Yes, that's correct (unless you need to access NAND only from SPL). But if any
board booting from NAND had a 16-bit NAND, CONFIG_SYS_NAND_BUSWIDTH_16 would
have to be defined, which no board does, so none of these boards needs
CONFIG_SYS_NAND_BUSWIDTH_16BIT either. And the rest of the explanation is what
Fabio has just said.

Best regards,
Benoît
