Message

This patch series is based on "[RFC v2 0/4] QEMU changes to do PVH boot" and
provides a PVH option rom that can be used with SeaBIOS to boot uncompressed
kernel using the x86/HVM direct boot ABI.

Patches 1 and 2 are to prepare the PVH option rom, moving common functions in a
new header.  Patch 3 adds the new PVH option rom and patch 4 uses it when we
are booting an uncompressed kernel using the x86/HVM direct boot ABI.

Stefano Garzarella (4):
  linuxboot_dma: remove duplicate definitions of FW_CFG
  linuxboot_dma: move common functions in a new header
  optionrom: add new PVH option rom
  hw/i386/pc: use PVH option rom
