config ARMV7M_USEBASEPRI
	bool "Use BASEPRI Register"
	default n
	depends on ARCH_CORTEXM3 || ARCH_CORTEXM4
	---help---
		Use the BASEPRI register to enable and disable able interrupts.  By
 		default, the PRIMASK register is used for this purpose.  This
		usually results in hardfaults that are properly handling by the
		RTOS.  Using the BASEPRI register will avoid these hardfault.
		That is needed primarily for integration with some toolchains.

config ARCH_HAVE_CMNVECTOR
	bool

config ARMV7M_CMNVECTOR
	bool "Use common ARMv7-M vectors"
	default n
	depends on ARCH_HAVE_CMNVECTOR
	---help---
		Some architectures use their own, built-in vector logic.  Some use only
		the common vector logic.  Some can use either their own built-in vector
		logic or the common vector logic.  This applies only to ARMv7-M
		architectures.

config ARCH_FPU
	bool "FPU support"
	default y
	depends on ARCH_CORTEXM4
	---help---
		Build in support for the ARM Cortex-M4 Floating Point Unit (FPU).
		Check your chip specifications first; not all Cortex-M4 chips support the FPU.

config ARCH_HAVE_MPU
	bool

config ARMV7M_MPU
	bool "MPU support"
	default n
	depends on ARCH_HAVE_MPU
	---help---
		Build in support for the ARM Cortex-M3/4 Memory Protection Unit (MPU).
		Check your chip specifications first; not all Cortex-M3/4 chips support the MPU.

config ARCH_HAVE_LOWVECTORS
	bool

config ARCH_LOWVECTORS
	bool "Vectors in low memory"
	default n
	depends on ARCH_HAVE_LOWVECTORS
	---help---
		Support ARM vectors in low memory.

config ARCH_HAVE_MMU
	bool

config PGTABLE_VADDR
	hex "Page table virtual address"
	depends on ARCH_HAVE_MMU
	---help---
		Page table virtual address (might be defined in the board.h file).  Not
		applicable to all architectures.

config ARCH_ROMPGTABLE
	bool "ROM page table"
	default n
	depends on ARCH_HAVE_MMU
	---help---
		Support a fixed memory mapping use a (read-only) page table in ROM/FLASH.

config PAGING
	bool "On-demand paging"
	default n
	depends on ARCH_HAVE_MMU && !ARCH_ROMPGTABLE
	---help---
		If set =y in your configation file, this setting will enable the on-demand
		paging feature as described in http://www.nuttx.org/NuttXDemandPaging.html.

config BOARD_LOOPSPERMSEC
	int "Delay loops per millisecond"
	default 5000
	---help---
		Delay loops nust be calibrated for correct operation.

config ARCH_CALIBRATION
	bool "Calibrate delay loop"
	default n
	---help---
		Enables some built in instrumentation that causes a 100 second delay
		during boot-up.  This 100 second delay serves no purpose other than it
		allows you to calibratre BOARD_LOOPSPERMSEC.  You simply use a stop
		watch to measure the 100 second delay then adjust BOARD_LOOPSPERMSEC until
		the delay actually is 100 seconds.

config DEBUG_HARDFAULT
	bool "Verbose Hard-Fault Debug"
	default n
	depends on DEBUG && (ARCH_CORTEXM3 || ARCH_CORTEXM4)
	---help---
		Enables verbose debug output when a hard fault is occurs.  This verbose
		output is sometimes helpful when debugging difficult hard fault problems,
		but may be more than you typcially want to see.
