Theoretically since sm8150 we should be using a single CTL for the

Hmm.. so is it a software construct? E.g. "pass half of the data to
each of the INTFs and tell them to cooperate"?
It is not a fully software construct, if I understand correctly. You
have to program either a single CTL or two CTLs for a flush.
Apart from that, since it's temporary, I think it deserves a comment
reminding us to fix it eventually™
Sure, this is, I think, a next item on my plate after getting all of
wide planes and catalog in: to rework CTL support for sm8150+.
