+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

+                       - 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 ;-)
