Just curious, Would someone add openwrt support for the Edgerouter 12 since the Edgerouter 4 has been supported for a while? It has the same CPU processor but an added switch. I just got hold of the edgerouter 12 from a client who had it in service for the last 4 years. I'm willing to do any tested if someone points me in that direction...
That model appears to have more in common with the Edgerouter 6 than the 4, with its Marvell CN7130 SoC, so that would be a good place to start.
