Hi!
Official OpenWrt support was introduced by commit:
committed 12:15PM - 03 Sep 20 UTC
The HooToo HT-TM05 is a battery powered router, with an Ethernet and USB port.
V… endor U-Boot limited to 1.5 MB kernel size, so use lzma loader (loader-okli).
Specifications:
SOC: MediaTek MT7620N
BATTERY: 10400mAh
WLAN: 802.11bgn
LAN: 1x 10/100 Mbps Ethernet
USB: 1x USB 2.0 (Type-A)
RAM: 64 MB
FLASH: GigaDevice GD25Q64, Serial 8 MB Flash, clocked at 50 MHz
Flash itself specified to 80 MHz, but speed limited by mt7620 SPI
fast-read enabled (m25p)
LED: Status LED (blue after boot, green with WiFi traffic
4 leds to indicate power level of the battery (unable to control)
INPUT: Power, reset button
MAC assignment based on vendor firmware:
2.4 GHz *:b4 (factory 0x04)
LAN/label *:b4 (factory 0x28)
WAN *:b5 (factory 0x2e)
Tested and working:
- Ethernet
- 2.4 GHz WiFi (Correct MAC-address)
- Installation from TFTP (recovery)
- OpenWRT sysupgrade (Preserving and non-preserving), through the usual
ways: command line and LuCI
- LEDs (except as noted above)
- Button (reset)
- I2C, which is needed for reading battery charge status and level
- U-Boot environment / variables (from U-Boot, and OpenWrt)
Installation:
- Download the needed OpenWrt install files, place them in the root
of a clean TFTP server running on your computer. Rename the files as,
- ramips-mt7620-hootoo_tm05-squashfs-kernel.bin => kernel
- ramips-mt7620-hootoo_tm05-squashfs-rootfs.bin => rootfs
- Plug the router into your computer via Ethernet
- Set your computer to use 10.10.10.254 as its IP address
- With your router shut down, hold down the power button until the first
white LED lights up.
- Push and hold the reset button and release the power button. Continue
holding the reset button for 30 seconds or until it begins searching
for files on your TFTP server, whichever comes first.
- The router (10.10.10.128) will look for your computer at 10.10.10.254
and install the two files. Once it has finished installation, it will
automatically reboot and start up OpenWrt.
- Set your computer to use DHCP for its IP address
Notes:
- U-Boot environment can be modified, u-boot-env is preserved on initial
install or sysupgrade
- mtd-concat functionality is included, to leave a "hole" for u-boot-env,
combining the OEM kernel and rootfs partitions
I would like to thank @mpratt14 and @xabolcs for their help getting the
lzma loader to work!

and it's first included in OpenWrt 21.02.
This device has a clone which was somewhat supported before: RAVPower RP-WD03.
The initial support of RP-WD03 wasn't as good as it could be and was cleaned up later by @adrianschmutzler and @arrmo .
Read the patch series for the details, which ending here:
committed 11:25PM - 11 Sep 20 UTC
HooToo HT-TM05 and RAVPower RP-WD03 have almost identical hardware
(except for R… AM size) and are from the same vendor (SunValley).
Create a common DTSI file for them.

You will find the commit: "ramips: fix partitions and boot for RAVPower RP-WD03", and there will be the reason:
The RAVPower RP-WD03 is a battery powered router, with an Ethernet and
USB port. Due due a limitation in the vendor supplied U-Boot bootloader,
we cannot exceed a 1.5 MB kernel size, as is the case with recent builds
(i.e. post v19.07). This breaks both factory and sysupgrade images.

The RAVPower RP-WD03 is a battery powered router, with an Ethernet and
USB port.… Due due a limitation in the vendor supplied U-Boot bootloader,
we cannot exceed a 1.5 MB kernel size, as is the case with recent builds
(i.e. post v19.07). This breaks both factory and sysupgrade images.
To address this, use the lzma loader (loader-okli) to work around this
limitation.
The improvements here also address the "misplaced" U-Boot environment
partition, which is located between the kernel and rootfs in the stock
image / implementation. This is addressed by making use of mtd-concat,
maximizing space available in the booted image.
This will make sysupgrade from earlier versions impossible.
Changes are based on the recently supported HooToo HT-TM05, as the
hardware is almost identical (except for RAM size) and is from the same
vendor (SunValley). While at it, also change the SPI frequency
accordingly.

- Download the needed OpenWrt install files, place them in the root

Most of the changes in this commit are the work of Russell Morris (as
credited below), I only wrapped them up and added compat-version.
Thanks to @mpratt14 and @xabolcs for their help getting the lzma loader
to work!

And if you search for that RP-WD03 device, you could find lot of posts about the same: OpenWrt doesn't start after upgrade. E.g.:
Hi,
I tried to flash openwrt master on a ravpower wd03 and the device did not start anymore.
v18.06.4 works fine.
Using a serial console I see the following happening:
U-Boot 1.1.3 (May 7 2014 - 05:33:12)
Board: Ralink APSoC DRAM: 32 MB
relocate_code Pointer at: 81fac000
enable ephy clock...done. rf reg 29 = 5
SSC disabled.
spi_wait_nsec: 29
spi device id: c8 40 17 c8 40 (4017c840)
Warning: un-recognized chip ID, please update bootloader!
raspi_read: from:1d4000 len:1000
*** Warning - …
Just use the "kernel (squasfs)" as kernel
and "rootfs" for rootfs
files with TFTP recovery from firmware selector and you are good!
