NAME
       nand_lock - [REPLACEABLE] locks all blocks present in the device

SYNOPSIS
       int nand_lock(struct mtd_info * mtd, loff_t ofs, uint64_t len);

ARGUMENTS
       mtd
           mtd info

       ofs
           offset to start unlock from

       len
           length to unlock

DESCRIPTION
       This feature is not supported in many NAND parts. 'Micron' NAND parts do have this
       feature, but it allows only to lock all blocks, not for specified range for block.
       Implementing 'lock' feature by making use of 'unlock', for now.

       Returns lock status.
