[PATCH v3 0/4] hvmloader: make OVMF work with Xen

[Wei Liu <wei.liu2@citrix.com>]

This is version 3 of Xen side patches.

RFC tag is dropped because we reach consensus on what to pass on to OVMF,
though OVMF side patches are sitll awaiting review.

Release wise, I think this patch set should do more good than harm. It only
affects OVMF, which we cannot make it worse - it was broken since long.

Wei.

Changes in V3:
* move seabios_info to common code
* e820 entry number is 16 again, one can bump it when necessary
* reserve low reset vector in E820 map in OVMF

Changes in V2:
* ovmf_info is now almost the same as seabios_info
* bump e820 entry number to 128
* modify build_e820_table to avoid BIOS region reservation if there's none

Wei Liu (4):
  hvmloader/ovmf: remove hardcoded OVMF loading location
  hvmloader/ovmf: show OVMF_BEGIN as bios address
  hvmloader/ovmf: setup BIOS info for OVMF
  hvmloader/ovmf: setup E820 map
