| 6 | 0. What's this? |
| 7 | This file contains status information for the port of U-Boot to the |
| 8 | Renesas SuperH series of CPUs. |
| 9 | |
| 10 | ================================================================================ |
| 11 | 1. Overview |
| 12 | SuperH has an original boot loader. However, source code is dirty, and |
| 13 | maintenance is not done. |
| 14 | To improve sharing and the maintenance of the code, Nobuhiro Iwamatsu |
| 15 | started the porting to u-boot in 2007. |
| 16 | |
| 17 | ================================================================================ |
| 18 | 2. Supported CPUs |
| 19 | |
| 20 | 2.1. Renesas SH7750/SH7750R |
| 21 | 2.2. Renesas SH7722 |
| 22 | |
| 23 | ================================================================================ |
| 24 | 3. Supported Boards |
| 25 | |
| 26 | 3.1. Hitachi UL MS7750SE01/MS7750RSE01 |
| 27 | Board specific code is in board/ms7750se |
| 28 | To use this board, type "make ms7750se_config". |
| 29 | |
| 30 | 3.2. Hitachi UL MS7722SE01 |
| 31 | Board specific code is in board/ms7722se |
| 32 | To use this board, type "make ms7722se_config". |
| 33 | |
| 34 | ** README ** |
| 35 | In SuperH, S-record and binary of made u-boot work on the memory. |
| 36 | When u-boot is written in the flash, it is necessary to change the |
| 37 | address by using 'objcopy'. |
| 38 | ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec |
| 39 | |
| 40 | ================================================================================ |
| 41 | 4. Compiler |
| 42 | You can use the following of u-boot to compile. |
| 43 | - SuperH Linux Open site |
| 44 | http://www.superh-linux.org/ |
| 45 | - KPIT GNU tools |
| 46 | http://www.kpitgnutools.com/ |
| 47 | |
| 48 | ================================================================================ |
| 49 | 5. Future |
| 50 | I plan to support the following CPUs and boards. |
| 51 | 5.1. CPUs |
| 52 | - SH7710/SH7712 (SH3) |
| 53 | - SH7780(SH4) |
| 54 | - SH7785(SH4) |
| 55 | |
| 56 | 5.2. Boards |
| 57 | - Many boards ;-) |
