- 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 SH7720
- This CPU has the SH3 core.
- 2.4. Renesas SH7710/SH7712
- This CPU has the SH3-DSP core and Ethernet controller.
- 2.5. 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
- - SDRAM
- - NOR Flash
- - Marubun PCMCIA
- 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)
- - SH7785(SH4)
- 5.2. Boards
- - Many boards ;-)
