    remoteproc: remove the single rpmsg vdev limitation · 7a186941
    Ohad Ben-Cohen authored
    Now that the resource table supports publishing a virtio device
    in a single resource entry, firmware images can start supporting
    more than a single vdev.
    
    This patch removes the single vdev limitation of the remoteproc
    framework so multi-vdev firmwares can be leveraged: VDEV resource
    entries are parsed when the rproc is registered, and as a result
    their vrings are set up and the virtio devices are registered
    (and they go away when the rproc goes away).
    
    Moreover, we no longer only support VIRTIO_ID_RPMSG vdevs; any
    virtio device type goes now. As a result, there's no more any
    rpmsg-specific APIs or code in remoteproc: it all becomes generic
    virtio handling.
