config CPU_HAS_ARM_MPU
	bool
	select CPU_HAS_MPU
	help
	  This option is enabled when the CPU has a Memory Protection Unit (MPU)
	  in ARM flavor.

config CPU_HAS_NXP_MPU
	bool
	select CPU_HAS_MPU
	help
	  This option is enabled when the CPU has a Memory Protection Unit (MPU)
	  in NXP flavor.

config CPU_HAS_CUSTOM_FIXED_SOC_MPU_REGIONS
	bool "Custom fixed SoC MPU region definition"
	help
	  If enabled, this option signifies that the SoC will
	  define and configure its own fixed MPU regions in the
	  SoC definition. These fixed MPU regions are currently
	  used to set Flash and SRAM default access policies and
	  they are programmed at boot time.

config CPU_HAS_ARM_SAU
	bool
	select CPU_HAS_TEE
	help
	  MCU implements the ARM Security Attribution Unit (SAU).

config CPU_HAS_NRF_IDAU
	bool
	depends on SOC_SERIES_NRF91X || SOC_NRF5340_CPUAPP
	select CPU_HAS_TEE
	help
	  MCU implements the nRF (vendor-specific) Security Attribution Unit.
	  (IDAU: "Implementation-Defined Attribution Unit", in accordance with
	  ARM terminology).

config CPU_HAS_FPU_DOUBLE_PRECISION
	bool
	depends on CPU_CORTEX_M7
	select CPU_HAS_FPU
	help
	  When enabled, indicates that the SoC has a double
	  floating point precision unit.

config HAS_SWO
	bool
	help
	  When enabled, indicates that SoC has an SWO output

config SOC_PART_NUMBER
	string
	help
	  This string holds the full part number of the SoC. It is a hidden option
	  that you should not set directly. The part number selection choice defines
	  the default value for this string.
