|
|
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
|
|
http://www.kpitgnutools.com/
|
|
|
|
================================================================================
|
|
5. Future
|
|
I plan to support the following CPUs and boards.
|
|
5.1. CPUs
|
|
- SH7710/SH7712 (SH3)
|
|
- SH7780(SH4)
|
|
- SH7785(SH4)
|
|
|
|
