lantiq: add Netgear DM200 support
Netgear DM200 is an inexpensive VDSL modem: CPU: VRX220 MIPS 34Kc 5.6 @ 500Mhz RAM: 64MiB Flash: 8MiB Ethernet: 1x100M DSL: VDSL2+, ADSL2+ reset button, 3x bi-color LEDs Serial port is 115200 baud, on the 4 pin header; pins from the bottom to top are GND, RX, TX. To upgrade from the vendor firmware, upload factory.img The DM200 bootloader supports flashing over TFTP; hold the reset button while powering on the device, and wait for the power light to start flashing green before releasing. The device is now listening on 192.168.0.1/24, and can be sent a factory.img or a netgear image with a TFTP put. Once the image is loaded, it will be written to the flash, and the device will reboot; this will take a few minutes. Thanks to Edward O'Callaghan and Baptiste Jonglez, who implemented their own ports for this device and provided valuable feedback. Signed-off-by: Thomas Nixon <tom@tomn.co.uk>
