See http://www.gossamer-threads.com/lists/xen/devel/297170 for some information on how to get this going. I''ve rebased and addressed the review comments. As before several of the patches are not to be applied because they can be done better using infrastructure from Julien''s "Allow Xen to boot with a raw Device Tree" patch. They are included for completeness. With

With this rebase I''ve picked up some patches from Julien which were required to do things properly, so the gic v7 and device blacklisting patches have been changed to use the proper mechanisms. Previously I was able to boot
