      5 ================================================================================
      6 0. What's this?
      7 	This file contains status information for the port of U-Boot to the
      8 	Renesas SuperH series of CPUs.
      9 
     10 ================================================================================
     11 1. Overview
     12 	SuperH has an original boot loader. However, source code is dirty, and
     13 	maintenance is not done.
     14 	To improve sharing and the maintenance of the code, Nobuhiro Iwamatsu
     15 	started the porting to u-boot in 2007.
     16 
     17 ================================================================================
     18 2. Supported CPUs
     19 
     20 	2.1. Renesas SH7750/SH7750R
     21 		This CPU has the SH4 core.
     22 
     23 	2.2. Renesas SH7722
     24 		This CPU has the SH4AL-DSP core.
     25 
     26 	2.3. Renesas SH7720
     27 		This CPU has the SH3 core.
     28 
     29 	2.4. Renesas SH7710/SH7712
     30 		This CPU has the SH3-DSP core and Ethernet controller.
     31 
     32 	2.5. Renesas SH7780
     33 		This CPU has the SH4A core.

     77 
     78 	** README **
     79 		In SuperH, S-record and binary of made u-boot work on the memory.
     80 		When u-boot is written in the flash, it is necessary to change the
     81 		address by using 'objcopy'.
     82 		ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec
     83 
     84 ================================================================================
     85 4. Compiler
     86 	You can use the following of u-boot to compile.
     87 		- SuperH Linux Open site
     88 			http://www.superh-linux.org/
     89 		- KPIT GNU tools
