
+will take a while. Please see the buildman README, or run 'buildman -H'
+for documentation.

+Monitor Commands - Detailed Description:
+========================================
+
+TODO.
+
+For now: just type "help <command>".
+
+
+Environment Variables:
+======================
+
+U-Boot supports user configuration using Environment Variables which
+can be made persistent by saving to Flash memory.
+
+Environment Variables are set using "setenv", printed using
+"printenv", and saved to Flash using "saveenv". Using "setenv"
+without a value can be used to delete a variable from the
+environment. As long as you don't save the environment you are
+working with an in-memory copy. In case the Flash area containing the
+environment is erased by accident, a default environment is provided.
+
+Some configuration options can be set using Environment Variables.
+
+List of environment variables (most likely not complete):
+
+ baudrate - see CONFIG_BAUDRATE
+
+ bootdelay - see CONFIG_BOOTDELAY
+
+ bootcmd - see CONFIG_BOOTCOMMAND
+
+ bootargs - Boot arguments when booting an RTOS image
+
+ bootfile - Name of the image to load with TFTP
+
+ bootm_low - Memory range available for image processing in the bootm
+ command can be restricted. This variable is given as
+ a hexadecimal number and defines lowest address allowed
+ for use by the bootm command. See also "bootm_size"
+ environment variable. Address defined by "bootm_low" is
+ also the base of the initial memory mapping for the Linux
+ kernel -- see the description of CONFIG_SYS_BOOTMAPSZ and
+ bootm_mapsize.
+
+ bootm_mapsize - Size of the initial memory mapping for the Linux kernel.
+ This variable is given as a hexadecimal number and it
+ defines the size of the memory region starting at base
+ address bootm_low that is accessible by the Linux kernel
+ during early boot. If unset, CONFIG_SYS_BOOTMAPSZ is used
+ as the default value if it is defined, and bootm_size is
+ used otherwise.
+
+ bootm_size - Memory range available for image processing in the bootm
+ command can be restricted. This variable is given as
+ a hexadecimal number and defines the size of the region
+ allowed for use by the bootm command. See also "bootm_low"
+ environment variable.
+
+ updatefile - Location of the software update file on a TFTP server, used
+ by the automatic software update feature. Please refer to
+ documentation in doc/README.update for more details.
+
+ autoload - if set to "no" (any string beginning with 'n'),
+ "bootp" will just load perform a lookup of the
+ configuration from the BOOTP server, but not try to
+ load any image using TFTP
+
+ autostart - if set to "yes", an image loaded using the "bootp",
+ "rarpboot", "tftpboot" or "diskboot" commands will
+ be automatically started (by internally calling
+ "bootm")
+
+ If set to "no", a standalone image passed to the
+ "bootm" command will be copied to the load address
+ (and eventually uncompressed), but NOT be started.
+ This can be used to load and uncompress arbitrary
+ data.
+
+ fdt_high - if set this restricts the maximum address that the
+ flattened device tree will be copied into upon boot.
+ For example, if you have a system with 1 GB memory
+ at physical address 0x10000000, while Linux kernel
+ only recognizes the first 704 MB as low memory, you
+ may need to set fdt_high as 0x3C000000 to have the
+ device tree blob be copied to the maximum address
+ of the 704 MB low memory, so that Linux kernel can
+ access it during the boot procedure.
+
+ If this is set to the special value 0xFFFFFFFF then
+ the fdt will not be copied at all on boot. For this
+ to work it must reside in writable memory, have
+ sufficient padding on the end of it for u-boot to
+ add the information it needs into it, and the memory
+ must be accessible by the kernel.
+
+ fdtcontroladdr- if set this is the address of the control flattened
+ device tree used by U-Boot when CONFIG_OF_CONTROL is
+ defined.
+
+ i2cfast - (PPC405GP|PPC405EP only)
+ if set to 'y' configures Linux I2C driver for fast
+ mode (400kHZ). This environment variable is used in
+ initialization code. So, for changes to be effective
+ it must be saved and board must be reset.
+
+ initrd_high - restrict positioning of initrd images:
+ If this variable is not set, initrd images will be
+ copied to the highest possible address in RAM; this
+ is usually what you want since it allows for
+ maximum initrd size. If for some reason you want to
+ make sure that the initrd image is loaded below the
+ CONFIG_SYS_BOOTMAPSZ limit, you can set this environment
+ variable to a value of "no" or "off" or "0".
+ Alternatively, you can set it to a maximum upper
+ address to use (U-Boot will still check that it
+ does not overwrite the U-Boot stack and data).
+
+ For instance, when you have a system with 16 MB
+ RAM, and want to reserve 4 MB from use by Linux,
+ you can do this by adding "mem=12M" to the value of
+ the "bootargs" variable. However, now you must make
+ sure that the initrd image is placed in the first
+ 12 MB as well - this can be done with
+
+ setenv initrd_high 00c00000
+
+ If you set initrd_high to 0xFFFFFFFF, this is an
+ indication to U-Boot that all addresses are legal
+ for the Linux kernel, including addresses in flash
+ memory. In this case U-Boot will NOT COPY the
+ ramdisk at all. This may be useful to reduce the
+ boot time on your system, but requires that this
+ feature is supported by your Linux kernel.
+
+ ipaddr - IP address; needed for tftpboot command
+
+ loadaddr - Default load address for commands like "bootp",
+ "rarpboot", "tftpboot", "loadb" or "diskboot"
+
+ loads_echo - see CONFIG_LOADS_ECHO
+
+ serverip - TFTP server IP address; needed for tftpboot command
+
+ bootretry - see CONFIG_BOOT_RETRY_TIME
+
+ bootdelaykey - see CONFIG_AUTOBOOT_DELAY_STR
+
+ bootstopkey - see CONFIG_AUTOBOOT_STOP_STR
+
+ ethprime - controls which interface is used first.
+
+ ethact - controls which interface is currently active.
+ For example you can do the following
+
+ => setenv ethact FEC
+ => ping 192.168.0.1 # traffic sent on FEC
+ => setenv ethact SCC
+ => ping 10.0.0.1 # traffic sent on SCC
+
+ ethrotate - When set to "no" U-Boot does not go through all
+ available network interfaces.
+ It just stays at the currently selected interface.
+
+ netretry - When set to "no" each network operation will
+ either succeed or fail without retrying.
+ When set to "once" the network operation will
+ fail when all the available network interfaces
+ are tried once without success.
+ Useful on scripts which control the retry operation
+ themselves.
+
+ npe_ucode - set load address for the NPE microcode
+
+ silent_linux - If set then Linux will be told to boot silently, by
+ changing the console to be empty. If "yes" it will be
+ made silent. If "no" it will not be made silent. If
+ unset, then it will be made silent if the U-Boot console
+ is silent.
+
+ tftpsrcp - If this is set, the value is used for TFTP's
+ UDP source port.
+
+ tftpdstp - If this is set, the value is used for TFTP's UDP
+ destination port instead of the Well Know Port 69.
+
+ tftpblocksize - Block size to use for TFTP transfers; if not set,
+ we use the TFTP server's default block size
+
+ tftptimeout - Retransmission timeout for TFTP packets (in milli-
+ seconds, minimum value is 1000 = 1 second). Defines
+ when a packet is considered to be lost so it has to
+ be retransmitted. The default is 5000 = 5 seconds.
+ Lowering this value may make downloads succeed
+ faster in networks with high packet loss rates or
+ with unreliable TFTP servers.
+
+ tftptimeoutcountmax - maximum count of TFTP timeouts (no
+ unit, minimum value = 0). Defines how many timeouts
+ can happen during a single file transfer before that
+ transfer is aborted. The default is 10, and 0 means
+ 'no timeouts allowed'. Increasing this value may help
+ downloads succeed with high packet loss rates, or with
+ unreliable TFTP servers or client hardware.
+
+ vlan - When set to a value < 4095 the traffic over
+ Ethernet is encapsulated/received over 802.1q
+ VLAN tagged frames.
+
+ bootpretryperiod - Period during which BOOTP/DHCP sends retries.
+ Unsigned value, in milliseconds. If not set, the period will
+ be either the default (28000), or a value based on
+ CONFIG_NET_RETRY_COUNT, if defined. This value has
+ precedence over the valu based on CONFIG_NET_RETRY_COUNT.
+
+The following image location variables contain the location of images
+used in booting. The "Image" column gives the role of the image and is
+not an environment variable name. The other columns are environment
