I don't understand why we need to have the MX7_SEC config options in imx-common. There are already config options for all the secure/non-secure boot stuff in arch/arm/cpu/armv7/Kconfig. I suggest to remove MX7_SEC, and add "default y if ARCH_MX7" for the existing config option ARMV7_BOOT_SEC_DEFAULT in arch/arm/cpu/armv7/Kconfig. -- Stefan

Yes, I was not aware of the ARMV7_BOOT_SEC_DEFAULT option. I sent a new version as suggested, thanks.

Commit be1a17ff689 ("mx7_common: use Kconfig for ARMv7 non-secure mode") breaks the boot of a NXP 4.1.15 kernel using mx7dsabresd_secure_defconfig target. This problem happens because after this commit non-secure mode is always selected at CPU level. Fix this by only selecting CPU_V7_HAS_NONSEC if the MX7_SEC board option is unset.
