I think Pine64 is another one to look at for software support. It's not immediate as they don't design the chips, but they do work on mainline Linux support for their products. The PinePhone Pro and Pinebook Pro both using the RK3399 SoC is pretty well supported by mainline now, so you can run mainline Linux the not-Raspberry Pi boards with RK3399s (Orange Pi 4, Rock Pi 4). Armbian probably the one to provide updated installs. Pine64's newer QuartzPro64 board uses an RK3588, so I hope to see good mainline support there too as the Orange Pi 5 and Rock 5 (no longer a Pi) use the same SoC. https://wiki.pine64.org/wiki/QuartzPro64_Development#Upstreaming_Status https://wiki.pine64.org/wiki/QuartzPro64_Development#Upstrea...
