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.
