ramips: Add support for Dual-Q H721 Dual-Q H721 is a router platform board, it is the smaller model of the U7621-06. The device has the following specifications: MT7621AT (880 MHz) 256 of RAM (DDR3) 16 MB of FLASH (MX25l12805d SPI) 5x 1 Gbps Ethernet (MT7621 built-in switch) 1x M.2 (NGFF) 3.7V 3A max for 5G M.2 Modem work at USB3.0 mode 1x Minipcie 3.7V 3A max for LTE Modem work at USB2.0 Mode 2x Minipcie for WIFI card 4x Lan+1x Wan 10/100M/1000M RJ45 port 14x LEDs (1x GPIO-controlled) 1x reset button 1x UART header (4-pins) 1x mico SD-card reader 1x DC jack for main power (5~27 V) The following has been tested and is working: Ethernet switch miniPCIe slots (tested with Wi-Fi cards and LTE modem cards) miniSIM slot (works with normal size simcard) sysupgrade reset button micro SD-card reader Installation: This board has no locked down bootloader. The seller can be asked to install openwrt, so upgrades are standard sysupgrade method. Recovery: This board contains a Chinese, closed-source bootloader called Breed (Boot and Recovery Environment for Embedded Devices). Breed supports web recovery and to enter it, you keep the reset button pressed for around 5 seconds during boot. Your machine will be assigned an IP through DHCP and the router will use IP address 192.168.1.1. The recovery website is in Chinese, but is easy to use. Click on the second item in the list to access the recovery page, then the second item on the next page is where you select the firmware. In order to start the recovery, you click the button at the bottom.
