	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).

config ARCH_LOWVECTORS
	bool "Vectors in low memory"
	default n

	---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

	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 ARCH_IRQPRIO

		Select if your board supports interrupt prioritization.

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.
