ath79: Add support for Buffalo WZR-HP-G300NH This device is a wireless router working on 2.4GHz band based on Qualcom/Atheros AR9132 rev 2 SoC and is accompanied by Atheros AR9103 wireless chip and Realtek RTL8366RB/S switches. Due to two different switches being used also two different devices are provided. Specification: - 400 MHz CPU - 64 MB of RAM - 32 MB of FLASH (NOR) - 3x3:2 2.4 GHz 802.11bgn - 5x 10/100/1000 Mbps Ethernet - 4x LED, 3x button, On/Off slider, Auto/On/Off slider - 1x USB 2.0 - bare UART header place on PCB Flash instruction: - NOTE: Pay attention to the switch variant and choose the image to flash accordingly. (dmesg / kernel logs can tell it) - Methods for flashing - Apply factory image in OEM firmware web-gui. - Sysupgrade on top of existing OpenWRT image - U-Boot TFPT recovery for both stock or OpenWRT images: The device U-boot contains a TFTP server that by default has an address 192.168.11.1 (MAC 02:AA:BB:CC:DD:1A). During the boot there is a time window, during which the device allows an image to be uploaded from a client with address 192.168.11.2. The image will be written on flash automatically. 1) Have a computer with static IP address 192.168.11.2 and the router device switched off. 2) Connect the LAN port next to the WAN port in the device and the computer using a network switch. 3) Assign IP 192.168.11.1 the MAC address 02:AA:BB:CC:DD:1A arp -s 192.168.11.1 02:AA:BB:CC:DD:1A 4) Initiate an upload using TFTP image variant curl -T <imagename> tftp://192.168.11.1 5) Switch on the device. The image will be uploaded subsequently. You can keep an eye on the diag light on the device, it should keep on blinking for a while indicating the writing of the image. General notes: - In the stock firmware the MAC address is the same among all interfaces so it is left here that way too. Recovery: - TFTP method - U-boot serial console Differences to ar71xx platform - This device is split in two different targets now due to hardware being a bit different under the hood. Dynamic solution within the same image is left for later time. - GPIOs for a sliding On/Off switch, marked 'Movie engine' on the device cover, were the wrong way around and were renamed qos_on -> movie_off, qos_off -> movie_on. Associated key codes remained the same they were. The device tree source code is mostly based on musashino's work Signed-off-by: Mauri Sandberg <sandberg@mailfence.com> 2020-09-07 19:04:26 +00:00			`// SPDX-License-Identifier: GPL-2.0-or-later OR MIT`
