This set starts by making the RPMSG protocol transport agnostic by moving the headers it uses to generic types and using those in the current implementation. From there it re-uses the work that Arnaud published[1] to make the name service modular. The main difference with this revision is the usage of a variable (rpmsg_device::little_endian) rather than an operation to determine the byte representation of the transport layer. It is also addressing a problem that would have prevented git bisect to work properly in rpmsg_ns_cb() where the rpdev was used. In short patches 1 to 3 and patch 7 have to be reviewed again. They changed enough that I did not add RB tags to them. Patches 4 to 6 have not changed from the previous revision. Tested on stm32mp157 with the RPMSG client sample application. Applies cleanly on v5.9.
