[Qemu-devel] [edk2 PATCH 07/12] OvmfPkg: introduce VIRTIO_MMIO_TRANSPORT_GUID

[Laszlo Ersek]

Soon there will be more than one modules (in separate packages) that need
to have an understanding about the GUID used in the VenHw() device path
nodes that describe virtio-mmio transports. Define such a GUID explicitly.

Preserve the current value (which happens to be the FILE_GUID of
ArmPlatformPkg/ArmVirtualizationPkg/VirtFdtDxe/VirtFdtDxe.inf) for
compatibility with external users.
