Which ARM board are you using?

It looks like there is some issues with 16-bit register read/write. That
magic value (8a32) was written to SWSUPPORT0 with 16-bit write and then
read back as 16-bit read. For some reason, only half of the word was
read correctly.. This uses standard Linux readw() and writew(), so I
would first like to get a confirmation that those work correctly with
the used platform/kernel combination.
