With this patch applied I get:

$ make imx_v6_v7_defconfig
warning: (SOC_IMX6Q && ARCH_TEGRA_2x_SOC && ARCH_TEGRA_3x_SOC) selects
ARM_ERRATA_751472 which has unmet direct dependencies (CPU_V7 &&
!ARCH_MULTIPLATFORM)
warning: (SOC_IMX6Q && ARCH_TEGRA_3x_SOC) selects ARM_ERRATA_743622
which has unmet direct dependencies (CPU_V7 && !ARCH_MULTIPLATFORM)

#
# configuration written to .config

Any suggestion?
