This line could be simplified. But it's also weird now that you can
select CONFIG_MTD_NAND_STM_BCH_BBT, but that won't build the BBT code if
MTD_NAND_STM_BCH=n. So I'd suggest the following instead:
depends on MTD_NAND_STM_BCH
default y
Or maybe this could be more explicit about the default:
depends on MTD_NAND_STM_BCH
default MTD_NAND_STM_BCH
