[0/9] introduce name service announcement rpmsg driver

Message

The NS announcement is implemented by several backends, but could be
considered as part the RPMsg protocol. 
In this case it should be managed as a reserved rpmsg service and so
implemented on top of the rpmsg protocol.

This series introduces the rpmsg_ns driver that handles the name service
announcement. The virtio backend is updated in consequence to use this
service.

Applies cleanly on Bjorn rpmsg-next branch (ddd1930d6e3e)

Arnaud Pouliquen (9):
  rpmsg: virtio: rename rpmsg_create_channel
  rpmsg: core: add channel creation internal API
  rpmsg: virtio: add rpmsg channel device ops
  rpmsg: define the name service announcement as reserved address
  rpmsg: introduce reserved rpmsg driver for ns announcement
  rpmsg: virtio: use rpmsg ns device for the ns announcement
  rpmsg: ns: add name service announcement service
  rpmsg: virtio: use rpmsg_ns driver to manage ns announcement
  rpmsg: ns: name service announcement endianness

I have started to review this set, comments will be spread over a few days. 

Thanks,
