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


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


struct mtd_info * mtd

MTD device structure

struct nand_bbt_descr * bd

descriptor for the good/bad block search pattern


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.
