Hello OpenWrt community!
How complex would it be to add support for Orange Pi 3 LTS?
The device is getting more & more popular due to affordable prices (~ $50 for a case-equipped quad-core 1.8GHz CPU, 2GB RAM, 1Gbit RJ45 port, eMMC, USB C plug, USB3.0 ports & 2.4/5GHz WiFi support)... It is superior to Raspberry Pi 3, performance-wise & price-wise.
It is definitely a best buy, especially these days when the general availability of Raspberry Pi 3 & 4 is extremely low and prices are terrible (resellers & scalpers are reselling them on eBay for $100+)...
Anyhow, the device is equipped with "Allwinner H6" SoC (Cortex A53 architecture).
I believe a support for this device wouldn't require too much effort, since it is open-source.
Also, the OpenWrt project already supports Allwinner sunxi family of SoCs - and this exact CPU architecture as well...
Feel free to hop on discussion!
