Okay, thanks for explaining. A0 is the silicon revision, and it is
currently the only version that exists. I was just trying to be as
specific as possible. I'm okay with dropping '-a0'.

Should I change the plic compatible to 'tenstorrent,blackhole-plic' too?

I see you gave a Rb for riscv/tenstorrent.yaml but that does have
'tenstorrent,blackhole-a0-card' and 'tenstorrent,blackhole-a0'. Should I
drop '-a0' from those too or leave as-is?

Thanks,
Drew
