| This file contains basic information on the port of U-Boot to IPHASE4539 |
| (Interphase 4539 T1/E1/J1 PMC Communications Controller). |
| All the changes fit in the common U-Boot infrastructure, providing a new |
| IPHASE4539-specific entry in makefiles. To build U-Boot for IPHASE4539, |
| type "make IPHASE4539_config", edit the "include/config_IPHASE4539.h" |
| file if necessary, then type "make". |
| |
| |
| Common file modifications: |
| -------------------------- |
| |
| The following common files have been modified by this project: |
| (starting from the ppcboot-1.1.5/ directory) |
| |
| MAKEALL - IPHASE4539 entry added |
| Makefile - IPHASE4539_config entry added |
| |
| |
| New files: |
| ---------- |
| |
| The following new files have been added by this project: |
| (starting from the ppcboot-1.1.5/ directory) |
| |
| board/iphase4539/ - board-specific directory |
| board/iphase4539/Makefile - board-specific makefile |
| board/iphase4539/config.mk - config file |
| board/iphase4539/flash.c - flash driver (for AM29LV033C) |
| board/iphase4539/ppcboot.lds - linker script |
| board/iphase4539/iphase4539.c - ioport and memory initialization |
| include/config_IPHASE4539.h - main configuration file |
| |
| |
| New configuration options: |
| -------------------------- |
| |
| CONFIG_IPHASE4539 |
| |
| Main board-specific option (should be defined for IPHASE4539). |
| |
| |
| Acceptance criteria tests: |
| -------------------------- |
| |
| The following tests have been conducted to validate the port of U-Boot |
| to IPHASE4539: |
| |
| 1. Operation on serial console: |
| |
| With SMC1 defined as console in the main configuration file, the U-Boot |
| output appeared on the serial terminal connected to the 2.5mm stereo jack |
| connector as follows: |
| |
| ------------------------------------------------------------------------------ |

| 2. Flash driver operation |
| |
| The following sequence was performed to test the "flinfo" command: |

| Note: the Hardware Configuration Word (HWC) of the 8260 is on the |
| first sector of the flash and should not be touched. The U-Boot |
| environment variables are stored on second sector and U-Boot |
| starts at the address 0xFFB00000. |

| Configure and make U-Boot: |
| |
| $ cd <path>/u-boot |
| $ make IPHASE4539_config |
| $ make dep |
| $ make |
| $ cp -p u-boot.bin /tftpboot |
| |
| Load u-boot.bin into the Flash memory at 0xffb00000. |
| |
| |
| Linux: |
| |
| Configure and make Linux: |
| |
| $ cd <patch>/linux-2.4 |
| $ make IPHASE4539_config |
| $ make oldconfig |
| $ make dep |
| $ make uImage |
| $ cp -p arch/ppc/mbxboot/uImage /tftpboot |
| |
| Load uImage via tftp and boot it. |

| Flash organisation: |
| |
| The following preliminary layout of the Flash memory |
| is defined: |
| |
| 0xff800000 ( 0 - 64 kB): Hardware Configuration Word. |
| 0xff810000 ( 64 kB - 128 kB): U-Boot Environment. |
| 0xff820000 ( 128 kB - 3 MB): RAMdisk. |
| 0xffb00000 ( 3 MB - 3328 kB): U-Boot. |
| 0xffb40000 (3328 KB - 4 MB): Linux Kernel. |
| |
