Your bigger issue is if you can setup the DDR controller for the hole
you want.
I just remembered;;

The CCSR window always takes precedence over all local access
windows. However, the CCSR window must not overlap an LAW that
maps to the DDR controller. Otherwise, undefined behavior occurs.

So, it's not really possible to map 4GB of RAM in the lower
32-bit area, without interacting badly with the CCSR. This
means you're forced to select a 2GB LAW for DDR, then leave
2GB free, then map the rest above.. using more than 2Gb
therefore absolutely requires non-contiguous memory..?
