ath79/nand: add support for Netgear WNDR4300SW This patch adds support for the WNDR4300SW, marketed by California ISP SureWest (hence the 'SW' suffix). Hardware wise, it's identical to the WNDR4300 v1. Specifications: * SoC: Atheros AR9344 * RAM: 128 MB * Flash: 128 MB NAND flash * WiFi: Atheros AR9580 (5 GHz) and AR9344 (2,4 GHz) * Ethernet: 5x 1000Base-T * LED: Power, WAN, LAN, WiFi, USB, WPS * UART: on board, to the right of the RF shield at the top of the board Installation: * Flashing through the OEM web interface: + Connect your computer to the router with an ethernet cable and browse to http://192.168.1.1/ + Log in with the default credentials are admin:password + Browse to Advanced > Administration > Firmware Upgrade in the Netgear interface + Upload the Openwrt firmware: openwrt-ath79-nand-netgear_wndr4300sw-squashfs-factory.img + Proceed with the firmware installation and give the device a few minutes to finish and reboot. * Flashing through TFTP: + Configure your wired client with a static IP in the 192.168.1.x range, e.g. 192.168.1.10 and netmask 255.255.255.0. + Power off the router. + Press and hold the RESET button (the factory reset button on the bottom of the device, with the red circle around it) and turn the router on while keeping the button pressed. + The power LED will start flashing orange. You can release the button once it switches to flashing green. + Transfer the image over TFTP: $ tftp 192.168.1.1 -m binary -c put openwrt-ath79-nand-netgear_wndr4300sw-squashfs-factory.img
