275a76e59a ramips: disable unsupported background-radar
The UniFi 6 Lite as well as the Tenbay T-MB5EU do not have the third
background-radar chain. For the Tenbay, the connector is present,
however no antenna is connected to it.

ef5f3eb700 ramips: read Tenbay T-MB5EU address from single location
Currently the WAN MAC address is read from a different offset contrary
to all other addresses.

There's conflicting information whether offset 0x28 on the factory
partition contains the valid WAN mac for all devices while 0x4 seems to
be uniform.

Read the WAN mac from this location and calculate it.

51b61fd570 ramips: add support for Tenbay T-MB5EU-V01
Hardware
--------
MediaTek MT7621 SoC
256M DDR3
16MB BoHong SPI-NOR
MediaTek MT7905+7975 2x2T2R DBDC bgnax / acax
RGB LED
WPS + RESET Button
UART on compute module (silkscreened / 115200n8)

The router itself is just a board with Power / USB / RJ-45 connectors
and DC/DC converters. The SoC and WiFi components are on a
daughterboard which connect using two M.2 connectors.

The compute module has the model number "T-CB1800K-DM2 V02" printed on
it. The main baord has "T-MB5EU V01" printed on it. This information
might be useful, as it's highly likely either of these two will be
reused in similar designs.

The router itself is sold as Tenbay T-MB5EU directly from the OEM as
well as "KuWFI AX1800 Smart WiFi 6 Eouter" on Amazon.de for ~50€ in a
slightly different case.

Installation
------------

A Tool for creating a factory image for the Vendor Web Interface can be
found here: https://github.com/blocktrron/t-mb5eu-v01-factory-creator/

As the OEM Firmware is just a modified LEDE 17.01, you can also access
failsafe mode via UART while the OS boots, by connecting to UART
and pressing "f" when prompted. The Router is reachable at
192.168.1.1 via root without password.

Transfer the OpenWrt sysupgrade image via scp and apply with sysupgrade
using the -n and -F flags.

Alternatively, the board can be flashed by attaching to the UART
console, interrupting the boot process by keeping "0" pressed while
attaching power.

Serve the OpenWrt initramfs using a TFTP server with address
192.168.1.66. Rename the initramfs to ax1800.bin.

Attach your TFTP server to one of the LAN ports. Execute the following
commands.

 $ setenv ipaddr 192.168.1.67
 $ setenv serverip 192.168.1.66
 $ tftpboot 0x84000000 ax1800.bin
 $ bootm

Wait for the device to boot. Then transfer the OpenWrt sysupgrade image
to the device using SCP and apply sysupgrade.
