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
Move arch/ppc to arch/powerpc As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.

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

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
rename CFG_ macros to CONFIG_SYS Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>

CONFIG_SYS_INIT_LOCAL_SDRAM
Initial revision
22 years ago
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:
------------------------------------------------------------------------------
=> help
go - start application at address 'addr'
run - run commands in an environment variable
bootm - boot application image from memory
bootp - boot image via network using BootP/TFTP protocol
tftpboot- boot image via network using TFTP protocol
* Code cleanup: - 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)

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.
