[Xen-devel] [PATCH 2 of 3] Enable UEFI BIOS(OVMF) support in Xen-unstable HVM

[Bei Guan <gbtju85@xxxxxxxxx>]

# HG changeset patch
# User gbtju85@xxxxxxxxx
#

Xen: Expose hvmloader/bios in libxl and xend.

Exposes the hvmloader/bios xenstore key in libxl and xend,
so firmware loaded can be overriden (choices: rombios, seabios
ovmf-ia32, ovmf-x64).
