This file contains basic information on the port of U-Boot to TQM8260.All the changes fit in the common U-Boot infrastructure, providing anew TQM8260-specific entry in makefiles. To build U-Boot for TQM8260,type "make TQM8260_config", edit the "include/config_TQM8260.h" fileif 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 addedMakefile - TQM8260_config entry addedcpu/mpc8260/Makefile - soft_i2c.o module addedcpu/mpc8260/ether_scc.c - TQM8260-specific definitions added, an obvious bug fixed (fcr -> scr)cpu/mpc8260/ether_fcc.c - TQM8260-specific definitions addedinclude/flash.h - added definitions for the AM29LV640D Flash chipNew files:----------The following new files have been added by this project:(starting from the ppcboot-0.9.3/ directory)board/tqm8260/ - board-specific directoryboard/tqm8260/Makefile - board-specific makefileboard/tqm8260/config.mk - config fileboard/tqm8260/flash.c - flash driver (for AM29LV640D)board/tqm8260/ppcboot.lds - linker scriptboard/tqm8260/tqm8260.c - ioport and memory initializationcpu/mpc8260/soft_i2c.c - software i2c EEPROM driverinclude/config_TQM8260.h - main configuration fileNew 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 consoleCONFIG_82xx_CONS_SMC2 If defined, SMC2 will be used as the consoleCFG_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-Bootto 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 asfollows:------------------------------------------------------------------------------=> helpgo - start application at address 'addr'run - run commands in an environment variablebootm - boot application image from memorybootp - boot image via network using BootP/TFTP protocoltftpboot- boot image via network using TFTP protocol and env variables ipaddr and serveriprarpboot- boot image via network using RARP/TFTP protocolbootd - boot default, i.e., run 'bootcmd'loads - load S-Record file over serial lineloadb - load binary file over serial line (kermit mode)md - memory displaymm - memory modify (auto-incrementing)nm - memory modify (constant address)mw - memory write (fill)cp - memory copycmp - memory comparecrc32 - checksum calculationbase - print or set address offsetprintenv- print environment variablessetenv - set environment variablessaveenv - save environment variables to persistent storageprotect - enable or disable FLASH write protectionerase - erase FLASH memoryflinfo - print FLASH memory informationbdinfo - print Board Info structureiminfo - print header information for application imageconinfo - print console devices and informationseeprom - EEPROM sub-systemloop - infinite loop on address rangemtest - simple RAM testicache - enable or disable instruction cachedcache - enable or disable data cachereset - Perform RESET of the CPUecho - echo args to consoleversion - print monitor versionhelp - print online help? - alias for 'help'=>------------------------------------------------------------------------------2.
