I have just found that it won't be so easy as I thought because I have found
that microblaze wrong implementation was done because of others device drivers.
It means that I have to fix all device drivers to support big and
little endian accessors
first before I can switch microblaze to asm-generic/io.h. :-(
BTW: If you want to take this patch though your tree then ok, or it
can go through my
microblaze tree. Both ways should just work.
I will send the patch for uarlite when I finish my testing on
microblaze, ppc and arm.
