NAND_DEFAULT_BLOCK_M(9) Internal Functions Provided NAND_DEFAULT_BLOCK_M(9)NAMEnand_default_block_markbad - [DEFAULT] mark a block bad
SYNOPSIS
int nand_default_block_markbad(struct mtd_info * mtd, loff_t ofs);
ARGUMENTS
mtd
MTD device structure
ofs
offset from device start
DESCRIPTION
This is the default implementation, which can be overridden by a
hardware specific driver. We try operations in the following order,
according to our bbt_options (NAND_BBT_NO_OOB_BBM and
NAND_BBT_USE_FLASH): (1) erase the affected block, to allow OOB marker
to be written cleanly (2) update in-memory BBT (3) write bad block
marker to OOB area of affected block (4) update flash-based BBT Note
that we retain the first error encountered in (3) or (4), finish the
procedures, and dump the error in the end.