+variable names. "File Name" gives the name of the file on a TFTP
+server, "RAM Address" gives the location in RAM the image will be
+loaded to, and "Flash Location" gives the image's address in NOR
+flash or offset in NAND flash.
+
+*Note* - these variables don't have to be defined for all boards, some
+boards currently use other variables for these purposes, and some
+boards use these variables for other purposes.
+
+Image File Name RAM Address Flash Location
+----- --------- ----------- --------------
+u-boot u-boot u-boot_addr_r u-boot_addr
+Linux kernel bootfile kernel_addr_r kernel_addr
+device tree blob fdtfile fdt_addr_r fdt_addr
+ramdisk ramdiskfile ramdisk_addr_r ramdisk_addr
+
+The following environment variables may be used and automatically
+updated by the network boot commands ("bootp" and "rarpboot"),
+depending the information provided by your boot server:
+
+ bootfile - see above
+ dnsip - IP address of your Domain Name Server
+ dnsip2 - IP address of your secondary Domain Name Server
+ gatewayip - IP address of the Gateway (Router) to use
+ hostname - Target hostname
+ ipaddr - see above
+ netmask - Subnet Mask
+ rootpath - Pathname of the root filesystem on the NFS server
+ serverip - see above
+
+
+There are two special Environment Variables:
+
+ serial# - contains hardware identification information such
+ as type string and/or serial number
+ ethaddr - Ethernet address
+
+These variables can be set only once (usually during manufacturing of
+the board). U-Boot refuses to delete or overwrite these variables
+once they have been set once.
+
+
+Further special Environment Variables:
+
+ ver - Contains the U-Boot version string as printed
+ with the "version" command. This variable is
+ readonly (see CONFIG_VERSION_VARIABLE).
+
+
+Please note that changes to some configuration parameters may take
+only effect after the next boot (yes, that's just like Windoze :-).
+
+
+Callback functions for environment variables:
+---------------------------------------------
+
+For some environment variables, the behavior of u-boot needs to change
+when their values are changed. This functionality allows functions to
+be associated with arbitrary variables. On creation, overwrite, or
+deletion, the callback will provide the opportunity for some side
+effect to happen or for the change to be rejected.
+
+The callbacks are named and associated with a function using the
+U_BOOT_ENV_CALLBACK macro in your board or driver code.
+
+These callbacks are associated with variables in one of two ways. The
+static list can be added to by defining CONFIG_ENV_CALLBACK_LIST_STATIC
+in the board configuration to a string that defines a list of
+associations. The list must be in the following format:
+
+ entry = variable_name[:callback_name]
+ list = entry[,list]
+
+If the callback name is not specified, then the callback is deleted.
+Spaces are also allowed anywhere in the list.
+
+Callbacks can also be associated by defining the ".callbacks" variable
+with the same list format above. Any association in ".callbacks" will
+override any association in the static list. You can define
+CONFIG_ENV_CALLBACK_LIST_DEFAULT to a list (string) to define the
+".callbacks" environment variable in the default or embedded environment.
+
+If CONFIG_REGEX is defined, the variable_name above is evaluated as a
+regular expression. This allows multiple variables to be connected to
+the same callback without explicitly listing them all out.
+
+The signature of the callback functions is:
+
+ int callback(const char *name, const char *value, enum env_op op, int flags)
+
+* name - changed environment variable
+* value - new value of the environment variable
+* op - operation (create, overwrite, or delete)
+* flags - attributes of the environment variable change, see flags H_* in
+ include/search.h
+
+The return value is 0 if the variable change is accepted and 1 otherwise.
+
+Command Line Parsing:
+=====================
+
+There are two different command line parsers available with U-Boot:
+the old "simple" one, and the much more powerful "hush" shell:
+
+Old, simple command line parser:
+--------------------------------
+
+- supports environment variables (through setenv / saveenv commands)
+- several commands on one line, separated by ';'
+- variable substitution using "... ${name} ..." syntax
+- special characters ('$', ';') can be escaped by prefixing with '\',
+ for example:
+ setenv bootcmd bootm \${address}
+- You can also escape text by enclosing in single apostrophes, for example:
+ setenv addip 'setenv bootargs $bootargs ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname::off'
+
+Hush shell:
+-----------
+
+- similar to Bourne shell, with control structures like
+ if...then...else...fi, for...do...done; while...do...done,
+ until...do...done, ...
+- supports environment ("global") variables (through setenv / saveenv
+ commands) and local shell variables (through standard shell syntax
+ "name=value"); only environment variables can be used with "run"
+ command
+
+General rules:
+--------------
+
+(1) If a command line (or an environment variable executed by a "run"
+ command) contains several commands separated by semicolon, and
+ one of these commands fails, then the remaining commands will be
+ executed anyway.
+
+(2) If you execute several variables with one call to run (i. e.
+ calling run with a list of variables as arguments), any failing
+ command will cause "run" to terminate, i. e. the remaining
+ variables are not executed.
+
+Note for Redundant Ethernet Interfaces:
+=======================================
+
+Some boards come with redundant Ethernet interfaces; U-Boot supports
+such configurations and is capable of automatic selection of a
+"working" interface when needed. MAC assignment works as follows:
+
+Network interfaces are numbered eth0, eth1, eth2, ... Corresponding
+MAC addresses can be stored in the environment as "ethaddr" (=>eth0),
+"eth1addr" (=>eth1), "eth2addr", ...
+
+If the network interface stores some valid MAC address (for instance
+in SROM), this is used as default address if there is NO correspon-
+ding setting in the environment; if the corresponding environment
+variable is set, this overrides the settings in the card; that means:
+
+o If the SROM has a valid MAC address, and there is no address in the
+ environment, the SROM's address is used.
+
+o If there is no valid address in the SROM, and a definition in the
+ environment exists, then the value from the environment variable is
+ used.
+
+o If both the SROM and the environment contain a MAC address, and
+ both addresses are the same, this MAC address is used.
+
+o If both the SROM and the environment contain a MAC address, and the
+ addresses differ, the value from the environment is used and a
+ warning is printed.
+
+o If neither SROM nor the environment contain a MAC address, an error
+ is raised. If CONFIG_NET_RANDOM_ETHADDR is defined, then in this case
+ a random, locally-assigned MAC is used.
+
+If Ethernet drivers implement the 'write_hwaddr' function, valid MAC addresses
+will be programmed into hardware as part of the initialization process. This
+may be skipped by setting the appropriate 'ethmacskip' environment variable.
+The naming convention is as follows:
+"ethmacskip" (=>eth0), "eth1macskip" (=>eth1) etc.
+
+Image Formats:
+==============
+
+U-Boot is capable of booting (and performing other auxiliary operations on)
+images in two formats:
+
+New uImage format (FIT)
+-----------------------
+
+Flexible and powerful format based on Flattened Image Tree -- FIT (similar
+to Flattened Device Tree). It allows the use of images with multiple
+components (several kernels, ramdisks, etc.), with contents protected by
+SHA1, MD5 or CRC32. More details are found in the doc/uImage.FIT directory.
+
+
+Old uImage format
+-----------------
+
+Old image format is based on binary files which can be basically anything,
+preceded by a special header; see the definitions in include/image.h for
+details; basically, the header defines the following image properties:
+
+* Target Operating System (Provisions for OpenBSD, NetBSD, FreeBSD,
+ 4.4BSD, Linux, SVR4, Esix, Solaris, Irix, SCO, Dell, NCR, VxWorks,
+ LynxOS, pSOS, QNX, RTEMS, INTEGRITY;
+ Currently supported: Linux, NetBSD, VxWorks, QNX, RTEMS, LynxOS,
+ INTEGRITY).
+* Target CPU Architecture (Provisions for Alpha, ARM, Intel x86,
+ IA64, MIPS, NDS32, Nios II, PowerPC, IBM S390, SuperH, Sparc, Sparc 64 Bit;
+ Currently supported: ARM, Intel x86, MIPS, NDS32, Nios II, PowerPC).
