U-Boot for Renesas SuperH
|
||||
Last update 01/18/2008 by Nobuhiro Iwamatsu
|
||||
|
||||
================================================================================
|
||||
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
|
||||
This CPU has the SH4 core.
|
||||
|
||||
2.2. Renesas SH7722
|
||||
This CPU has the SH4AL-DSP core.
|
||||
|
||||
2.3. Renesas SH7780
|
||||
This CPU has the SH4A core.
|
||||
|
||||
================================================================================
|
||||
3. Supported Boards
|
||||
|
||||
3.1. Hitachi UL MS7750SE01/MS7750RSE01
|
||||
Board specific code is in board/ms7750se
|
||||
To use this board, type "make ms7750se_config".
|
||||
Support devices are :
|
||||
- SCIF
|
||||

|
||||
|
||||
3.2. Hitachi UL MS7722SE01
|
||||
Board specific code is in board/ms7722se
|
||||
To use this board, type "make ms7722se_config".
|
||||
Support devices are :
|
||||
- SCIF
|
||||
- SDRAM
|
||||
- NOR Flash
|
||||
- Marubun PCMCIA
|
||||
- SMC91x ethernet
|
||||
|
||||
3.2. Hitachi UL MS7720ERP01
|
||||
Board specific code is in board/ms7720se
|
||||
To use this board, type "make ms7720se_config".
|
||||
Support devices are :
|
||||
- SCIF
|
||||
- SDRAM
|
||||
- NOR Flash
|
||||
- Marubun PCMCIA
|
||||
|
||||
3.3. Renesas R7780MP
|
||||
Board specific code is in board/r7780mp
|
||||
To use this board, type "make r7780mp_config".
|
||||
Support devices are :
|
||||
- SCIF
|
||||
- DDR-SDRAM
|
||||
- NOR Flash
|
||||
- Compact Flash
|
||||
- ASIX ethernet
|
||||
- SH7780 PCI bridge
|
||||
- RTL8110 ethernet
|
||||
|
||||
** 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
|
||||
- SH7751R(SH4)
|
||||
|
||||
5.2. Boards
|
||||
- Many boards ;-)
