[Xen-devel] [PATCHv4 00/04] arm: pass a device tree to dom0

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

Note 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 since v3:
  - dropped already applied patches
  - tweaked set_memory_reg() to be a bit more readable.

Changes since v2:
  - dropped already applied patches
  - fix crash on boot if bootargs is missing
  - allow space in dom0's dtb for the mem reserve entry
  - bail if dom0's dtb couldn't be created
  - new patch to print warning if a node is nested too deep

Changes since v1:
  - coding style
  - move libfdt headers
  - added myself as device tree maintainer
  - fix potential infinite loop when assigning mem
  - check dtb destination more carefully
  - minor updates for clarity
