[Xen-devel] [PATCH 0/8] arm: pass a device tree to dom0

[David Vrabel <david.vrabel@xxxxxxxxxx>]

This series of patches makes Xen pass a (somewhat) valid device tree
to dom0.  The device tree for dom0 is the same as the one supplied to
Xen except the memory and chosen nodes are adjusted appropriately.

We don't yet make use of the device tree to map MMIO regions or setup
interrupts for the guest and we still include the UART used for Xen's
console.

Note that loading Linux using a vmlinux file is no longer supported
and the kernel must support device tree (ATAGS are no longer provided
by Xen).

It is also possible to provide the Xen and dom0 command line via the
device tree.  This isn't as useful as it seems as Xen still needs to
be rebuilt to included the updated device tree.

The instructions on the wiki[1] have been updated to reflect these
changes.

David