+* Compression Type (uncompressed, gzip, bzip2)
+* Load Address
+* Entry Point
+* Image Name
+* Image Timestamp
+
+The header is marked by a special Magic Number, and both the header
+and the data portions of the image are secured against corruption by
+CRC32 checksums.
+
+
+Linux Support:
+==============
+
+Although U-Boot should support any OS or standalone application
+easily, the main focus has always been on Linux during the design of
+U-Boot.
+
+U-Boot includes many features that so far have been part of some
+special "boot loader" code within the Linux kernel. Also, any
+"initrd" images to be used are no longer part of one big Linux image;
+instead, kernel and "initrd" are separate images. This implementation
+serves several purposes:
+
+- the same features can be used for other OS or standalone
+ applications (for instance: using compressed images to reduce the
+ Flash memory footprint)
+
+- it becomes much easier to port new Linux kernel versions because
+ lots of low-level, hardware dependent stuff are done by U-Boot
+
+- the same Linux kernel image can now be used with different "initrd"
+ images; of course this also means that different kernel images can
+ be run with the same "initrd". This makes testing easier (you don't
+ have to build a new "zImage.initrd" Linux image when you just
+ change a file in your "initrd"). Also, a field-upgrade of the
+ software is easier now.
+
+
+Linux HOWTO:
+============
+
+Porting Linux to U-Boot based systems:
+---------------------------------------
+
+U-Boot cannot save you from doing all the necessary modifications to
+configure the Linux device drivers for use with your target hardware
+(no, we don't intend to provide a full virtual machine interface to
+Linux :-).
+
+But now you can ignore ALL boot loader code (in arch/powerpc/mbxboot).
+
+Just make sure your machine specific header file (for instance
+include/asm-ppc/tqm8xx.h) includes the same definition of the Board
+Information structure as we define in include/asm-<arch>/u-boot.h,
+and make sure that your definition of IMAP_ADDR uses the same value
+as your U-Boot configuration in CONFIG_SYS_IMMR.
+
+Note that U-Boot now has a driver model, a unified model for drivers.
+If you are adding a new driver, plumb it into driver model. If there
+is no uclass available, you are encouraged to create one. See
+doc/driver-model.
+
+
+Configuring the Linux kernel:
+-----------------------------
+
+No specific requirements for U-Boot. Make sure you have some root
+device (initial ramdisk, NFS) for your target system.
+
+
+Building a Linux Image:
+-----------------------
+
+With U-Boot, "normal" build targets like "zImage" or "bzImage" are
+not used. If you use recent kernel source, a new build target
+"uImage" will exist which automatically builds an image usable by
+U-Boot. Most older kernels also have support for a "pImage" target,
+which was introduced for our predecessor project PPCBoot and uses a
+100% compatible format.
+
+Example:
+
+ make TQM850L_defconfig
+ make oldconfig
+ make dep
+ make uImage
+
+The "uImage" build target uses a special tool (in 'tools/mkimage') to
+encapsulate a compressed Linux kernel image with header information,
+CRC32 checksum etc. for use with U-Boot. This is what we are doing:
+
+* build a standard "vmlinux" kernel image (in ELF binary format):
+
+* convert the kernel into a raw binary image:
+
+ ${CROSS_COMPILE}-objcopy -O binary \
+ -R .note -R .comment \
+ -S vmlinux linux.bin
+
+* compress the binary image:
+
+ gzip -9 linux.bin
+
+* package compressed binary image for U-Boot:
+
+ mkimage -A ppc -O linux -T kernel -C gzip \
+ -a 0 -e 0 -n "Linux Kernel Image" \
+ -d linux.bin.gz uImage
+
+
+The "mkimage" tool can also be used to create ramdisk images for use
+with U-Boot, either separated from the Linux kernel image, or
+combined into one file. "mkimage" encapsulates the images with a 64
+byte header containing information about target architecture,
+operating system, image type, compression method, entry points, time
+stamp, CRC32 checksums, etc.
+
+"mkimage" can be called in two ways: to verify existing images and
+print the header information, or to build new images.
+
+In the first form (with "-l" option) mkimage lists the information
+contained in the header of an existing U-Boot image; this includes
+checksum verification:
+
+ tools/mkimage -l image
+ -l ==> list image header information
+
+The second form (with "-d" option) is used to build a U-Boot image
+from a "data file" which is used as image payload:
+
+ tools/mkimage -A arch -O os -T type -C comp -a addr -e ep \
+ -n name -d data_file image
+ -A ==> set architecture to 'arch'
+ -O ==> set operating system to 'os'
+ -T ==> set image type to 'type'
+ -C ==> set compression type 'comp'
+ -a ==> set load address to 'addr' (hex)
+ -e ==> set entry point to 'ep' (hex)
+ -n ==> set image name to 'name'
+ -d ==> use image data from 'datafile'
+
+Right now, all Linux kernels for PowerPC systems use the same load
+address (0x00000000), but the entry point address depends on the
+kernel version:
+
+- 2.2.x kernels have the entry point at 0x0000000C,
+- 2.3.x and later kernels have the entry point at 0x00000000.
+
+So a typical call to build a U-Boot image would read:
+
+ -> tools/mkimage -n '2.4.4 kernel for TQM850L' \
+ > -A ppc -O linux -T kernel -C gzip -a 0 -e 0 \
+ > -d /opt/elsk/ppc_8xx/usr/src/linux-2.4.4/arch/powerpc/coffboot/vmlinux.gz \
+ > examples/uImage.TQM850L
+ Image Name: 2.4.4 kernel for TQM850L
+ Created: Wed Jul 19 02:34:59 2000
+ Image Type: PowerPC Linux Kernel Image (gzip compressed)
+ Data Size: 335725 Bytes = 327.86 kB = 0.32 MB
+ Load Address: 0x00000000
+ Entry Point: 0x00000000
+
+To verify the contents of the image (or check for corruption):
+
+ -> tools/mkimage -l examples/uImage.TQM850L
+ Image Name: 2.4.4 kernel for TQM850L
+ Created: Wed Jul 19 02:34:59 2000
+ Image Type: PowerPC Linux Kernel Image (gzip compressed)
+ Data Size: 335725 Bytes = 327.86 kB = 0.32 MB
+ Load Address: 0x00000000
+ Entry Point: 0x00000000
+
+NOTE: for embedded systems where boot time is critical you can trade
+speed for memory and install an UNCOMPRESSED image instead: this
+needs more space in Flash, but boots much faster since it does not
+need to be uncompressed:
+
+ -> gunzip /opt/elsk/ppc_8xx/usr/src/linux-2.4.4/arch/powerpc/coffboot/vmlinux.gz
+ -> tools/mkimage -n '2.4.4 kernel for TQM850L' \
+ > -A ppc -O linux -T kernel -C none -a 0 -e 0 \
+ > -d /opt/elsk/ppc_8xx/usr/src/linux-2.4.4/arch/powerpc/coffboot/vmlinux \
+ > examples/uImage.TQM850L-uncompressed
+ Image Name: 2.4.4 kernel for TQM850L
+ Created: Wed Jul 19 02:34:59 2000
+ Image Type: PowerPC Linux Kernel Image (uncompressed)
+ Data Size: 792160 Bytes = 773.59 kB = 0.76 MB
+ Load Address: 0x00000000
+ Entry Point: 0x00000000
+
+
+Similar you can build U-Boot images from a 'ramdisk.image.gz' file
+when your kernel is intended to use an initial ramdisk:
+
+ -> tools/mkimage -n 'Simple Ramdisk Image' \
+ > -A ppc -O linux -T ramdisk -C gzip \
+ > -d /LinuxPPC/images/SIMPLE-ramdisk.image.gz examples/simple-initrd
+ Image Name: Simple Ramdisk Image
+ Created: Wed Jan 12 14:01:50 2000
+ Image Type: PowerPC Linux RAMDisk Image (gzip compressed)
+ Data Size: 566530 Bytes = 553.25 kB = 0.54 MB
+ Load Address: 0x00000000
+ Entry Point: 0x00000000
+
+The "dumpimage" is a tool to disassemble images built by mkimage. Its "-i"
+option performs the converse operation of the mkimage's second form (the "-d"
+option). Given an image built by mkimage, the dumpimage extracts a "data file"
+from the image:
+
+ tools/dumpimage -i image -T type -p position data_file
+ -i ==> extract from the 'image' a specific 'data_file'
+ -T ==> set image type to 'type'
+ -p ==> 'position' (starting at 0) of the 'data_file' inside the 'image'
+
+
+Installing a Linux Image:
+-------------------------
+
+To downloading a U-Boot image over the serial (console) interface,
+you must convert the image to S-Record format:
+
+ objcopy -I binary -O srec examples/image examples/image.srec
+
+The 'objcopy' does not understand the information in the U-Boot
+image header, so the resulting S-Record file will be relative to
+address 0x00000000. To load it to a given address, you need to
+specify the target address as 'offset' parameter with the 'loads'
+command.
+
+Example: install the image to address 0x40100000 (which on the
+TQM8xxL is in the first Flash bank):
+
+ => erase 40100000 401FFFFF
+
+ .......... done
+ Erased 8 sectors
+
+ => loads 40100000
+ ## Ready for S-Record download ...

