Both of these chips have 256kB big sectors, thus the _256K suffix, compared to their _64K counterparts, which have 64kB sectors. Also, they have four times less sectors than their _64K counterparts.

Note: Would be nice if someone actually tested this fix as I go by the datasheet and by the old code that _was_ in U-Boot before the rework.
btw. would be nice to get this one into current release to prevent it being broken. But I would _really_ appreciate some real-hardware testing here.
