problem overwriting all-0xff data in NAND [2]
=============================================

Although it occured only when writing JFFS2 images so far, this is a generic
issue and needs to be fixed, right?

As explained in the thread linked above, this issue should be fixed in your
flashing tool, _not_ in your driver. The nand device you are using does not
support programming pages multiple times in a row; pretending it does in the
special all-0xff case is inefficient (you need to detect all-0xff data) and
unnecessary (just do not program blank pages !).
