Tsirkin" 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 uncompres= sed kernel using the x86/HVM direct boot ABI. Patches 1 and 2 are to prepare the PVH option rom, moving common function= s in the new headers. Patch 3 adds the new PVH option rom. Patch 4 uses it wh= en we are booting an uncompressed kernel using the x86/HVM direct boot ABI. Pat= ch 5 adds the support of loading the initrd in the PVH option rom.
