+ 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 ;-)
