U-Boot for Renesas SuperH Last update 08/10/2007 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 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) 5.2. Boards - Many boards ;-) ================================================================================ Copyright (c) 2007 Nobuhiro Iwamatsu <iwamatsu@nigaur.org>
