When I do mtd1 + mtd2 + mtd3, I end up with 0x3d00000 instead of
0x4000000. Is that normal? Do you reserve a bit of space at the end or
is it that rcw is not starting at 0?

Did you try to create a smaller partition? Maybe we have a problem when
accessing addresses higher than X with the new driver (X to be
determined).
