I have a coworker working on a driver to read/write 32-bit data from/to
a 16-bit
data bus device with ARM-PXA255. He´s managed to have it working by
reading and
writing two 16-bit words (readw/writew). He´s configured the memory
control register (MSCx) for 16-bit data bus (CS5). Although it works,
we'd like to know if it is possible to use 32-bit instructions
(readl/writel) and let the pxa manage the 32 bit words
concatenation/splitting just like x86s (386SX for instance) do in
similar situations. We´re using non-burst accesses.
Any ideas/suggestions are very welcome.

TIA

Elder.
