* ramips: add support for ipTIME A104nsSungbo Eo2019-12-171-0/+59
ipTIME A104ns is a 2.4/5GHz band AC750 router, based on MediaTek MT7620A. Specifications: - SoC: MT7620A - RAM: DDR2 64MB - Flash: SPI NOR 8MB - WiFi: - 2.4GHz: SoC internal - 5GHz: MT7610EN - Ethernet: 5x 10/100Mbps - Switch: SoC internal - USB: 1x 2.0 - UART: - J2: 3.3V, TX, RX, GND (3.3V is the square pad) / 57600 8N1 Installation via web interface: 1. Flash **initramfs** image through the stock web interface. 2. Boot into OpenWrt and perform sysupgrade with sysupgrade image. Revert to stock firmware: 1. Perform sysupgrade with stock image. In contrast to to-be-supported A1004ns, the A104ns has no usable value in 0x1fc40 (uboot), so wan_mac needs to be calculated. Also note that GPIOs for the LEDs really are inverted compared to the A1004ns.
