It should happen automatically when nand_erase_opts() calls
chip->scan_bbt(), provided the driver set the NAND_USE_FLASH_BBT flag,
and that NAND_BBT_CREATE/NAND_BBT_WRITE are set in the nand_bbt_descr
(this is the case if the driver doesn't override the default
nand_bbt_descr).
Are you not seeing it happen? What version of U-Boot are you using,
with which NAND controller driver?
