MXC: mach-mx31_3ds: Add support for on board NAND Flash.
Since the using of Bad Block Table is not constantly a good behave I had made it configurable. Signed-off-by: Alberto Panizzo <maramaopercheseimorto@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

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.
