I only updated the sk boards as these are the only ones that have IO+DDR
support that I know works and need the new memory region layout. But
thinking about this, updating the memory region structure shouldn't be a
problem for the other boards either, of course I can't tell if IO+DDR
would work on them, but the new memory region layout shouldn't break
anything.

I can respin the series or do a followup series with modifications for
all boards if you like.

Best
Markus
