Ubiquiti has a set of UniFi 802.11ax (Wi-Fi 6) AP devices. All models
include "U6" in their names and also have code names with no special
characters (including spaces).
Examples:
1. U6 Lite (codename U6-Lite)
2. U6 Long-Range (codename U6-LR)
3. U6+ (codename U6-PLUS)
4. U6 Pro (codename U6-Pro)
5. U6 Mesh (codename U6-Mesh)
6. U6 Mesh Pro (codename U6-Mesh-Pro)
7. U6 Enterprise (codename U6-Enterprise)
Use proper full names for those devices. Names in OpenWrt/DTS code may
need updating too but it can be handled later.

according to the pictures and the firmware.
But I haven't checked if the OpenWrt firmware works as well

Allow a wider audience to test this pending series.
Use about to be submitted v3 which factors out block notification support.
Apart from dropping the no longer needed (and problematic) fallback for
for the 'partitions' node being present at the device parent there are
no intended functional changes.
As opening a block device as file is not supported yet in Kernel v6.6,
use the previous method as backporting seems a bit too involving.

Prior to performing a PROGRAM LOAD RANDOM DATA operation, a WRITE
ENABLE (06h) command must be issued to change the contents of the
memory array. Following a WRITE ENABLE (06) command, **first a PROGRAM
LOAD (02h or 32h) command must be issued to reset the cache**, then
issue a PROGRAM LOAD RANDOM DATA (84h or 34h) command
This is dirty fix provided to use by MediaTek engineer Sky Huang which
may resolve the "OpenWrt Kiss of Death" issue we've been seeing on the
Linksys E8450 aka. Belkin RT3200. However, it means that everything has
to be re-written with that patch already applied, ie. we need to rebuild
the installer once it is part of snapshot builds to have any effect.
Users already on FIP-in-UBI layout are advised to re-write 'fip' UBI
volume and 'bl2' MTD partition manually once from within Linux after
this fix has been applied.
A similar fix will also be required for U-Boot.

Solder on UART:
- remove rubber ring on the bottom
- remove screws
- pull up the cylinder, maybe help by push on an ethernet socket with a screwdriver
- remove the (3) screws holding the board in the frame
- remove the board from the frame to get to the screws for the silver, flat heat shield
- remove the (3) screws holding the heat shield
- solder UART pins to the back of the board
- make sure to have the pins point out on side with the black, finned heat spread
- the markings for the pins are going to be below the silver heat shield
- Vcc is not needed
If you don't intend on using the UART outside of the installation process, you might not
want to solder:
- carefully scrape off the thin layer of epoxy on the holes (not the copper)
- place your pin header with the UART attached in the holes
- the pins, starting with the one closest to the socket:
- Vcc (not required)
- GND
- RX
- TX
- either wedge the header or hold it with your fingers so that the pins stay in contact with the board
Installation (UART):
- attach an Ethernet cable to the 1Gbps port (black) on the router
- hold the reset button while powering the router
- press CTRL-C or wait for the timeout to get to the U-Boot prompt
- prepare a TFTP server on the network to supply ..-initramfs-kernel.bin
- use 'tftpboot' in the U-Boot shell to pull the image
- boot the image using 'bootm'
- push the ..-sysupgrade to the router using your preferred method
- perform the upgrade with 'sysupgrade -n'
There is a recovery mechanism that involves fetching a file called 'recovery.bin' but that is not understood yet.
