Browse Source 
Since the using of Bad Block Table is not constantly a good behave
I had made it configurable.

Include support for MX31PDK (3DS) platform. This includes specific
configurations for the board and its peripherals.

help
Enable this if you want that the MXC NAND driver uses the in flash
Bad Block Table to know what blocks are bad instead of scanning the
entire flash looking for bad block markers.
