SYNOPSIS

ARGUMENTS

12       mtd
13           MTD device structure

15       ofs
16           offset from device start

DESCRIPTION

19       This is the default implementation, which can be overridden by a
20       hardware specific driver. We try operations in the following order,
21       according to our bbt_options (NAND_BBT_NO_OOB_BBM and
22       NAND_BBT_USE_FLASH): (1) erase the affected block, to allow OOB marker
23       to be written cleanly (2) update in-memory BBT (3) write bad block
24       marker to OOB area of affected block (4) update flash-based BBT Note
25       that we retain the first error encountered in (3) or (4), finish the
26       procedures, and dump the error in the end.
