Supporting EAP225 v5

Hi,
is it possible to run OpenWrt on an EAP225 v5?
Seems to be MT7629 with 16MB flash and 128MB RAM.

Some output from the UART interface:

F0: 102B 0000

F1: 0000 0000

V0: 0000 0000 [0001]

00: 0000 0000

BP: 0000 0041 [0000]

G0: 0190 0000

T0: 0000 0203 [000F]

FCC: https://fcc.report/FCC-ID/2AXJ4EAP225V5

So they switched to Mediatek for the EAP225 too now. Maybe have a look at the EAP615-Wall port, could very well be that TP-Link uses a similar configuration here for the FIT images.

The board appears to have MT7761N and MT7762N as radios, which is the first time I've seen these used in the EAP series. Curiously enough, these are 3×3 radios, and there are three antennas in the FCC photos. Only two of the three are labelled with "5G" however, and the antenna test report only lists two for the 5GHz range too.
