ramips: add support for D-Link DAP-1325-A1
This patch adds support for D-Link DAP-1325-A1 (Range Extender Wi-Fi N300) Specifications: - SoC: 580Mhz MT7628NN - RAM: 64MB, DDR2 SDRAM - Storage: 8MB, SPI (W25Q64JVSSIQ) - Ethernet: 1x 10/100 LAN port - WIFI: 2.4 GHz 802.11bgn - LED: Status (2x to provide 3 colors), Wi-Fi Signal Strength (4x) - Buttons: Reset, WPS - UART: Serial console (57600, 8n1) Row of 4 holes near LAN port, starting from square hole: 3.3V, TX,RX,GND - FCC ID: fccid.io/KA2AP1325A1/ Installation: Failsafe UI Firmware can be uploaded with Failsafe UI web page: - turn device off - press and hold reset button - turn device on - keep holding reset until red wifi strength led turns on (ab. 10sec) - connect to device through LAN port PC must be configured with static ip (192.168.0.x) - connect to 192.168.0.50 - select image to be flashed and upload. Device will reboot after successful update Serial port/TFTP server - Connect through serial connectors on PCB (e.g. with teraterm) - Set up a TFTP server, and connect through LAN with static IP - Put image file in the root of the server - Boot the device and select '2' at U-Boot startup - Set device IP, server IP and image file name - Start upload and flash Signed-off-by: Giovanni Cascione <ing.cascione@gmail.com> [fix whitespaces in DTS, convert to nvmem, add mtd-eeprom] Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
