powerpc: select MEMORY for FSL_IFC to not break existing .config files
commit d2ae2e20fbdde5a65f3a5a153044ab1e5c53f7cc ("driver/memory:Move Freescale IFC driver to a common driver") introduces this build regression into the mpc85xx_defconfig: drivers/built-in.o: In function `fsl_ifc_nand_remove': drivers/mtd/nand/fsl_ifc_nand.c:1147: undefined reference to `fsl_ifc_ctrl_dev' drivers/mtd/nand/fsl_ifc_nand.c:1147: undefined reference to `fsl_ifc_ctrl_dev' drivers/built-in.o: In function `fsl_ifc_nand_probe': drivers/mtd/nand/fsl_ifc_nand.c:1031: undefined reference to `fsl_ifc_ctrl_dev' drivers/mtd/nand/fsl_ifc_nand.c:1031: undefined reference to `fsl_ifc_ctrl_dev' drivers/built-in.o: In function `match_bank': drivers/mtd/nand/fsl_ifc_nand.c:1013: undefined reference to `convert_ifc_address' drivers/built-in.o: In function `fsl_ifc_nand_probe': drivers/mtd/nand/fsl_ifc_nand.c:1059: undefined reference to `fsl_ifc_ctrl_dev' drivers/mtd/nand/fsl_ifc_nand.c:1080: undefined reference to `fsl_ifc_ctrl_dev' drivers/mtd/nand/fsl_ifc_nand.c:1069: undefined reference to `fsl_ifc_ctrl_dev' drivers/mtd/nand/fsl_ifc_nand.c:1069: undefined reference to `fsl_ifc_ctrl_dev' make: *** [vmlinux] Error 1 This happens because there is nothing to descend us into the drivers/memory directory in the mpc85xx_defconfig. It wasn't selecting CONFIG_MEMORY. So we never built drivers/memory/fsl_ifc.o and so we have nothing to link the above symbols against. Since the goal of the original commit was to relocate the driver to an arch independent location, it only makes sense to relocate the Kconfig setting there as well. But that alone won't fix the build failure; for that we ensure whoever selects FSL_IFC also selects MEMORY.
