+Subject: ramips: add support for Archer C50 v4
+
+This adds support for the TP-Link Archer C50 v4.
+It uses the same hardware as the v3 variant, sharing the same FCC-ID.
+
+CPU: MediaTek MT7628 (580MHz)
+RAM: 64M DDR2
+FLASH: 8M SPI
+WiFi: 2.4GHz 2x2 MT7628 b/g/n integrated
+WiFI: 5GHz 2x2 MT7612 a/n/ac
+ETH: 1x WAN 4x LAN
+LED: Power, WiFi2, WiFi5, LAN, WAN, WPS
+BTN: WPS/WiFi, RESET
+UART: Near ETH ports, 115200 8n1, TP-Link pinout
+
+Create Factory image
+--------------------
+As all installation methods require a U-Boot to be integrated into the
+Image (and we do not ship one with the image) we are not able to create
+an image in the OpenWRT build-process.
+
+Download a TP-Link image from their Wesite and a OpenWRT sysupgrade
+image for the device and build yourself a factory image like following:
+
+TP-Link image: tpl.bin
+OpenWRT sysupgrade image: owrt.bin
+
+ > dd if=tpl.bin of=boot.bin bs=131584 count=1
+ > cat owrt.bin >> boot.bin
+
+Installing via Web-UI
+---------------------
+Upload the boot.bin via TP-Links firmware upgrade tool in the
+web-interface.
+
+Installing via Recovery
+-----------------------
+Activate Web-Recovery by beginning the upgrade Process with a
+Firmware-Image from TP-Link. After starting the Firmware Upgrade,
+wait ~3 seconds (When update status is switching to 0%), then
+disconnect the power supply from the device. Upgrade flag (which
+activates Web-Recovery) is written before the OS-image is touched and
+removed after write is succesfull, so this procedure should be safe.
+
+Plug the power back in. It will come up in Recovery-Mode on 192.168.0.1.
+When active, all LEDs but the WPS LED are off.
+Remeber to assign yourself a static IP-address as DHCP is not active in
+this mode.
+
+The boot.bin can now be uploaded and flashed using the web-recovery.
+
+Installing via TFTP
+-------------------
+Prepare an image like following (Filenames from factory image steps
+apply here)
+
+ > dd if=/dev/zero of=tp_recovery.bin bs=196608 count=1
+ > dd if=tpl.bin of=tmp.bin bs=131584 count=1
+ > dd if=tmp.bin of=boot.bin bs=512 skip=1
+ > cat boot.bin >> tp_recovery.bin
+ > cat owrt.bin >> tp_recovery.bin
+
+Place tp_recovery.bin in root directory of TFTP server and listen on
+192.168.0.66/24.
+
+Connect router LAN ports with your computer and power up the router
+while pressing the reset button. The router will download the image via
+tftp and after ~1 Minute reboot into OpenWRT.
+
+U-Boot CLI
+----------
+U-Boot CLI can be activated by holding down '4' on bootup.
+
+Dual U-Boot
+-----------
+This is the first TP-Link MediaTek device to feature a split-uboot
+design. The first (factory-uboot) provides recovery via TFTP and HTTP,
+jumping straight into the second (firmware-uboot) if no recovery needs
+to be performed. The firmware-uboot unpacks and executed the kernel.
+
+Web-Recovery
+------------
+TP-Link integrated a new Web-Recovery like the one on the Archer C7v4 /
+TL-WR1043v5. Stock-firmware sets a flag in the "romfile" partition
+before beginning to write and removes it afterwards. If the router boots
+with this flag set, bootloader will automatically start Web-recovery and
+listens on 192.168.0.1. This way, the vendor-firmware or an OpenWRT
+factory image can be written.
+
+It is important to note that Web-Recovery is only based on this flag. It
+can't detect e.g. a crashing kernel or other means. Once activated it
+won't boot the OS before a recovery action (either via TFTP or HTTP) is
+performed. This recovery-mode is indicated by an illuminated WPS-LED on
+boot.
