I can submit a patch that provides an alternative implementation, but 
I'm pretty sure Russell won't like it.

For reference:


Russell said that UPIO_MEM is supposed to be literally only 8-bit 
access, but then Peter Hurley posted this:


which you applied.  So my patch would remove access_32b and use 
UPIO_MEM32/UPIO_MEM instead.  It would be a little weird having both 
patches in your tree, I guess.
