[Xen-devel] [PATCH v4 00/27] Allow Xen to boot with a raw device tree

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hi,

This is the fourth version of this patch series. It allows 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 v2:
    - Address Ian's comment from V2. (Forgot to fix it on the V3)
    - Correct support for interrupts. Nodes with an "interrupts" property
    need to be link to the GIC.

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,
