My try to bring idea of additional DT overlays from Armbian to Arch Linux. Requires bootloader ready to apply DT overlays - see this repository.
Currently only sun50i-h5-... DT overlays are supported/packaged.
User provided DT overlays are not supported.
The idea is very simple.
To enable, say additional USB port just install sun50i-h5-dto-usbport2 package (for OrangePi Zero Plus) and reboot.
If you want audio codec just install sun50i-h5-dto-analog-codec package and reboot etc.
The /boot/overlays.txt config file is updated by simple post-install hook (shell script).
See boot.txt U-Boot script.
All sun50i-h5-dto-... packages requires sunxi-dt-overlays-toolkit and sun50i-h5-dt-overlays ones.
