Hi!

Currently i'm developing a boot loader for a custom PXA255-based board.
Everything seems to work fine so far. What causes me troubles is the
access of hardware connected via CS1-4. Without MMU the HW behaves as
expected but with MMU (CS1 is mapped from 0x0400_0000 to 0x9000_0000 as
section with R/W access) the system crashes. The settings for this
mapping are the same as for memory mapped IO (not cachable, not
bufferable) which work fine. Any ideas?
