    Subject: genericarm64: drop CONFIG_MTD_NAND_FSL_IFC
    Date: Tue, 13 Aug 2024 15:17:10 -0400

    We are getting the following warning in recent 6.6+ kernels:

        WARNING: linux-yocto-6.6.45+git-r0 do_kernel_configcheck: [kernel config]: specified values did not make it into the kernel's final configuration:

        [NOTE]: 'CONFIG_MTD_NAND_FSL_IFC' last val (y) and .config val (n) do not match
        [INFO]: CONFIG_MTD_NAND_FSL_IFC : n
        [INFO]: raw config text:

            config MTD_NAND_FSL_IFC
                    tristate "Freescale IFC NAND controller"
                    depends on (FSL_SOC || ARCH_LAYERSCAPE || SOC_LS1021A || COMPILE_TEST) && HAS_IOMEM && FSL_IFC && MTD_RAW_NAND && MTD
                    help
                      Various Freescale chips e.g P1010, include a NAND Flash machine
                      with built-in hardware ECC capabilities.
                      Enabling this option will enable you to use this to control
                      external NAND devices.

            Config 'MTD_NAND_FSL_IFC' has the following Direct dependencies (MTD_NAND_FSL_IFC=n):
                    FSL_SOC(undefined/n) || ARCH_LAYERSCAPE(=y) || SOC_LS1021A(undefined/n) || COMPILE_TEST(=n) (=y) && HAS_IOMEM(=y) && FSL_IFC(=n) && MTD_RAW_NAND(=y) && MTD(=y)
            Parent dependencies are:
                 SOC_LS1021A [SOC_LS1021A] MTD [y] ARCH_LAYERSCAPE [y] HAS_IOMEM [y] FSL_SOC [FSL_SOC] COMPILE_TEST [n] MTD_RAW_NAND [y] FSL_IFC [n]
        [INFO]: config 'CONFIG_MTD_NAND_FSL_IFC' was set, but it wasn't assignable, check (parent) dependencies

    The most significant missing option that is disabling this config value
    is FSL_SOC, which is only defined in arch/powerpc.

    As such, there's no sense keeping this option in the genericarm64 config
    as it is only enabled via arch/powerpc.