+ 15989 15990 15991 15992
+ [file transfer complete]
+ [connected]
+ ## Start Addr = 0x00000000
+
+
+You can check the success of the download using the 'iminfo' command;
+this includes a checksum verification so you can be sure no data
+corruption happened:
+
+ => imi 40100000

+ ## Checking Image at 40100000 ...

+Boot Linux:
+-----------
+
+The "bootm" command is used to boot an application that is stored in
+memory (RAM or Flash). In case of a Linux kernel image, the contents
+of the "bootargs" environment variable is passed to the kernel as
+parameters. You can check and modify this variable using the
+"printenv" and "setenv" commands:
+
+
+ => printenv bootargs
+ bootargs=root=/dev/ram
+
+ => setenv bootargs root=/dev/nfs rw nfsroot=10.0.0.2:/LinuxPPC nfsaddrs=10.0.0.99:10.0.0.2

+
+More About U-Boot Image Types:
+------------------------------
+
+U-Boot supports the following image types:
+
+ "Standalone Programs" are directly runnable in the environment
+ provided by U-Boot; it is expected that (if they behave
+ well) you can continue to work in U-Boot after return from
+ the Standalone Program.
+ "OS Kernel Images" are usually images of some Embedded OS which
+ will take over control completely. Usually these programs
+ will install their own set of exception handlers, device
+ drivers, set up the MMU, etc. - this means, that you cannot
+ expect to re-enter U-Boot except by resetting the CPU.
+ "RAMDisk Images" are more or less just data blocks, and their
+ parameters (address, size) are passed to an OS kernel that is
+ being started.
+ "Multi-File Images" contain several images, typically an OS
+ (Linux) kernel image and one or more data images like
+ RAMDisks. This construct is useful for instance when you want
+ to boot over the network using BOOTP etc., where the boot
+ server provides just a single image file, but you want to get
+ for instance an OS kernel and a RAMDisk image.
+
+ "Multi-File Images" start with a list of image sizes, each
+ image size (in bytes) specified by an "uint32_t" in network
+ byte order. This list is terminated by an "(uint32_t)0".
+ Immediately after the terminating 0 follow the images, one by
+ one, all aligned on "uint32_t" boundaries (size rounded up to
+ a multiple of 4 bytes).
+
+ "Firmware Images" are binary images containing firmware (like
+ U-Boot or FPGA images) which usually will be programmed to
+ flash memory.
+
+ "Script files" are command sequences that will be executed by
+ U-Boot's command interpreter; this feature is especially
+ useful when you configure U-Boot to use a real shell (hush)
+ as command interpreter.
+
+Booting the Linux zImage:
+-------------------------
+
+On some platforms, it's possible to boot Linux zImage. This is done
+using the "bootz" command. The syntax of "bootz" command is the same
+as the syntax of "bootm" command.
+
+Note, defining the CONFIG_SUPPORT_RAW_INITRD allows user to supply
+kernel with raw initrd images. The syntax is slightly different, the
+address of the initrd must be augmented by it's size, in the following
+format: "<initrd addres>:<initrd size>".
+
+
+Standalone HOWTO:
+=================
+
+One of the features of U-Boot is that you can dynamically load and
+run "standalone" applications, which can use some resources of
+U-Boot like console I/O functions or interrupt services.
+
+Two simple examples are included with the sources:
+
+"Hello World" Demo:
+-------------------
+
+'examples/hello_world.c' contains a small "Hello World" Demo
+application; it is automatically compiled when you build U-Boot.
+It's configured to run at address 0x00040004, so you can play with it
+like that:
+
+ => loads
+ ## Ready for S-Record download ...
+ ~>examples/hello_world.srec
+ 1 2 3 4 5 6 7 8 9 10 11 ...
+ [file transfer complete]
+ [connected]
+ ## Start Addr = 0x00040004
+
+ => go 40004 Hello World! This is a test.
+ ## Starting application at 0x00040004 ...
+ Hello World
+ argc = 7
+ argv[0] = "40004"
+ argv[1] = "Hello"
+ argv[2] = "World!"
+ argv[3] = "This"
+ argv[4] = "is"
+ argv[5] = "a"
+ argv[6] = "test."
+ argv[7] = "<NULL>"
+ Hit any key to exit ...
+
+ ## Application terminated, rc = 0x0
+
+Another example, which demonstrates how to register a CPM interrupt
+handler with the U-Boot code, can be found in 'examples/timer.c'.
+Here, a CPM timer is set up to generate an interrupt every second.
+The interrupt service routine is trivial, just printing a '.'
+character, but this is just a demo program. The application can be
+controlled by the following keys:
+
+ ? - print current values og the CPM Timer registers
+ b - enable interrupts and start timer
+ e - stop timer and disable interrupts
+ q - quit application
+
+ => loads

+Minicom warning:
+================
+
+Over time, many people have reported problems when trying to use the
+"minicom" terminal emulation program for serial download. I (wd)
+consider minicom to be broken, and recommend not to use it. Under
+Unix, I recommend to use C-Kermit for general purpose use (and
+especially for kermit binary protocol download ("loadb" command), and
+use "cu" for S-Record download ("loads" command). See
+http://www.denx.de/wiki/view/DULG/SystemSetup#Section_4.3.
+for help with kermit.
+
+
+Nevertheless, if you absolutely want to use it try adding this
+configuration to your "File transfer protocols" section:
+
+ Name Program Name U/D FullScr IO-Red. Multi
+ X kermit /usr/bin/kermit -i -l %l -s Y U Y N N
+ Y kermit /usr/bin/kermit -i -l %l -r N D Y N N

+NetBSD Notes:
+=============
+
+Starting at version 0.9.2, U-Boot supports NetBSD both as host
+(build U-Boot) and target system (boots NetBSD/mpc8xx).
+
+Building requires a cross environment; it is known to work on
+NetBSD/i386 with the cross-powerpc-netbsd-1.3 package (you will also
+need gmake since the Makefiles are not compatible with BSD make).
+Note that the cross-powerpc package does not install include files;
+attempting to build U-Boot will fail because <machine/ansi.h> is
+missing. This file has to be installed and patched manually:
+
+ # cd /usr/pkg/cross/powerpc-netbsd/include
+ # mkdir powerpc
+ # ln -s powerpc machine
+ # cp /usr/src/sys/arch/powerpc/include/ansi.h powerpc/ansi.h
+ # ${EDIT} powerpc/ansi.h ## must remove __va_list, _BSD_VA_LIST
+
+Native builds *don't* work due to incompatibilities between native
+and U-Boot include files.
+
+Booting assumes that (the first part of) the image booted is a
+stage-2 loader which in turn loads and then invokes the kernel
+proper. Loader sources will eventually appear in the NetBSD source
+tree (probably in sys/arc/mpc8xx/stand/u-boot_stage2/); in the
+meantime, see ftp://ftp.denx.de/pub/u-boot/ppcboot_stage2.tar.gz
+
+
+Implementation Internals:
+=========================
+
+The following is not intended to be a complete description of every
+implementation detail. However, it should help to understand the
+inner workings of U-Boot and make it easier to port it to custom
+hardware.
+
+
+Initial Stack, Global Data:
+---------------------------
+
+The implementation of U-Boot is complicated by the fact that U-Boot
+starts running out of ROM (flash memory), usually without access to
+system RAM (because the memory controller is not initialized yet).
+This means that we don't have writable Data or BSS segments, and BSS
+is not initialized as zero. To be able to get a C environment working
+at all, we have to allocate at least a minimal stack. Implementation
+options for this are defined and restricted by the CPU used: Some CPU
+models provide on-chip memory (like the IMMR area on MPC8xx and
+MPC826x processors), on others (parts of) the data cache can be
+locked as (mis-) used as memory, etc.
+
+ Chris Hallinan posted a good summary of these issues to the
+ U-Boot mailing list:
+
+ Subject: RE: [U-Boot-Users] RE: More On Memory Bank x (nothingness)?
+ From: "Chris Hallinan" <clh@net1plus.com>
+ Date: Mon, 10 Feb 2003 16:43:46 -0500 (22:43 MET)
+ ...
+
+ Correct me if I'm wrong, folks, but the way I understand it
+ is this: Using DCACHE as initial RAM for Stack, etc, does not
+ require any physical RAM backing up the cache. The cleverness
+ is that the cache is being used as a temporary supply of
+ necessary storage before the SDRAM controller is setup. It's
+ beyond the scope of this list to explain the details, but you
+ can see how this works by studying the cache architecture and
+ operation in the architecture and processor-specific manuals.
+
+ OCM is On Chip Memory, which I believe the 405GP has 4K. It
+ is another option for the system designer to use as an
+ initial stack/RAM area prior to SDRAM being available. Either
+ option should work for you. Using CS 4 should be fine if your
+ board designers haven't used it for something that would
+ cause you grief during the initial boot! It is frequently not
+ used.
+
+ CONFIG_SYS_INIT_RAM_ADDR should be somewhere that won't interfere
+ with your processor/board/system design. The default value
+ you will find in any recent u-boot distribution in
+ walnut.h should work for you. I'd set it to a value larger
+ than your SDRAM module. If you have a 64MB SDRAM module, set
+ it above 400_0000. Just make sure your board has no resources
+ that are supposed to respond to that address! That code in
+ start.S has been around a while and should work as is when
+ you get the config right.
+
+ -Chris Hallinan

