RISC-V works exactly the same as ARM from the perspective of pine64 and distribution and it will not solve anything

The currently shipping affordable RISC-V SBCs tend to be RISC-V cores embedded with a bunch of frustrating undocumented peripherals, more or less the same as with affordable ARM SBCs. It's disappointing :(

See for instance the Allwinner D1 chip.

There are standards for ARM bootloaders to have UEFI compat. Pine64 just needs to care.
