    virtio-pmem: add virtio device · 5f503cd9

    This is the implementation of virtio-pmem device. Support will require
    machine changes for the architectures that will support it, so it will
    not yet be compiled. It can be unlocked with VIRTIO_PMEM_SUPPORTED per
    machine and disabled globally via VIRTIO_PMEM.
    
    We cannot use the "addr" property as that is already used e.g. for
    virtio-pci/pci devices. And we will have e.g. virtio-pmem-pci as a proxy.
    So we have to choose a different one (unfortunately). "memaddr" it is.
    That name should ideally be used by all other virtio-* based memory
    devices in the future.
        -device virtio-pmem-pci,id=p0,bus=bux0,addr=0x01,memaddr=0x1000000...
