| help | |
| Append an extra string to the end of your U-Boot version. | |
| This will show up on your boot log, for example. | |
| The string you set here will be appended after the contents of | |
| any files with a filename matching localversion* in your | |
| object and source tree, in that order. Your total string can | |
| be a maximum of 64 characters. | |
| config LOCALVERSION_AUTO | |
| bool "Automatically append version information to the version string" | |
| depends on !SPL_BUILD | |
| default y | |
| help | |
| This will try to automatically determine if the current tree is a | |
| release tree by looking for git tags that belong to the current | |
| top of tree revision. | |
| A string of the format -gxxxxxxxx will be added to the localversion | |
| if a git-based tree is found. The string generated by this will be | |
| appended after any matching localversion* files, and after the value | |
| set in CONFIG_LOCALVERSION. | |
| (The actual string used here is the first eight characters produced | |
| by running the command: | |
| $ git rev-parse --verify HEAD | |
| which is done within the script "scripts/setlocalversion".) | |

| Enabling this option will pass "-Os" instead of "-O2" to gcc | |
| resulting in a smaller U-Boot image. | |

| menuconfig EXPERT | |
| bool "Configure standard U-Boot features (expert users)" | |
| help | |
| This option allows certain base U-Boot options and settings | |
| to be disabled or tweaked. This is for specialized | |
| environments which can tolerate a "non-standard" U-Boot. | |
| Only use this if you really know what you are doing. | |

| This option allows to boot the new uImage structrure, | |
| Flattened Image Tree. FIT is formally a FDT, which can include | |
| images of various types (kernel, FDT blob, ramdisk, etc.) | |
| in a single blob. To boot this new uImage structure, | |
| pass the the address of the blob to the "bootm" command. | |

| config SYS_EXTRA_OPTIONS | |
| string "Extra Options (DEPRECATED)" | |
| depends on !SPL_BUILD | |
| help | |
| The old configuration infrastructure (= mkconfig + boards.cfg) | |
| provided the extra options field. If you have something like | |
| "HAS_BAR,BAZ=64", the optional options | |
| #define CONFIG_HAS | |
| #define CONFIG_BAZ 64 | |
| will be defined in include/config.h. | |
| This option was prepared for the smooth migration from the old | |
| configuration to Kconfig. Since this option will be removed sometime, | |
| new boards should not use this option. | |
