Below diff log from OpenWRT 22.03 baseline to my changes/additions:
Added device to `02_network` script and device images creation and recipe for image creation (at the moment I'm only using `initramfs`, neither `factory` nor `sysupgrade` has been verified yet)

The initramfs kernel image works okay (sideload from console and tested uci and manual configurations for both AP and STA mode - remember these settings aren't persistent).
The file is shared here openwrt-ath79-generic-tplink_eap115-v4-initramfs-kernel.bin. Feel free to test it more and provide feedback.
My next steps are:
- Verify
factoryandsysupgradeimages format/content/size - Find way to flash
factoryimage from stock firmware - probably need to patch TP-Link'suclitedutility, however my bin differs to the one from here
