ramips: Add support for ZBT WE1026-5G The ZBT WE1026-5G (http://www.zbtlink.com/products/router/WE1026-5G.html) is the follow-up to the ZBT WE1026 and is based on MT7620. For the previous WE1026, the ZBT WE826 image could be used. However, as the name implies, the -5G comes equipped with a 5GHz wifi radio. As the WE826 only has a 2.4GHz radio, the addition of 5GHz means that a separate image is needed for the WE1026-5G. I suspect that this image will also work on the previous WE1026, but I don't have a device to test with. The WE1026-5G has following specifications: * CPU: MT7620A * 1x 10/100Mbps Ethernet. * 16 MB Flash. * 64 MB RAM. * 1x USB 2.0 port. * 1x mini-PCIe slots. * 1x SIM slots. * 1x 2.4Ghz WIFI. * 1x 5GHz wifi (MT7612) * 1x button. * 3x controllable LEDs. Works: * Wifi. * Switch. * mini-PCIe slot. Only tested with a USB device (a modem). * SIM slot. * Sysupgrade. * Button (reset). Not working: * The 5GHz WIFI LED is completely dead. I suspect the issue is the same as on other devices with Mediatek 5Ghz wifi-cards/chips. The LED is controlled by the driver, and mt76 (currently) does not support this. Not tested: * SD card reader. Notes: * The modem (labeled 3G/4G) and power LEDs are controlled by the hardware. * There is a 32MB version of this device available, but I do not have access to it. I have therefor only added support for the 16MB version, but added all the required infrastructure to make adding support for the 32MB version easy. Installation: The router comes pre-installed with OpenWRT, including a variant of Luci. The initial firmware install can be done through this UI, following normal procedure. I.e., access the UI and update the firmware using the sysupgrade-image. Remember to select that you do not want to keep existing settings. Recovery: If you brick the device, the WE1026-5G supports recovery using HTTP. Keep the reset button pressed for ~5sec when booting to start the web server. Set the address of the network interface on your machine to 192.168.1.2/24, and point your browser to 192.168.1.1 to access the recovery UI. From the recovery UI you can upload a firmware image.
