5================================================================================
60. 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================================================================================
111. 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================================================================================
182. Supported CPUs

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

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================================================================================
854. 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
90			http://www.kpitgnutools.com/
91
92================================================================================
935. Future
94	I plan to support the following CPUs and boards.
95		5.1. CPUs
96			- SH7751R(SH4)
97			- SH7785(SH4)
98
99		5.2. Boards
100			- Many boards ;-)