+
+It is essential to remember this, since it has some impact on the C
+code for the initialization procedures:
+
+* Initialized global data (data segment) is read-only. Do not attempt
+ to write it.
+
+* Do not use any uninitialized global data (or implicitly initialized
+ as zero data - BSS segment) at all - this is undefined, initiali-
+ zation is performed later (when relocating to RAM).
+
+* Stack space is very limited. Avoid big data buffers or things like
+ that.
+
+Having only the stack as writable memory limits means we cannot use
+normal global data to share information between the code. But it
+turned out that the implementation of U-Boot can be greatly
+simplified by making a global data structure (gd_t) available to all
+functions. We could pass a pointer to this data as argument to _all_
+functions, but this would bloat the code. Instead we use a feature of
+the GCC compiler (Global Register Variables) to share the data: we
+place a pointer (gd) to the global data into a register which we
+reserve for this purpose.
+
+When choosing a register for such a purpose we are restricted by the
+relevant (E)ABI specifications for the current architecture, and by
+GCC's implementation.
+
+For PowerPC, the following registers have specific use:
+ R1: stack pointer
+ R2: reserved for system use
+ R3-R4: parameter passing and return values
+ R5-R10: parameter passing
+ R13: small data area pointer
+ R30: GOT pointer
+ R31: frame pointer
+
+ (U-Boot also uses R12 as internal GOT pointer. r12
+ is a volatile register so r12 needs to be reset when
+ going back and forth between asm and C)
+
+ ==> U-Boot will use R2 to hold a pointer to the global data
+
+ Note: on PPC, we could use a static initializer (since the
+ address of the global data structure is known at compile time),
+ but it turned out that reserving a register results in somewhat
+ smaller code - although the code savings are not that big (on
+ average for all boards 752 bytes for the whole U-Boot image,
+ 624 text + 127 data).
+
+On ARM, the following registers are used:
+
+ R0: function argument word/integer result

+ R11: argument (frame) pointer
+ R12: temporary workspace
+ R13: stack pointer
+ R14: link register
+ R15: program counter
+
+ ==> U-Boot will use R9 to hold a pointer to the global data
+
+ Note: on ARM, only R_ARM_RELATIVE relocations are supported.
+
+On Nios II, the ABI is documented here:
+ http://www.altera.com/literature/hb/nios2/n2cpu_nii51016.pdf
+
+ ==> U-Boot will use gp to hold a pointer to the global data
+
+ Note: on Nios II, we give "-G0" option to gcc and don't use gp
+ to access small data sections, so gp is free.
+
+On NDS32, the following registers are used:
+

+ R2-R5: argument
+ R15: temporary register for assembler
+ R16: trampoline register
+ R28: frame pointer (FP)
+ R29: global pointer (GP)

+

+

+
+Memory Management:
+------------------
+
+U-Boot runs in system state and uses physical addresses, i.e. the
+MMU is not used either for address mapping nor for memory protection.
+
+The available memory is mapped to fixed addresses using the memory
+controller. In this process, a contiguous block is formed for each
+memory type (Flash, SDRAM, SRAM), even when it consists of several
+physical memory banks.
+
+U-Boot is installed in the first 128 kB of the first Flash bank (on
+TQM8xxL modules this is the range 0x40000000 ... 0x4001FFFF). After
+booting and sizing and initializing DRAM, the code relocates itself
+to the upper end of DRAM. Immediately below the U-Boot code some
+memory is reserved for use by malloc() [see CONFIG_SYS_MALLOC_LEN
+configuration setting]. Below that, a structure with global Board
+Info data is placed, followed by the stack (growing downward).
+
+Additionally, some exception handler code is copied to the low 8 kB
+of DRAM (0x00000000 ... 0x00001FFF).
+
+So a typical memory configuration with 16 MB of DRAM could look like
+this:
+
+ 0x0000 0000 Exception Vector code
+ :
+ 0x0000 1FFF
+ 0x0000 2000 Free for Application Use
+ :
+ :
+
+ :
+ :
+ 0x00FB FF20 Monitor Stack (Growing downward)
+ 0x00FB FFAC Board Info Data and permanent copy of global data
+ 0x00FC 0000 Malloc Arena
+ :
+ 0x00FD FFFF
+ 0x00FE 0000 RAM Copy of Monitor Code
+ ... eventually: LCD or video framebuffer
+ ... eventually: pRAM (Protected RAM - unchanged by reset)
+ 0x00FF FFFF [End of RAM]
+
+
+System Initialization:
+----------------------
+
+In the reset configuration, U-Boot starts at the reset entry point
+(on most PowerPC systems at address 0x00000100). Because of the reset
+configuration for CS0# this is a mirror of the on board Flash memory.
+To be able to re-map memory U-Boot then jumps to its link address.
+To be able to implement the initialization code in C, a (small!)
+initial stack is set up in the internal Dual Ported RAM (in case CPUs
+which provide such a feature like), or in a locked part of the data
+cache. After that, U-Boot initializes the CPU core, the caches and
+the SIU.
+
+Next, all (potentially) available memory banks are mapped using a
+preliminary mapping. For example, we put them on 512 MB boundaries
+(multiples of 0x20000000: SDRAM on 0x00000000 and 0x20000000, Flash
+on 0x40000000 and 0x60000000, SRAM on 0x80000000). Then UPM A is
+programmed for SDRAM access. Using the temporary configuration, a
+simple memory test is run that determines the size of the SDRAM
+banks.
+
+When there is more than one SDRAM bank, and the banks are of
+different size, the largest is mapped first. For equal size, the first
+bank (CS2#) is mapped first. The first mapping is always for address
+0x00000000, with any additional banks following immediately to create
+contiguous memory starting from 0.
+
+Then, the monitor installs itself at the upper end of the SDRAM area
+and allocates memory for use by malloc() and for the global Board
+Info data; also, the exception vector code is copied to the low RAM
+pages, and the final stack is set up.
+
+Only after this relocation will you have a "normal" C environment;
+until that you are restricted in several ways, mostly because you are
+running from ROM, and because the code will have to be relocated to a
+new address in RAM.

+
+Coding Standards:
+-----------------
+
+All contributions to U-Boot should conform to the Linux kernel
+coding style; see the kernel coding style guide at
+https://www.kernel.org/doc/html/latest/process/coding-style.html, and the
+script "scripts/Lindent" in your Linux kernel source directory.
+
+Source files originating from a different project (for example the
+MTD subsystem) are generally exempt from these guidelines and are not
+reformatted to ease subsequent migration to newer versions of those
+sources.
+
+Please note that U-Boot is implemented in C (and to some small parts in
+Assembler); no C++ is used, so please do not use C++ style comments (//)
+in your code.
+
+Please also stick to the following formatting rules:
+- remove any trailing white space
+- use TAB characters for indentation and vertical alignment, not spaces
+- make sure NOT to use DOS '\r\n' line feeds
+- do not add more than 2 consecutive empty lines to source files
+- do not add trailing empty lines to source files
+
+Submissions which do not conform to the standards may be returned
+with a request to reformat the changes.
+
+
+Submitting Patches:
+-------------------
+
+Since the number of patches for U-Boot is growing, we need to
+establish some rules. Submissions which do not conform to these rules
+may be rejected, even when they contain important and valuable stuff.
+
+Please see http://www.denx.de/wiki/U-Boot/Patches for details.
+
+Patches shall be sent to the u-boot mailing list <u-boot@lists.denx.de>;
+see https://lists.denx.de/listinfo/u-boot
+
+When you send a patch, please include the following information with
+it:
+
+* For bug fixes: a description of the bug and how your patch fixes
+ this bug. Please try to include a way of demonstrating that the
+ patch actually fixes something.
+
+* For new features: a description of the feature and your
+ implementation.
+
+* A CHANGELOG entry as plaintext (separate from the patch)
+
+* For major contributions, add a MAINTAINERS file with your
+ information and associated file and directory references.
+
+* When you add support for a new board, don't forget to add a
+ maintainer e-mail address to the boards.cfg file, too.
+
+* If your patch adds new configuration options, don't forget to
+ document these in the README file.
+
+* The patch itself. If you are using git (which is *strongly*
+ recommended) you can easily generate the patch using the
+ "git format-patch". If you then use "git send-email" to send it to
+ the U-Boot mailing list, you will avoid most of the common problems
+ with some other mail clients.
+
+ If you cannot use git, use "diff -purN OLD NEW". If your version of
+ diff does not support these options, then get the latest version of
+ GNU diff.
+
+ The current directory when running this command shall be the parent
+ directory of the U-Boot source tree (i. e. please make sure that
+ your patch includes sufficient directory information for the
+ affected files).
+
+ We prefer patches as plain text. MIME attachments are discouraged,
+ and compressed attachments must not be used.
+
+* If one logical set of modifications affects or creates several
+ files, all these changes shall be submitted in a SINGLE patch file.
+
+* Changesets that contain different, unrelated modifications shall be
+ submitted as SEPARATE patches, one patch per changeset.
+
+
+Notes:
+
+* Before sending the patch, run the buildman script on your patched
+ source tree and make sure that no errors or warnings are reported
+ for any of the boards.
+
+* Keep your modifications to the necessary minimum: A patch
+ containing several unrelated changes or arbitrary reformats will be
+ returned with a request to re-formatting / split it.
+
+* If you modify existing code, make sure that your new code does not
+ add to the memory footprint of the code ;-) Small is beautiful!
+ When adding new features, these should compile conditionally only
+ (using #ifdef), and the resulting code with the new feature
+ disabled must not need more memory than the old code without your
+ modification.
+
+* Remember that there is a size limit of 100 kB per message on the
+ u-boot mailing list. Bigger patches will be moderated. If they are
+ reasonable and not too big, they will be acknowledged. But patches
+ bigger than the size limit should be avoided.

