[Xen-devel] [PATCH 0/8] arm: initial device tree support (#3)

[David Vrabel <david.vrabel@xxxxxxxxxx>]

This series adds preliminary device tree support to Xen for ARM.

libfdt for parsing a device tree in flattened device tree (fdt) format
and added and used to find the location and size of RAM.  This info is
then used when relocating Xen and setting up the mm and heaps.

Since we don't have a bootloader when using the model the device tree
blob (DTB) is linked into .dtb section of the Xen image.  The
CONFIG_DTB_FILE make variable (set in .config or on the make command
line) gives the name of the DTB file to use.  See the wiki[1] for a
device tree for the model.

This series is also available in the device-tree-v3 branch of
git://xenbits.xen.org/people/dvrabel/xen-unstable.git

Changes since v2:

- use the CONFIG_DTB_FILE variable instead of a hardcoded path for the
  DTB file.

Changes since v1:

- map DTB in head.S using the L2 slot after the fixmap.
- new patch 8 for setting up mm/heaps.
