Right!
writew() - assumes that you are talking to a peripheral and all peripherals
must be little endian , thank you PCI.

__raw_writew() - accesses the memory in the native format which is
big-endian in your case.


To answer your other question:
You can not set an attribute on a memory region within the memory controller
to force the hardware to handle this for you on a region by region basis.
The chip's endianness may be configurable. This is an exercise let to the
programmer.  :(
