================================================================================
0. What's this?
	This file contains status information for the port of U-Boot to the
	Renesas SuperH series of CPUs.

================================================================================
1. Overview
12
	SuperH has an original boot loader. However, source code is dirty, and
13
	maintenance is not done.
14 15
	To improve sharing and the maintenance of the code, Nobuhiro Iwamatsu
	started the porting to u-boot in 2007.

	** README **
		In SuperH, S-record and binary of made u-boot work on the memory.
80 81
		When u-boot is written in the flash, it is necessary to change the
		address by using 'objcopy'.
82
		ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec

================================================================================
4. Compiler
86
	You can use the following of u-boot to compile.
87 88 89 90 91 92 93 94 95
		- SuperH Linux Open site
			http://www.superh-linux.org/
		- KPIT GNU tools

================================================================================
5. Future
	I plan to support the following CPUs and boards.
		5.1. CPUs
96
			- SH7751R(SH4)
97
			- SH7785(SH4)
98

99 100 101 102
		5.2. Boards
