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
arch/ppc/cpu/mpc8260/Makefile - soft_i2c.o module added
arch/ppc/cpu/mpc8260/ether_scc.c - TQM8260-specific definitions added, an obvious
bug fixed (fcr -> scr)
arch/ppc/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
arch/ppc/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
CONFIG_SYS_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:
------------------------------------------------------------------------------
=> 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
and env variables ipaddr and serverip
rarpboot- boot image via network using RARP/TFTP protocol
bootd - boot default, i.e., run 'bootcmd'
loads - load S-Record file over serial line
loadb - load binary file over serial line (kermit mode)
md - memory display
mm - memory modify (auto-incrementing)
nm - memory modify (constant address)
mw - memory write (fill)
cp - memory copy
cmp - memory compare
crc32 - checksum calculation
base - print or set address offset
printenv- print environment variables
setenv - set environment variables
saveenv - save environment variables to persistent storage
protect - enable or disable FLASH write protection
erase - erase FLASH memory
flinfo - print FLASH memory information
bdinfo - print Board Info structure
iminfo - print header information for application image
coninfo - print console devices and informations
eeprom - EEPROM sub-system
loop - infinite loop on address range
mtest - simple RAM test
icache - enable or disable instruction cache
dcache - enable or disable data cache
reset - Perform RESET of the CPU
echo - echo args to console
version - print monitor version
help - print online help
? - alias for 'help'
=>
------------------------------------------------------------------------------
2. Flash driver operation
The following sequence was performed to test the "flinfo" command:
------------------------------------------------------------------------------

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.
