This patch series is based on "[PATCH v3 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 the new headers. Patch 3 adds the new PVH option rom. Patch 4 uses it when we are booting an uncompressed kernel using the x86/HVM direct boot ABI. Patch 5 adds the support of loading the initrd in the PVH option rom.
