NAND_BLOCK_MARKBAD_L(9)            Internal Functions Provided            NAND_BLOCK_MARKBAD_L(9)



NAME
       nand_block_markbad_lowlevel - mark a block bad

SYNOPSIS
       int nand_block_markbad_lowlevel(struct mtd_info * mtd, loff_t ofs);

ARGUMENTS
       mtd
           MTD device structure

       ofs
           offset from device start

DESCRIPTION
       This function performs the generic NAND bad block marking steps (i.e., bad block table(s)
       and/or marker(s)). We only allow the hardware driver to specify how to write bad block
       markers to OOB (chip->block_markbad).

       We try operations in the following order: (1) erase the affected block, to allow OOB
       marker to be written cleanly (2) write bad block marker to OOB area of affected block
       (unless flag NAND_BBT_NO_OOB_BBM is present) (3) update the BBT Note that we retain the
       first error encountered in (2) or (3), finish the procedures, and dump the error in the
       end.
