| 2 | This file contains basic information on the port of U-Boot to TQM8260. | |
| 3 | All the changes fit in the common U-Boot infrastructure, providing a | |
| 4 | new TQM8260-specific entry in makefiles. To build U-Boot for TQM8260, | |
| 5 | type "make TQM8260_config", edit the "include/config_TQM8260.h" file | |
| 6 | if necessary, then type "make". | |

| 9 | Common file modifications: | |
| 10 | -------------------------- | |
| 11 | ||
| 12 | The following common files have been modified by this project: | |
| 13 | (starting from the ppcboot-0.9.3/ directory) | |
| 14 | ||
| 15 | MAKEALL - TQM8260 entry added | |
| 16 | Makefile - TQM8260_config entry added | |
| 17 | cpu/mpc8260/Makefile - soft_i2c.o module added | |
| 18 | cpu/mpc8260/ether_scc.c - TQM8260-specific definitions added, an obvious | |
| 19 | bug fixed (fcr -> scr) | |
| 20 | cpu/mpc8260/ether_fcc.c - TQM8260-specific definitions added | |
| 21 | include/flash.h - added definitions for the AM29LV640D Flash chip | |
| 22 | ||
| 23 | ||
| 24 | New files: | |
| 25 | ---------- | |
| 26 | ||
| 27 | The following new files have been added by this project: | |
| 28 | (starting from the ppcboot-0.9.3/ directory) | |
| 29 | ||
| 30 | board/tqm8260/ - board-specific directory | |
| 31 | board/tqm8260/Makefile - board-specific makefile | |
| 32 | board/tqm8260/config.mk - config file | |
| 33 | board/tqm8260/flash.c - flash driver (for AM29LV640D) | |
| 34 | board/tqm8260/ppcboot.lds - linker script | |
| 35 | board/tqm8260/tqm8260.c - ioport and memory initialization | |
| 36 | cpu/mpc8260/soft_i2c.c - software i2c EEPROM driver | |
| 37 | include/config_TQM8260.h - main configuration file | |
| 38 | ||
| 39 | ||
| 40 | New configuration options: | |
| 41 | -------------------------- | |
| 42 | ||
| 43 | CONFIG_TQM8260 | |
| 44 | ||
| 45 | Main board-specific option (should be defined for TQM8260). | |
| 46 | ||
| 47 | CONFIG_82xx_CONS_SMC1 | |
| 48 | ||
| 49 | If defined, SMC1 will be used as the console | |
| 50 | ||
| 51 | CONFIG_82xx_CONS_SMC2 | |
| 52 | ||
| 53 | If defined, SMC2 will be used as the console | |
| 54 | ||
| 6d0f6bcf | 55 | CONFIG_SYS_INIT_LOCAL_SDRAM |
| e2211743 WD |
56 | |
| 57 | If defined, the SDRAM on the local bus will be initialized and | |
| 58 | mapped at BR2. | |
| 59 | ||
| 60 | ||
| 61 | Acceptance criteria tests: | |
| 62 | -------------------------- | |
| 63 | ||
| 64 | The following tests have been conducted to validate the port of U-Boot | |
| 65 | to TQM8260: | |
| 66 | ||
| 67 | 1. Operation on serial console: | |
| 68 | ||
| 69 | With the CONFIG_82xx_CONS_SMC1 option defined in the main configuration file, | |
| 70 | the U-Boot output appeared on the serial terminal connected to COM1 as | |
| 71 | follows: | |

| 399 | Patch per Mon, 06 Aug 2001 17:57:27: | |
| 400 | ||
| 401 | - upgraded Flash support (added support for the following chips: | |
| 402 | AM29LV800T/B, AM29LV160T/B, AM29DL322T/B, AM29DL323T/B) | |
| 403 | - BCR tweakage for the 8260 bus mode | |
| 404 | - SIUMCR tweakage enabling the MI interrupt (IRQ7) | |
| 405 | ||
| 406 | To simplify switching between the bus modes, a new configuration | |
| 407 | option (CONFIG_BUSMODE_60x) has been added to the "config_TQM8260.h" | |
| 408 | file. If it is defined, BCR will be configured for the 60x mode, | |
| 409 | otherwise - for the 8260 mode. | |
| 410 | ||
| 411 | Concerning the SIUMCR modification: it's hard to predict whether it | |
| 412 | will induce any problems on the other (60x mode) board. However, the | |
| 413 | problems (if they appear) should be easy to notice - if the board | |
| 414 | does not boot, it's most likely caused by the DPPC configuration in | |
| 415 | SIUMCR. |
