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

10================================================================================
111. Overview
Wolfgang Denk61fb15c52007-12-27 01:52:50 +010012 SuperH has an original boot loader. However, source code is dirty, and
Nobuhiro Iwamatsu13008082007-11-25 02:51:17 +090013 maintenance is not done.
Wolfgang Denk61fb15c52007-12-27 01:52:50 +010014 To improve sharing and the maintenance of the code, Nobuhiro Iwamatsu
15 started the porting to u-boot in 2007.

73 In SuperH, S-record and binary of made u-boot work on the memory.
Wolfgang Denk61fb15c52007-12-27 01:52:50 +010074 When u-boot is written in the flash, it is necessary to change the
75 address by using 'objcopy'.
Nobuhiro Iwamatsu13008082007-11-25 02:51:17 +090076 ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec
