Probably the best thing would be to arrange the memory map such that these
two banks end up contiguous [in logical memory] using the MMU. Note that
the SA11x0 variant already moves the FLASH around, so this will not be a
big deal. Once this is in place, some simple additions to the StrataFlash
driver will handle it for you.
