Does anybody know why it isn't built for 6xx cores?

Because 6xx cores are cache coherent and there shouldn't
be any need for "uncached" memory regions.

I'm working on the ATM driver and it seems that certain external memory
areas accessed by the PQII CPM by-pass the cache.

That's news to me, and I've written lots of CPM drivers, including ATM.
Do you have a specific example?

Thanks.
