For those finding this thread and wondering how hard it'd be to get official support...
You'll probably need to find a way to incorporate the latest xradio driver into the OpenWRT/LEDE builds.
The current kernel is >3.4 (what Orange Pi has sources for) and the older driver builds likely won't work with the current kernel.
Probably wise to see if you can get your hands on an Orange Pi R1 or Zero Plus (as of this writing) instead.
