  so you have working BSPs for both of those? very cool. warning that
i know effectively nothing about RISC-V but this is apparently my
weekend project to dig into it. i don't see a meta-riscv-specific
mailing list, so i assume if i want to start sending simple patches
for meta-riscv, they would go here?

  already built and tested qemuriscv64, so i guess i'll work backwards
from there and examine the configuration and construction of the
components. opensbi, here we come ...
