Re: [microblaze-uclinux] sources for microblaze-related software

Xilinx provides the source code for the GNU toolchains for both
microblaze and powerpc.   Look here for EDK 8.2 source:

http://www.xilinx.com/guest_resources/gnu/index.htm

I've been successful at compiling it using cygwin, but haven't tried it
under linux.  If you need a tarball for a previous release, you have to
contact Steve Wenande ( steve.wenande@xxxxxxxxxx ) to get it.  I wish we
kept the old tarballs online, but for some reason, they aren't offered.

Compiling old releases is tricky, since you generally need to use the
same version of cygwin as the original EDK release.  Fruitbat.org can
help you with old version of cygwin.
