[Anthony PERARD <anthony.perard@citrix.com>]

Patch series available in this git branch:
https://xenbits.xen.org/git-http/people/aperard/ovmf.git br.platform-xen-pvh-v5

Changes in v5:
- patch 23 got a rework of the lapic range skipping
- small fixups in patch 20, 22, 23, 31, 32, 33.
  see notes for detail.

Hi,

I've started to create a Xen specific platform, in OvmfPkg/XenOvmf.dsc
with the goal to make it work on both Xen HVM and Xen PVH.

The first few patches only create the platform and duplicate some code from
OvmfPkg and the later patches makes OVMF boot in a Xen PVH guest and can boot
a Linux guest.

After this patch series, I'd like to wait a bit before removing Xen support
from the OvmfPkg*.dsc, to allow time to switch to the new Xen only platform,
maybe 1 year.

To build and boot:

To build, simply run OvmfPkg/build.sh -p OvmfPkg/OvmfXen.dsc
Then use OVMF.fd as a kernel of a pvh guest config file (with xl/libxl).
