| 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. |
