+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/powerpc/cpu/mpc8260/Makefile - soft_i2c.o module added
+arch/powerpc/cpu/mpc8260/ether_scc.c - TQM8260-specific definitions added, an obvious
+ bug fixed (fcr -> scr)
+arch/powerpc/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/powerpc/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'

+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.
