Since the merge of V7M support in to the kernel it is possible to select MPU support on V7M. This patch ensures that until MPU support for M-class processors is implemented, the MPU can only be selected with R-class CPUs Signed-off-by: Jonathan Austin Acked-by: Uwe Kleine-König --- diff --git a/arch/arm/Kconfig-nommu b/arch/arm/Kconfig-nommu index db597e1c7572..aed66d5df7f1 100644 --- a/arch/arm/Kconfig-nommu +++ b/arch/arm/Kconfig-nommu @@ -53,6 +53,7 @@ config REMAP_VECTORS_TO_RAM config ARM_MPU bool 'Use the ARM v7 PMSA Compliant MPU' + depends on CPU_V7 default y help Some ARM systems without an MMU have instead a Memory Protection
