this would require binary Sophgo RiscV toolchain, which was the whole
point of my ARM64 BSP. So, while I could add RiscV counterparts, they
would be completely untested.

On the macro level that how I see the current state of upstream affairs:

RiscV:
There are necessary upstream packages available required to boot, but
there is no upstream toolchain to build them.

ARM64:
There is an upstream toolchain, but the published U-Boot is being
linked with ATF binaries -- I was planning to come up with pure
U-Boot BSP for this, without binary blobs.
