Mapping unchached memory with UDD

Hello,

I'm writing a little UDD driver to handling interrupts and shared memory
to communicate with a co-processor. Is it possible to setup and map a
"mem_region" for *uncahced* memory. Will it be automatically uncached if
it's of type UDD_MEM_PHY?

TIA,

Wolfgang.
