Specifications:

- MT7628NN @ 580 MHz
- 32 MB RAM
- 8 MB Flash
- 5x 10/100 Mbps Ethernet (built-in switch)
- 2.4 GHz WLAN
- 2x external, non-detachable antennas (1x for RT-N10P V3)

Flash instructions:

2. Connect PC to the router via LAN.
3. Turn router off, press and hold reset button, then turn it on.
4. Keep the button pressed till power led starts to blink.
5. Upload the firmware file via TFTP. (Any filename is accepted.)
6. Wait until the router reboots.

v2: RT-N12 VP *B1* was incorrectly mentioned as *B3* in mt76x8.mk
v3: switch to master branch & split device group into individual entries
v4: add licenses, update DTS(I), move `leds` section to DTS'es, s/_/-/ in boardnames
