In order to maximize the available space on USW-Flex boards using a
dual-image partition layout, combine the two OS partitions into a single
partition.
This allows users to access more usable space for additional packages.
Don't limit the usable image size to the size of a single OS partition.
The initial installation has to be done with an older version of OpenWrt
in case the generated image exceeds the space of a single kernel
partition in the future.

Mux the MT7530 switch's phy0/4 to the SoC's gmac1 on devices where RGMII2
pins are available. This achieves 2 Gbps total bandwidth to the CPU using
the second RGMII.
The ports called "wan" are muxed where possible. On a minority of devices,
this is not possible. Those cases:
mt7621_ampedwireless_ally-r1900k.dts: lan3
mt7621_ubnt_edgerouter-x.dts: eth0
mt7621_gnubee_gb-pc1.dts: ethblue
mt7621_linksys_re6500.dts: lan1
mt7621_netgear_wac104.dts: lan4
mt7621_tplink_eap235-wall-v1.dts: lan0
mt7621_tplink_eap615-wall-v1.dts: lan0
mt7621_ubnt_usw-flex.dts: lan1
The "wan" port is just what the vendor designated on the board/plastic
chasis of the device. On a technical level, there is no difference between
a lan and wan port on MT7621AT, MT7621DAT and MT7621ST SoCs. Prefer
connecting to WAN via the port described above for these devices to benefit
the feature brought with this patch.
mt7621_d-team_newifi-d2.dts cannot benefit this feature, although it looks
like it should, because the rgmii2 pins are wired to unused components.
Tested on a range of devices documented on the GitHub PR.

Switch port order was reversed due to reading the internal labling
(which mismatches the one on the case).

Hardware
--------
MediaTek MT7621AT
16M SPI-NOR Macronix MX25L12835FMI
Microchip PD69104B1 4-Channel PoE-PSE controller
TI TPS2373 PoE-PD controller
PoE-Controller
--------------
By default, the PoE outputs do not work with OpenWrt. To make them output
power, install the "poemgr" package from the packages feed.
This package can control the PD69104B1 PSE controller.
Installation
------------
1. Connect to the booted device at 192.168.1.20 using username/password
"ubnt" via SSH.
2. Add the uboot-envtools configuration file /etc/fw_env.config with the
following content
$ echo "/dev/mtd1 0x0 0x1000 0x10000 1" > /etc/fw_env.config
3. Update the bootloader environment.
$ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr);
fdt rm /signature; bootubnt"
$ fw_setenv bootcmd "run boot_openwrt"
4. Transfer the OpenWrt sysupgrade image to the device using SCP.
5. Check the mtd partition number for bs / kernel0 / kernel1
$ cat /proc/mtd
6. Set the bootselect flag to boot from kernel0
$ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4
7. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1
$ dd if=openwrt.bin of=/dev/mtdblock6
$ dd if=openwrt.bin of=/dev/mtdblock7
8. Reboot the device. It should boot into OpenWrt.
Restore to UniFi
----------------
To restore the vendor firmware, follow the Ubiquiti UniFi TFTP
recovery guide for access points. The process is the same for
the Flex switch.
