Depending on the flash chips you're using, maybe. Sometimes you need to
access the chip with the correct address.

The MTD partitioning code is (currently) just a set of wrappers round the
real MTD functions, which add an offset and call the real chip driver's
methods. It's fairly simple to do your own such wrapper rather than using
the ones in mtdpart.c.
