With a little work the generic plat_nand driver could probably be used
instead of this new driver or the original ts7250 driver.

The only thing special about the original ts7250 driver appears to be
the fall-back partitioning scheme that uses the size of the device to
figure out what static mtd_partition table to use.

This driver uses a similar approach but passes a callback to the
platform driver to use instead.  It also adds some conditional ecc
support.

It might be more useful to create a generic patch for plat_nand that
adds this functionality and then obsolete the old ts7250 driver.

I have been using the plat_nand driver on a custom ep93xx based board
for quite a while with no problems.