+U-Boot machine/arch independent API for external apps
+=====================================================
+
+1. Main assumptions
+
+ - there is a single entry point (syscall) to the API
+
+ - per current design the syscall is a C-callable function in the U-Boot
+ text, which might evolve into a real syscall using machine exception trap
+ once this initial version proves functional
+
+ - the consumer app is responsible for producing appropriate context (call
+ number and arguments)
+
+ - upon entry, the syscall dispatches the call to other (existing) U-Boot
+ functional areas like networking or storage operations
+
+ - consumer application will recognize the API is available by searching
+ a specified (assumed by convention) range of address space for the
+ signature
+
+ - the U-Boot integral part of the API is meant to be thin and non-intrusive,
+ leaving as much processing as possible on the consumer application side,
+ for example it doesn't keep states, but relies on hints from the app and
+ so on
+
+ - optional (CONFIG_API)
+
+
+2. Calls
+
+ - console related (getc, putc, tstc etc.)
+ - system (reset, platform info)
+ - time (delay, current)
+ - env vars (enumerate all, get, set)
+ - devices (enumerate all, open, close, read, write); currently two classes
+ of devices are recognized and supported: network and storage (ide, scsi,
+ usb etc.)
+
+
+3. Structure overview
+
+ - core API, integral part of U-Boot, mandatory
+ - implements the single entry point (mimics UNIX syscall)
+
+ - glue
+ - entry point at the consumer side, allows to make syscall, mandatory
+ part
+
+ - helper conveniency wrappers so that consumer app does not have to use
+ the syscall directly, but in a more friendly manner (a la libc calls),
+ optional part
+
+ - consumer application
+ - calls directly, or leverages the provided glue mid-layer

+ * [ NOTE 1 ]:
+ * Data cache (L1 D$ or SL$) entire invalidate operation or data cache disable
+ * operation may result in unexpected behavior and data loss even if we flush
+ * data cache right before invalidation. That may happens if we store any context
+ * on stack (like we store BLINK register on stack before function call).
+ * BLINK register is the register where return address is automatically saved
+ * when we do function call with instructions like 'bl'.
+ *
+ * There is the real example:
+ * We may hang in the next code as we store any BLINK register on stack in
+ * invalidate_dcache_all() function.
+ *
+ * void flush_dcache_all() {
+ * __dc_entire_op(OP_FLUSH);
+ * // Other code //
+ * }
+ *
+ * void invalidate_dcache_all() {
+ * __dc_entire_op(OP_INV);
+ * // Other code //
+ * }
+ *
+ * void foo(void) {
+ * flush_dcache_all();
+ * invalidate_dcache_all();
+ * }
+ *
+ * Now let's see what really happens during that code execution:
+ *
+ * foo()
+ * |->> call flush_dcache_all
+ * [return address is saved to BLINK register]
+ * [push BLINK] (save to stack) ![point 1]
+ * |->> call __dc_entire_op(OP_FLUSH)
+ * [return address is saved to BLINK register]
+ * [flush L1 D$]
+ * return [jump to BLINK]
+ * <<------
+ * [other flush_dcache_all code]
+ * [pop BLINK] (get from stack)
+ * return [jump to BLINK]
+ * <<------
+ * |->> call invalidate_dcache_all
+ * [return address is saved to BLINK register]
+ * [push BLINK] (save to stack) ![point 2]
+ * |->> call __dc_entire_op(OP_FLUSH)
+ * [return address is saved to BLINK register]
+ * [invalidate L1 D$] ![point 3]
+ * // Oops!!!
+ * // We lose return address from invalidate_dcache_all function:
+ * // we save it to stack and invalidate L1 D$ after that!
+ * return [jump to BLINK]
+ * <<------
+ * [other invalidate_dcache_all code]
+ * [pop BLINK] (get from stack)
+ * // we don't have this data in L1 dcache as we invalidated it in [point 3]
+ * // so we get it from next memory level (for example DDR memory)
+ * // but in the memory we have value which we save in [point 1], which
+ * // is return address from flush_dcache_all function (instead of
+ * // address from current invalidate_dcache_all function which we
+ * // saved in [point 2] !)
+ * return [jump to BLINK]
+ * <<------
+ * // As BLINK points to invalidate_dcache_all, we call it again and
+ * // loop forever.
+ *
+ * Fortunately we may fix that by using flush & invalidation of D$ with a single
+ * one instruction (instead of flush and invalidation instructions pair) and
+ * enabling force function inline with '__attribute__((always_inline))' gcc
+ * attribute to avoid any function call (and BLINK store) between cache flush
+ * and disable.
+ *
+ *
+ * [ NOTE 2 ]:
+ * As of today we only support the following cache configurations on ARC.
+ * Other configurations may exist in HW (for example, since version 3.0 HS
+ * supports SL$ (L2 system level cache) disable) but we don't support it in SW.
+ * Configuration 1:

+ * Each clock can have zero, one, or two dividers which change the

+ * variable. If there are two dividers, they are the "pre-divider"
+ * and the "regular" or "downstream" divider. If there is only one,
+ * there is no pre-divider.
+ *
+ * A fixed divider is any non-zero (positive) value, and it
+ * indicates how the input rate is affected by the divider.
+ *
+ * The value of a variable divider is maintained in a sub-field of a
+ * 32-bit divider register. The position of the field in the
+ * register is defined by its offset and width. The value recorded
+ * in this field is always 1 less than the value it represents.
+ *
+ * In addition, a variable divider can indicate that some subset
+ * of its bits represent a "fractional" part of the divider. Such
+ * bits comprise the low-order portion of the divider field, and can
+ * be viewed as representing the portion of the divider that lies to
+ * the right of the decimal point. Most variable dividers have zero
+ * fractional bits. Variable dividers with non-zero fraction width
+ * still record a value 1 less than the value they represent; the
+ * added 1 does *not* affect the low-order bit in this case, it
+ * affects the bits above the fractional part only. (Often in this
+ * code a divider field value is distinguished from the value it
+ * represents by referring to the latter as a "divisor".)
+ *
+ * In order to avoid dealing with fractions, divider arithmetic is
+ * performed using "scaled" values. A scaled value is one that's
+ * been left-shifted by the fractional width of a divider. Dividing
+ * a scaled value by a scaled divisor produces the desired quotient
+ * without loss of precision and without any other special handling
+ * for fractions.
+ *
+ * The recorded value of a variable divider can be modified. To
+ * modify either divider (or both), a clock must be enabled (i.e.,
+ * using its gate). In addition, a trigger register (described
+ * below) must be used to commit the change, and polled to verify

+ * Each clock can have zero, one, or two dividers which change the

+ * variable. If there are two dividers, they are the "pre-divider"
+ * and the "regular" or "downstream" divider. If there is only one,
+ * there is no pre-divider.
+ *
+ * A fixed divider is any non-zero (positive) value, and it
+ * indicates how the input rate is affected by the divider.
+ *
+ * The value of a variable divider is maintained in a sub-field of a
+ * 32-bit divider register. The position of the field in the
+ * register is defined by its offset and width. The value recorded
+ * in this field is always 1 less than the value it represents.
+ *
+ * In addition, a variable divider can indicate that some subset
+ * of its bits represent a "fractional" part of the divider. Such
+ * bits comprise the low-order portion of the divider field, and can
+ * be viewed as representing the portion of the divider that lies to
+ * the right of the decimal point. Most variable dividers have zero
+ * fractional bits. Variable dividers with non-zero fraction width
+ * still record a value 1 less than the value they represent; the
+ * added 1 does *not* affect the low-order bit in this case, it
+ * affects the bits above the fractional part only. (Often in this
+ * code a divider field value is distinguished from the value it
+ * represents by referring to the latter as a "divisor".)
+ *
+ * In order to avoid dealing with fractions, divider arithmetic is
+ * performed using "scaled" values. A scaled value is one that's
+ * been left-shifted by the fractional width of a divider. Dividing
+ * a scaled value by a scaled divisor produces the desired quotient
+ * without loss of precision and without any other special handling
+ * for fractions.
+ *
+ * The recorded value of a variable divider can be modified. To
+ * modify either divider (or both), a clock must be enabled (i.e.,
+ * using its gate). In addition, a trigger register (described
+ * below) must be used to commit the change, and polled to verify

+Core instruction prefetch disable
+---------------------------------
+To disable instruction prefetch of core; hwconfig needs to be updated.
+for e.g.
+setenv hwconfig 'fsl_ddr:bank_intlv=auto;core_prefetch:disable=0x02'
+
+Here 0x02 can be replaced with any valid value except Mask[0] bit. It
+represents 64 bit mask. The 64-bit Mask has one bit for each core.
+Mask[0] = core0
+Mask[1] = core1
+Mask[2] = core2
+etc
+If the bit is set ('b1) in the mask, then prefetch is disabled for
+that core when it is released from reset.
+
+core0 prefetch should not be disabled i.e. Mask[0] should never be set.
+Setting Mask[0] may lead to undefined behavior.
+
+Once disabled, prefetch remains disabled until the next reset.
+There is no function to re-enable prefetch.

