[RFC]mtd-util flash_unlock support on NAND

[Subramani Venkatesh]

Hi,
I am Currently working on yaffs2 and ubifs file system testing on
omap, during which I could not do flash_unlock on NAND using mtd
utility to perform flash_eraseall.
Reading mtd nand driver shows that mtd->unlock is intialized to NULL
in nand_base.c file, is their any particular reason why there is no
nand_unlock callback function implemented?
Is their any chance to implement it in the main code base line?
