- remove trailing white space, trailing empty lines, C++ comments, etc.
- split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)
* Patches by Kenneth Johansson, 25 Jun 2003:
- major rework of command structure
(work done mostly by Michal Cendrowski and Joakim Kristiansen)

This file contains basic information on the port of U-Boot to TQM8260.
|
|
All the changes fit in the common U-Boot infrastructure, providing a
|
|
new TQM8260-specific entry in makefiles. To build U-Boot for TQM8260,
|
|
type "make TQM8260_config", edit the "include/config_TQM8260.h" file
|
|
if necessary, then type "make".
|
|
|
|
|
|
Common file modifications:
|
|
--------------------------
|
|
|
|
The following common files have been modified by this project:
|
|
(starting from the ppcboot-0.9.3/ directory)
|
|
|
|
MAKEALL - TQM8260 entry added
|
|
Makefile - TQM8260_config entry added
|
|
cpu/mpc8260/Makefile - soft_i2c.o module added
|
|
cpu/mpc8260/ether_scc.c - TQM8260-specific definitions added, an obvious
|
|
bug fixed (fcr -> scr)
|
|
cpu/mpc8260/ether_fcc.c - TQM8260-specific definitions added
|
|
include/flash.h - added definitions for the AM29LV640D Flash chip
|
|
|
|
|
|
New files:
|
|
----------
|
|
|
|
The following new files have been added by this project:
|
|
(starting from the ppcboot-0.9.3/ directory)
|
|
|
|
board/tqm8260/ - board-specific directory
|
|
board/tqm8260/Makefile - board-specific makefile
|
|
board/tqm8260/config.mk - config file
|
|
board/tqm8260/flash.c - flash driver (for AM29LV640D)
|
|
board/tqm8260/ppcboot.lds - linker script
|
|
board/tqm8260/tqm8260.c - ioport and memory initialization
|
|
cpu/mpc8260/soft_i2c.c - software i2c EEPROM driver
|
|
include/config_TQM8260.h - main configuration file
|
|
|
|
|
|
New configuration options:
|
|
--------------------------
|
|
|
|
CONFIG_TQM8260
|
|
|
|
Main board-specific option (should be defined for TQM8260).
|
|
|
|
CONFIG_82xx_CONS_SMC1
|
|
|
|
If defined, SMC1 will be used as the console
|
|
|
|
CONFIG_82xx_CONS_SMC2
|
|
|
|
If defined, SMC2 will be used as the console
|
|
|
|
CFG_INIT_LOCAL_SDRAM
|
|
|
|
If defined, the SDRAM on the local bus will be initialized and
|
|
mapped at BR2.
|
|
|
|
|
|
Acceptance criteria tests:
|
|
--------------------------
|
|
|
|
The following tests have been conducted to validate the port of U-Boot
|
|
to TQM8260:
|
|
|
|
1. Operation on serial console:
|
|
|
|
With the CONFIG_82xx_CONS_SMC1 option defined in the main configuration file,
|
|
the U-Boot output appeared on the serial terminal connected to COM1 as
|
|
follows:
|
|
|

Patch per Mon, 06 Aug 2001 17:57:27:
|
|
|
|
- upgraded Flash support (added support for the following chips:
|
|
AM29LV800T/B, AM29LV160T/B, AM29DL322T/B, AM29DL323T/B)
|
|
- BCR tweakage for the 8260 bus mode
|
|
- SIUMCR tweakage enabling the MI interrupt (IRQ7)
|
|
|
|
To simplify switching between the bus modes, a new configuration
|
|
option (CONFIG_BUSMODE_60x) has been added to the "config_TQM8260.h"
|
|
file. If it is defined, BCR will be configured for the 60x mode,
|
|
otherwise - for the 8260 mode.
|
|
|
|
Concerning the SIUMCR modification: it's hard to predict whether it
|
|
will induce any problems on the other (60x mode) board. However, the
|
|
problems (if they appear) should be easy to notice - if the board
|
|
does not boot, it's most likely caused by the DPPC configuration in
|
|
SIUMCR.