+Falcon boot option
+------------------
+Falcon boot is a short cut boot method for SD/eMMC targets. It skips loading the
+RAM version U-Boot. Instead, it loads FIT image and boot directly to Linux.
+CONFIG_SPL_OS_BOOT enables falcon boot. CONFIG_SPL_LOAD_FIT enables the FIT
+image support (also need CONFIG_SPL_OF_LIBFDT, CONFIG_SPL_FIT and optionally
+CONFIG_SPL_GZIP).
+
+To enable falcon boot, a hook function spl_start_uboot() returns 0 to indicate
+booting U-Boot is not the first choice. The kernel FIT image needs to be put
+at CONFIG_SYS_MMCSD_RAW_MODE_KERNEL_SECTOR. SPL mmc driver reads the header to
+determine if this is a FIT image. If true, FIT image components are parsed and
+copied or decompressed (if applicable) to their destinations. If FIT image is
+not found, normal U-Boot flow will follow.
+
+An important part of falcon boot is to prepare the device tree. A normal U-Boot
+does FDT fixups when booting Linux. For falcon boot, Linux boots directly from
+SPL, skipping the normal U-Boot. The device tree has to be prepared in advance.
+A command "spl export" should be called under the normal RAM version U-Boot.
+It is equivalent to go through "bootm" step-by-step until device tree fixup is
+done. The device tree in memory is the one needed for falcon boot. Falcon boot
+flow suggests to save this image to SD/eMMC at the location pointed by macro
+CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTOR, with maximum size specified by macro
+CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTORS. However, when FIT image is used for
+Linux, the device tree stored in FIT image overwrites the memory loaded by spl
+driver from these sectors. We could change this loading order to favor the
+stored sectors. But when secure boot is enabled, these sectors are used for
+signature header and needs to be loaded before the FIT image. So it is important
+to understand the device tree in FIT image should be the one actually used, or
+leave it absent to favor the stored sectors. It is easier to deploy the FIT
+image with embedded static device tree to multiple boards.
+
+Macro CONFIG_SYS_SPL_ARGS_ADDR serves two purposes. One is the pointer to load
+the stored sectors to. Normally this is the static device tree. The second
+purpose is the memory location of signature header for secure boot. After the
+FIT image is loaded into memory, it is validated against the signature header
+before individual components are extracted (and optionally decompressed) into
+their final memory locations, respectively. After the validation, the header
+is no longer used. The static device tree is copied into this location. So
+this macro is passed as the location of device tree when booting Linux.
+
+Steps to prepare static device tree
+-----------------------------------
+To prepare the static device tree for Layerscape boards, it is important to
+understand the fixups in U-Boot. Memory size and location, as well as reserved
+memory blocks are added/updated. Ethernet MAC addressed are updated. FMan
+microcode (if used) is embedded in the device tree. Kernel command line and
+initrd information are embedded. Others including CPU status, boot method,
+Ethernet port status, etc. are also updated.
+
+Following normal booting process, all variables are set, all images are loaded
+before "bootm" command would be issued to boot, run command
+
+spl export fdt <address>
+
+where the address is the location of FIT image. U-Boot goes through the booting
+process as if "bootm start", "bootm loados", "bootm ramdisk"... commands but
+stops before "bootm go". There we have the fixed-up device tree in memory.
+We can check the device tree header by these commands
+
+fdt addr <fdt address>
+fdt header
+
+Where the fdt address is the device tree in memory. It is printed by U-Boot.
+It is useful to know the exact size. One way to extract this static device
+tree is to save it to eMMC/SD using command in U-Boot, and extract under Linux
+with these commands, repectively
+
+mmc write <address> <sector> <sectors>
+dd if=/dev/mmcblk0 of=<filename> bs=512 skip=<sector> count=<sectors>
+
+Note, U-Boot takes values as hexadecimals while Linux takes them as decimals by
+default. If using NAND or other storage, the commands are slightly different.
+When we have the static device tree image, we can re-make the FIT image with
+it. It is important to specify the load addresses in FIT image for every
+components. Otherwise U-Boot cannot load them correctly.
+
+Generate FIT image with static device tree
+------------------------------------------
+Example:
+
+/dts-v1/;
+
+/ {
+ description = "Image file for the LS1043A Linux Kernel";
+ #address-cells = <1>;
+
+ images {
+ kernel {
+ description = "ARM64 Linux kernel";
+ data = /incbin/("./arch/arm64/boot/Image.gz");
+ type = "kernel";
+ arch = "arm64";
+ os = "linux";
+ compression = "gzip";
+ load = <0x80080000>;
+ entry = <0x80080000>;
+ };
+ fdt-1 {
+ description = "Flattened Device Tree blob";
+ data = /incbin/("./fsl-ls1043ardb-static.dtb");
+ type = "flat_dt";
+ arch = "arm64";
+ compression = "none";
+ load = <0x90000000>;
+ };
+ ramdisk {
+ description = "LS1043 Ramdisk";
+ data = /incbin/("./rootfs.cpio.gz");
+ type = "ramdisk";
+ arch = "arm64";
+ os = "linux";
+ compression = "none";
+ load = <0xa0000000>;
+ };
+ };
+
+ configurations {
+ default = "config-1";
+ config-1 {
+ description = "Boot Linux kernel";
+ kernel = "kernel";
+ fdt = "fdt-1";
+ ramdisk = "ramdisk";
+ loadables = "fdt", "ramdisk";
+ };
+ };
+};
+
+The "loadables" is not optional. It tells SPL which images to load into memory.
+
+Falcon mode with QSPI boot
+--------------------------
+To use falcon mode with QSPI boot, SPL needs to be enabled. Similar to SD or
+NAND boot, a RAM version full feature U-Boot is needed. Unlike SD or NAND boot,
+SPL with QSPI doesn't need to combine SPL image with RAM version image. Two
+separated images are used, u-boot-spl.pbl and u-boot.img. The former is SPL
+image with RCW and PBI commands to load the SPL payload into On-Chip RAM. The
+latter is RAM version U-Boot in FIT format (or legacy format if FIT is not
+used).
+
+Other things to consider
+-----------------------
+Falcon boot skips a lot of initialization in U-Boot. If Linux expects the
+hardware to be initialized by U-Boot, the related code should be ported to SPL
+build. For example, if Linux expect Ethernet PHY to be initialized in U-Boot
+(which is not a common case), the PHY initialization has to be included in
+falcon boot. This increases the SPL image size and should be handled carefully.
+If Linux has PHY driver enabled, it still depends on the correct MDIO bus setup
+in U-Boot. Normal U-Boot sets the MDC ratio to generate a proper clock signal.

