ramips: add support for ALFA Network Tube-E4G
ALFA Network Tube-E4G is an outdoor, dual-SIM LTE Cat. 4 CPE, based on MediaTek MT7620A, equipped with Quectel EC25 miniPCIe modem. Specification: - MT7620A (580 MHz) - 64/128/256 MB of RAM (DDR2) - 16/32 MB of flash (SPI NOR) - 1x 10/100 Mbps Ethernet, with passive PoE support (24 V) - 1x miniPCIe slot (with PCIe and USB 2.0 buses) - 2x SIM slot (mini, micro) with detect and switch driven by GPIO - 1x detachable antenna (modem main) - 1x internal antenna (modem div) - 1x GPS passive antenna (optional) - 5x LED (all driven by GPIO) - 1x button (reset) - UART (4-pin, 2.54 mm pitch) header on PCB Other: Default SIM slot is selected at an early stage by U-Boot, based on 'default_sim' environment value: 1 or unset = SIM1 (mini), 2 = SIM2 (micro). U-Boot also resets the modem, using #PERST signal, before starting kernel. Flash instruction: You can use the 'sysupgrade' image directly in vendor firmware which is based on OpenWrt (make sure to not preserve settings - use 'sysupgrade -n -F ...' command). Alternatively, use web recovery mode in U-Boot: 1. Power the device with reset button pressed, the LAN LED will start blinking slowly and after ~3 seconds, when it starts blinking faster, you can release the button. 2. Setup static IP 192.168.1.2/24 on your PC. 3. Go to 192.168.1.1 in browser and upload 'sysupgrade' image. Signed-off-by: Piotr Dymacz <pepe2k@gmail.com>v19.07.3_mercusys_ac12_duma
