Look at the file there are other points where this ifdef is used for exactly the same reason and please check this commit commit fa87360b3ae28639f72e1c665b0631436693f60f Author: Roger Quadros <[email protected]> Date: Tue Dec 20 12:21:57 2022 +0200 mtd: rawnand: nand_base: Allow base driver to be used in SPL without nand_bbt nand_bbt.c is not being built with the nand_base driver during SPL build. This results in build failures if we try to access any nand_bbt related functions. Don't use any nand_bbt functions for SPL build.
