It's not about the arm as an instruction set (I'm writing this from the arm machine running linux). It's the drivers, bootloader, all the fdt glue. You don't just need support for arm, but for the specific board on the specific SOC. Want a different board on a soc that already works? Welcome to the world of writing this kind of things: https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/rockchip/rk3588-orangepi-5.dtsi https://github.com/torvalds/linux/blob/master/arch/arm64/boo... and compiling the kernel from some dude's branch instead of going with mainline. I have the risc thing too, that magically works on mainline kernel somehow, but is slow.