+DDR Layout
+============
+Entire DDR region splits into two regions.
+ - Region 1 is at address 0x8000_0000 to 0xffff_ffff.
+ - Region 2 is at 0x80_8000_0000 to the top of total memory,
+ for example 16GB, 0x83_ffff_ffff.
+
+All DDR memory is marked as cache-enabled.
+
+When MC and Debug server is enabled, they carve 512MB away from the high
+end of DDR. For example, if the total DDR is 16GB, it shrinks to 15.5GB
+with MC and Debug server enabled. Linux only sees 15.5GB.
+
+The reserved 512MB layout looks like
+
+ +---------------+ <-- top/end of memory
+ | 256MB | debug server
+ +---------------+
+ | 256MB | MC
+ +---------------+
+ | ... |
+
+MC requires the memory to be aligned with 512MB, so even debug server is
+not enabled, 512MB is reserved, not 256MB.
+
+Flash Layout
+============
+
+(1) A typical layout of various images (including Linux and other firmware images)
+ is shown below considering a 32MB NOR flash device present on most
+ pre-silicon platforms (simulator and emulator):

+
+Environment Variables
+=====================
+mcboottimeout: MC boot timeout in milliseconds. If this variable is not defined
+ the value CONFIG_SYS_LS_MC_BOOT_TIMEOUT_MS will be assumed.
+
+mcmemsize: MC DRAM block size in hex. If this variable is not defined, the value
+ CONFIG_SYS_LS_MC_DRAM_BLOCK_MIN_SIZE will be assumed.
+
+mcinitcmd: This environment variable is defined to initiate MC and DPL deployment
+ from the location where it is stored(NOR, NAND, SD, SATA, USB)during
+ u-boot booting.If this variable is not defined then MC_BOOT_ENV_VAR
+ will be null and MC will not be booted and DPL will not be applied
+ during U-boot booting.However the MC, DPC and DPL can be applied from
+ console independently.
+ The variable needs to be set from the console once and then on
+ rebooting the parameters set in the variable will automatically be
+ executed. The commmand is demostrated taking an example of mc boot
+ using NOR Flash i.e. MC, DPL, and DPC is stored in the NOR flash:
+
+ cp.b 0xa0000000 0x580300000 $filesize
+ cp.b 0x80000000 0x580800000 $filesize
+ cp.b 0x90000000 0x580700000 $filesize
+
+ setenv mcinitcmd 'fsl_mc start mc 0x580300000 0x580800000'
+
+ If only linux is to be booted then the mcinitcmd environment should be set as
+
+ setenv mcinitcmd 'fsl_mc start mc 0x580300000 0x580800000;fsl_mc apply DPL 0x580700000'
+
+ Here the addresses 0xa0000000, 0x80000000, 0x80000000 are of DDR to where
+ MC binary, DPC binary and DPL binary are stored and 0x580300000, 0x580800000
+ and 0x580700000 are addresses in NOR where these are copied. It is to be
+ noted that these addresses in 'fsl_mc start mc 0x580300000 0x580800000;fsl_mc apply DPL 0x580700000'
+ can be replaced with the addresses of DDR to
+ which these will be copied in case of these binaries being stored in other
+ devices like SATA, USB, NAND, SD etc.
+
+Booting from NAND
+-------------------
+Booting from NAND requires two images, RCW and u-boot-with-spl.bin.
+The difference between NAND boot RCW image and NOR boot image is the PBI
+command sequence. Below is one example for PBI commands for LS2085AQDS which
+uses NAND device with 2KB/page, block size 128KB.
+
+1) CCSR 4-byte write to 0x00e00404, data=0x00000000
+2) CCSR 4-byte write to 0x00e00400, data=0x1800a000
+The above two commands set bootloc register to 0x00000000_1800a000 where
+the u-boot code will be running in OCRAM.
+
+3) Block Copy: SRC=0x0107, SRC_ADDR=0x00020000, DEST_ADDR=0x1800a000,
+BLOCK_SIZE=0x00014000
+This command copies u-boot image from NAND device into OCRAM. The values need
+to adjust accordingly.
+
+SRC should match the cfg_rcw_src, the reset config pins. It depends
+ on the NAND device. See reference manual for cfg_rcw_src.
+SRC_ADDR is the offset of u-boot-with-spl.bin image in NAND device. In
+ the example above, 128KB. For easy maintenance, we put it at
+ the beginning of next block from RCW.
+DEST_ADDR is fixed at 0x1800a000, matching bootloc set above.
+BLOCK_SIZE is the size to be copied by PBI.
+
+RCW image should be written to the beginning of NAND device. Example of using
+u-boot command
+
+nand write <rcw image in memory> 0 <size of rcw image>
+
+To form the NAND image, build u-boot with NAND config, for example,
+ls2080aqds_nand_defconfig. The image needed is u-boot-with-spl.bin.
+The u-boot image should be written to match SRC_ADDR, in above example 0x20000.
+
+nand write <u-boot image in memory> 200000 <size of u-boot image>
+
+With these two images in NAND device, the board can boot from NAND.
+
+Another example for LS2085ARDB boards,
+
+1) CCSR 4-byte write to 0x00e00404, data=0x00000000
+2) CCSR 4-byte write to 0x00e00400, data=0x1800a000
+3) Block Copy: SRC=0x0119, SRC_ADDR=0x00080000, DEST_ADDR=0x1800a000,
+BLOCK_SIZE=0x00014000
+
+nand write <rcw image in memory> 0 <size of rcw image>
+nand write <u-boot image in memory> 80000 <size of u-boot image>
+
+Notice the difference from QDS is SRC, SRC_ADDR and the offset of u-boot image
+to match board NAND device with 4KB/page, block size 512KB.
+
+Note, LS2088A and LS1088A don't support booting from NAND.
+
+Booting from SD/eMMC
+-------------------
+Booting from SD/eMMC requires two images, RCW and u-boot-with-spl.bin.
+The difference between SD boot RCW image and QSPI-NOR boot image is the
+PBI command sequence. Below is one example for PBI commands for RDB
+and QDS which uses SD device with block size 512. Block location can be
+calculated by dividing offset with block size.
+
+1) Block Copy: SRC=0x0040, SRC_ADDR=0x00100000, DEST_ADDR=0x1800a000,
+BLOCK_SIZE=0x00016000
+
+This command copies u-boot image from SD device into OCRAM. The values
+need to adjust accordingly for SD/eMMC
+
+SRC should match the cfg_rcw_src, the reset config pins.
+ The value for source(SRC) can be 0x0040 or 0x0041
+ depending upon SD or eMMC.
+SRC_ADDR is the offset of u-boot-with-spl.bin image in SD device.
+ In the example above, 1MB. This is same as QSPI-NOR.
+DEST_ADDR is configured at 0x1800a000, matching bootloc set above.
+BLOCK_SIZE is the size to be copied by PBI.
+
+2) CCSR 4-byte write to 0x01e00404, data=0x00000000
+3) CCSR 4-byte write to 0x01e00400, data=0x1800a000
+The above two commands set bootloc register to 0x00000000_1800a000 where
+the u-boot code will be running in OCRAM.
+
+
+RCW image should be written at 8th block of device(SD/eMMC). Example of
+using u-boot command
+
+mmc erase 0x8 0x10
+mmc write <rcw image in memory> 0x8 <size of rcw in block count typical value=10>
+
+To form the SD-Boot image, build u-boot with SD config, for example,
+ls1088ardb_sdcard_qspi_defconfig. The image needed is u-boot-with-spl.bin.
+The u-boot image should be written to match SRC_ADDR, in above example
+offset 0x100000 in other work it means block location 0x800
+
+mmc erase 0x800 0x1800
+mmc write <u-boot image in memory> 0x800 <size of u-boot image in block count>
+
+With these two images in SD/eMMC device, the board can boot from SD/eMMC.

+Errata A009635
+---------------
+If the core runs at higher than x3 speed of the platform, there is
+possiblity about sev instruction to getting missed by other cores.
+This is because of SoC Run Control block may not able to sample
+the EVENTI(Sev) signals.
+
+Workaround: Configure Run Control and EPU to periodically send out EVENTI signals to
+wake up A57 cores
+
+Errata workaround uses Env variable "a009635_interval_val". It uses decimal
+value.
+- Default value of env variable is platform clock (MHz)
+
+- User can modify default value by updating the env variable
+ setenv a009635_interval_val 600; saveenv;
+ It configure platform clock as 600 MHz
+
+- Env variable as 0 signifies no workaround

+
+Booting from QSPI
+-------------------
+Booting from QSPI requires two images, RCW and u-boot-dtb.bin.
+The difference between QSPI boot RCW image and NOR boot image is the PBI
+command sequence for setting the boot location pointer. It's should point
+to the address for u-boot in QSPI flash.
+
+RCW image should be written to the beginning of QSPI flash device.
+Example of using u-boot command
+
+=> sf probe 0:0
+SF: Detected S25FL256S_64K with page size 256 Bytes, erase size 64 KiB, total 32 MiB
+=> sf erase 0 +<size of rcw image>
+SF: 65536 bytes @ 0x0 Erased: OK
+=> sf write <rcw image in memory> 0 <size of rcw image>
+SF: 164 bytes @ 0x0 Written: OK
+
+To get the QSPI image, build u-boot with QSPI config, for example,
+<board_name>_qspi_defconfig. The image needed is u-boot-dtb.bin.
+The u-boot image should be written to 0x10000(but 0x1000 for LS1043A, LS2080A).
+
+=> sf probe 0:0
+SF: Detected S25FL256S_64K with page size 256 Bytes, erase size 64 KiB, total 32 MiB
+=> sf erase 10000 +<size of u-boot image>
+SF: 589824 bytes @ 0x10000 Erased: OK
+=> sf write <u-boot image in memory> 10000 <size of u-boot image>
+SF: 580966 bytes @ 0x10000 Written: OK
+
+With these two images in QSPI flash device, the board can boot from QSPI.
