The more standard 'source' command provides identical functionality to the autoscr command. Environment variable names/values on the MVBC_P, MVBML7, kmeter1, mgcoge, and km8xx boards are updated to no longer refernce 'autoscr'. The 'autoscript' and 'autoscript_uname' environment variables are also removed.

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

|
|
|
|
|
|
Linux:
|
|
|
|
Configure and make Linux:
|
|
|
|

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.
|
|
|
|
|
