   For RAM, 'size' must be a multiple of the target page size.

   If (phys_offset & ~TARGET_PAGE_MASK) != 0, then it is an

   io memory page.  The address used when calling the IO function is

   the offset from the start of the region, plus region_offset.  Both

   start_addr and region_offset are rounded down to a page boundary
