OK, but as you know, not the tradiaional way of booting most other linux
systems.  ;)

I'm working on getting RISC-V supported in kernelCI in a fully-automated
way, and I don't currently have the time to add add support for BBL+FSBL
to kernelCI automation tooling, so having u-boot support is the best way
to get support in kernelCI, IMO.
