Sungbo Eo 1d56a7b75d ramips: mt76x8: fix bogus mediatek,portmap
mt76x8 uses esw_rt3050 driver, which does not accept mediatek,portmap with
string values. Convert the strings to integers to make it work.

According to its switch setup, WRTnode 2P/2R have a WAN port at port 0,
so the correct value should be 0x3e.

tplink_8m.dtsi uses "llllw", but it does not match switch setups of any
device using the DTSI. Remove it from the DTSI and add correct value to DTS
for each device.

These devices have a WAN port at port 0. Set the value to 0x3e.

- tplink,tl-mr3420-v5
- tplink,tl-wr840n-v4
- tplink,tl-wr841n-v13
- tplink,tl-wr842n-v5

These devices have only one ethernet port. They don't need portmap setting.

David Bauer 01dcd574a2 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.

By doing the same while performing sysupgrade, we can take advantage of
the Web-recovery in OpenWRT.

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.
