While I think that consolidating PERST# handling is a great idea, I already
have 3-4 things with higher priority on my TODO list (and some things have
been there for quite a while).

So unless something has rather high priority, I currently don't know when
I will have some spare cycles.

I really hope that someone will have some spare cycles to work on this,
because the PERST# handling in the controller drivers really is a mess.


Kind regards,
Niklas
