0. What's this? |
||||||
|
This file contains status information for the port of U-Boot to the |
||||||
|
Renesas SuperH series of CPUs. |
||||||
|
|
||||||
|
================================================================================ |
||||||
|
1. Overview |
||||||
|
SuperH has an original boot loader. However, source code is dirty, and |
||||||
|
maintenance is not done. |
||||||
|
To improve sharing and the maintenance of the code, Nobuhiro Iwamatsu |
||||||
|
started the porting to u-boot in 2007. |
||||||
|
|
||||||
|
================================================================================ |
||||||
|
2. Supported CPUs |
||||||
|
|
||||||
|
2.1. Renesas SH7750/SH7750R |
||||||
|
2.2. Renesas SH7722 |
||||||
|
|
||||||
|
================================================================================ |
||||||
|
3. Supported Boards |
||||||
|
|
||||||
|
3.1. Hitachi UL MS7750SE01/MS7750RSE01 |
||||||
|
Board specific code is in board/ms7750se |
||||||
|
To use this board, type "make ms7750se_config". |
||||||
|
|
||||||
|
3.2. Hitachi UL MS7722SE01 |
||||||
|
Board specific code is in board/ms7722se |
||||||
|
To use this board, type "make ms7722se_config". |
||||||
|
|
||||||
|
** README ** |
||||||
|
In SuperH, S-record and binary of made u-boot work on the memory. |
||||||
|
When u-boot is written in the flash, it is necessary to change the |
||||||
|
address by using 'objcopy'. |
||||||
|
ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec |
||||||
|
|
||||||
|
================================================================================ |
||||||
|
4. Compiler |
||||||
|
You can use the following of u-boot to compile. |
||||||
|
- SuperH Linux Open site |
||||||
|
http://www.superh-linux.org/ |
||||||
|
- KPIT GNU tools |
||||||
|

||||||
|
|
||||||
|
================================================================================ |
||||||
|
5. Future |
||||||
|
I plan to support the following CPUs and boards. |
||||||
|
5.1. CPUs |
||||||
|
- SH7710/SH7712 (SH3) |
||||||
|
