[PATCH RFC 0/8] xen/arm: initial cubieboard2 support.
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.

[PATCH v3 0/7] support for cubieboard2 / sunxi processors
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.
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.
