[Xen-devel] [PATCH V1 00/29] Allow Xen to boot with a raw Device Tree

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hi,

This is the second version of this patch series. It allow Xen to boot with
a raw device tree, ie without any specific modification for Xen.

Few months ago, the patch series "Support multiple ARM platform in XEN", has
added a tree structure to handle easier the device tree. Each node can carry
metadata to specify if the node can be pass-through to Dom0. Therefore, this
patch series take advantage of the "new" Device Tree API and get a rid of
the FDT API that is currently used to build Dom0 dts and in some drivers.

Major changes since v1:
    - Add multiple commandlines patch from Andre and rebase it (mostly
      use the new helpers): http://patches.linaro.org/19356/
    - Remove and add fake node for cpus, gic and timer

All the changes can be found in each patch.

TODO list:
    - Add support for memreserve. This is needed for HDLCD framebuffer on the
    versatile express.

Cheers,
