This patchset introduces the new protocol VIRTIO_DEVICE_PROTOCOL that abstracts
the VirtIo transport layer.
It allows to enable VirtIo on devices that do not have PCI support. These
devices might use a memory mapped view of the VirtIo controller (see Appendix
X: virtio-mmio of the Virtio spec v0.9.5).
This patchset also allows to remove the duplicated PCI code over the different
VirtIo devices.
Note: The AArch64 ARM Foundation and Base models use VirtIo Block device over
VirtIo MMIO to expose block device to the ARM models.
This patchset has been validated on:
- OvmfPkg X64 with the Block, Scsi and Net Virtio devices
- AArch64 Foundation and VExpress ARM models
