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 for-next branch (ca69dba7f13a)
Main updates from V1 to V2:
- Integrate Mathieu's comments:
- rework the rpmsg_create_channel and rpmsg_release_channel error management.
- merge patch "[9/9] rpmsg: ns: name service announcement endianness"
in other pathes.
