NAME
       nand_scan_bbt - [NAND Interface] scan, find, read and maybe create bad block table(s)

SYNOPSIS
       int nand_scan_bbt(struct mtd_info * mtd, struct nand_bbt_descr * bd);

ARGUMENTS
       mtd
           MTD device structure

       bd
           descriptor for the good/bad block search pattern

DESCRIPTION
       The function checks, if a bad block table(s) is/are already available. If not it scans the
       device for manufacturer marked good / bad blocks and writes the bad block table(s) to the
       selected place.

       The bad block table memory is allocated here. It must be freed by calling the
       nand_free_bbt function.
