I'd also be interested in any work done to enable non-contiguous

you can set up LAWs for it?
One thing I wanted to try was installing 4GB in a system and
"overlapping" IO (since there is very little of it on a stock
MPC8641DHPCN) in the top ~256MB-512MB, but I am fairly sure this is
NOT supported because of the way the LAWs work, and also the alignment
of the LAWs means it is not fine enough granularity to map between 2GB
and 4GB into a window (you can have 2GB or 4GB but not some more
arbitrary value?)
On my point of view, LAWs sizes are power of 2 and should be aligned to
the window size. But there is 10 LAWs you can combine to achieve quite a
lot of different mappings.
