Re: [PATCH] arch/microblaze: add new architecture

[Stephan Linz <linz at li-pro dot net>]

Hi David, Yann, All

thank you for the fast response. Now I've seen there is a snapshot of
all the source code with latest Microblaze support:

http://git.xilinx.com/?p=microblaze-gnu.git;a=tree;f=src

Together with David's patch "config+scripts: Custom gcc, binutils, libc,
gdb version" I can start to evaluate a cutomized rebuild.


Thanks and br,
Stephan Linz
