Bsp and CPU porting

[James Yates]

Many Thanks Jay.

You are an absolute superstar. I now have a bsp and cpu port that wants
to compile. A few minor errors in the actual port but it is atleast
trying to build.

	Many Thanks for your help.

register addresses etc as required.

Did you add your CPU to libcpu/sh/configure.ac and your BSP to
libbsp/sh/acinclude.m4? After modifying those files, you need to run
bootstrap.

Before running bootstrap, make sure you have the right versions of
automake
and autoconf. Then, while in the libcpu/sh and libbsp/sh directories,
run '../../../../../bootstrap -c' and '../../../../../bootstrap'
