ramips: mt7621: add support for Gemtek WVRTM-127ACN and WVRTM-130ACN The Gemtek WVRTM-127ACN is an indoor dual band wifi router with internal antennas and 3 Gigabit Ethernet ports. The Gemtek WVRTM-130ACN is an indoor dual band wifi router with external antennas and 5 Gigabit Ethernet ports. Hardware of WVRTM-127ACN: - SoC: Mediatek MT7621AT (880 MHz, dual core) - RAM: 128 MB - Storage: 128 MB NAND SLC flash - Ethernet: 3x 10/100/1000 Mbps LAN1,LAN2 & WAN - Wireless: 2.4GHz: Mediatek MT7603EN (802.11b/g/n) - Wireless: 5GHz: Mediatek MT7612EN (802.11n/ac) - LEDs: 11x - Buttons: 2x WPS, reset - USB: 1x 3.0 - Power: 56 VDC, 0.54 A, PoE+ IN (WAN) - PoE: 1x PoE+ 802.3af/at (WAN) - Uart: GND RX TX VCC - J2 (GND near WAN) - Board silkscreen: "WVRTM-127ACN_V02" "19K-513-8500R" "RoHS" "1717" Hardware of WVRTM-130ACN: - SoC: Mediatek MT7621AT (880 MHz, dual core) - RAM: 128 MB (Kioxia TC58BVG0S3HTA00) - Storage: 128 MB NAND SLC (Winbond W971GG6SB-25) - Ethernet: 5x 10/100/1000 Mbps LAN1,LAN2,LAN3,LAN4 & WAN - Wireless: 2.4GHz and 5GHz Mediatek MT7615DN (802.11ac/b/g/n) (DBDC) - LEDs: 10x - Buttons: 3x Power, WPS, reset - USB: 1x 3.0 - Power: 56 VDC, 0.54 A, PoE+ (WAN) - PoE: 1x PoE+ 802.3af/at (WAN) - Uart: GND RX TX VCC - J2 (GND near WAN) - Board silkscreen: "WVRTM-130ACN_V01" "19K-515-4500R" "RoHS" "2112" Enable access to uboot menu (needed in wvrtm-130acn): - The access to uboot menu is blocked by `bootdelay = 0` set in ubootenv.
