    ramips: add support for Loewe WMDR-143N
    
    The WMDR-143N is a small module originally used as a Wifi client
    in some Loewe smart TV sets. It is sold cheaply at german surplus
    shops. The module contains a RT3662 SOC.
    
    Specifications:
    
    - 500 MHz CPU Clock
    - 1x 10/100Mbps Ethernet (pin header)
    - 32 MB of RAM
    - 8 MB of FLASH
    - 2T3R 2.4/5 GHz (SOC internal)
    - 3 Antennas on PCB
    - UART pads on PCB (J3: 1 = +3.3V, 2 = RX, 3 = TX, 4 = GND), TX
      and RX are 3,3V only! The square hole is pin 1
    - Power supply pads on PCB (J6: 1 and 2 = +5V, 3 and 4 = GND)
      The square hole is pin 1
    
    The original firmware has two identical kernel/rootfs images and
    two "Factory" calibration data blocks in flash. The LEDE image
    leaves only the first "Factory" block in place and uses both
    "Kernel" blocks and the redundant "Factory" block together to gain
    enough space for the jffs2 partition.
    
    Flash instructions:
    
    You need UART and Ethernet connections to flash the board. Use
    the LEDE "sysupgrade.bin" image with tftp.
    
    Apply power to the board and in the first 5 seconds, hit 2 to
    select TFTP upload. The bootloader asks for board- and server IP
    addresses and filename.
    
    Alternate method: With the vendor firmware running, assign an IP
    address to the ethernet port, tftp the firmware image to
    /tmp and write to mtd4 ("KernelA").
