[LEDE-DEV] [PATCH] ramips: add support for Loewe WMDR-143N

[Mathias Kresin]

> 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").

I added a fix for the pinmux related hang you reported to my staging 
tree[0]. I've merge your patch with the removed pinmux on top.

Would you please build an image for the Loewe WMDR-143N from my staging 
tree and report back whether the issue is fixed!
