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' => ------------------------------------------------------------------------------ 2.

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.
