| 2 | This file contains basic information on the port of U-Boot to IPHASE4539 |
| 3 | (Interphase 4539 T1/E1/J1 PMC Communications Controller). |
| 4 | All the changes fit in the common U-Boot infrastructure, providing a new |
| 5 | IPHASE4539-specific entry in makefiles. To build U-Boot for IPHASE4539, |
| 6 | type "make IPHASE4539_config", edit the "include/config_IPHASE4539.h" |
| 7 | file if necessary, then type "make". |

| 10 | Common file modifications: |
| 11 | -------------------------- |
| 12 | |
| 13 | The following common files have been modified by this project: |
| 14 | (starting from the ppcboot-1.1.5/ directory) |
| 15 | |
| 16 | MAKEALL - IPHASE4539 entry added |
| 17 | Makefile - IPHASE4539_config entry added |
| 18 | |
| 19 | |
| 20 | New files: |
| 21 | ---------- |
| 22 | |
| 23 | The following new files have been added by this project: |
| 24 | (starting from the ppcboot-1.1.5/ directory) |
| 25 | |
| 26 | board/iphase4539/ - board-specific directory |
| 27 | board/iphase4539/Makefile - board-specific makefile |
| 28 | board/iphase4539/config.mk - config file |
| 29 | board/iphase4539/flash.c - flash driver (for AM29LV033C) |
| 30 | board/iphase4539/ppcboot.lds - linker script |
| 31 | board/iphase4539/iphase4539.c - ioport and memory initialization |
| 32 | include/config_IPHASE4539.h - main configuration file |
| 33 | |
| 34 | |
| 35 | New configuration options: |
| 36 | -------------------------- |
| 37 | |
| 38 | CONFIG_IPHASE4539 |
| 39 | |
| 40 | Main board-specific option (should be defined for IPHASE4539). |
| 41 | |
| 42 | |
| 43 | Acceptance criteria tests: |
| 44 | -------------------------- |
| 45 | |
| 46 | The following tests have been conducted to validate the port of U-Boot |
| 47 | to IPHASE4539: |
| 48 | |
| 49 | 1. Operation on serial console: |
| 50 | |
| 51 | With SMC1 defined as console in the main configuration file, the U-Boot |
| 52 | output appeared on the serial terminal connected to the 2.5mm stereo jack |
| 53 | connector as follows: |
| 54 | |
