ar71xx: Add support for Teltonika RUT900
Teltonika RUT900 is a Router with LTE dual SIM, WiFi, 4x Ethernet ports, I/O, RS232, RS485, GPS. The device ist based on a Atheros AR9344 rev 3, Specifications: - 560/450/225 MHz (CPU/DDR/AHB) - 128 MB of RAM - 16 MB of FLASH - Serial Console header on a Card Board edge connector - 4x 10/100 Mbps Ethernet (3x LAN, 1x WAN) - 2.4 GHz Wifi - 2x external, detachable Wifi antennas - LTE Modem Huawei ME909u-521 (Also other Modem seen) - 2x LTE antennas - 1x GPS antenna - 7x LED, 1x button - 1x USB Connector - 1x Serial RS232 - 1x Serial RS485 - 1x MicroSD Card The GPL sources of the device are available at www.teltonika.lt/gpl/ and are based on OpenWRT Barrier Breaker (14.07) Running from tftp: The Router starts into the uboot Webupdater if the Button ist pressed more than 3 seconds, if no Network cable is attached it starts the uboot serial console, from there the router loads the firmware image via tftpboot from 192.168.1.2:firmware.bin (the router has the 192.168.1.1). With bootm the loaded image will be booted. Signed-off-by: Steffen Weinreich <steve@weinreich.org>
