- SuperH
- ======
- What's this?
- ------------
- This file contains status information for the port of U-Boot to the
- Renesas SuperH series of CPUs.
- 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.
- Supported CPUs
- --------------
- Renesas SH7750/SH7750R
- ^^^^^^^^^^^^^^^^^^^^^^
- This CPU has the SH4 core.
- Renesas SH7722
- ^^^^^^^^^^^^^^
- This CPU has the SH4AL-DSP core.
- Supported Boards
- ----------------
- 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
- 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
- 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
- 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
- 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/>`_
- Future
- ------
- I plan to support the following CPUs and boards.
- CPUs
- ^^^^
- - SH7751R(SH4)
- Boards
- ^^^^^^
- Many boards ;-)
