The simplest way to activate the FLASH based bad block table support
- is to set the option NAND_USE_FLASH_BBT in the bbt_option field of
+ is to set the option NAND_BBT_USE_FLASH in the bbt_option field of
the nand chip structure before calling nand_scan(). For AG-AND
chips is this done by default.
This activates the default FLASH based bad block table functionality
