| 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) | |

| cp - memory copy | |
| cmp - memory compare | |
| crc32 - checksum calculation | |
| base - print or set address offset | |
| printenv- print 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. |
