Yes, I plan to drop this patch.
Reason: Though this feature was introduced in linux long back, but hardly
any mtd/nand drivers using this. Also there are alternative approaches
which do not require any change in individual controller drivers, but just
in generic NAND driver.
I have proposed them in linux mtd-maillist, I'll propose same in my next
version of patch-set.
