[U-Boot] [PATCH 2/4] mtd: nand: mxs_nand: allow to enable BBT support

[Stefan Agner]

From: Stefan Agner <stefan.agner at toradex.com>

Add config option which allows to enable on flash bad block table
support. This has the same effect as when using the device tree
property "nand-on-flash-bbt" in Linux.
