Why do hardware engineers keep on insisting on doing this. And why
don't software engineers when asked to review the proposed registers
push back and say No?
I know this is out of you hands, but it is something we should
encourage software engineers at SoC vendors to do. Otherwise we will
have to continually live with such a mess.
