Exactly. The IFC controller supports both NAND and NOR flashes. Since
commit ea0c0ad6b6eb ("memory: Enable compile testing for most of the drivers"),
it has not been possible to use IFC controller for NOR flashes without
selecting the IFC NAND driver (CONFIG_MTD_NAND_FSL_IFC), which is
obviously not how it is supposed to be.
