config ARMV7M_STACKCHECK
	bool "Check for stack overflow on each function call"
	default n
	depends on ARMV7M_HAVE_STACKCHECK
	---help---
		This check uses R10 to check for a stack overflow within each
		function call. This has performances and code size impacts, but it
		will be able to catch hard to find stack overflows.

		Currently only available only for the STM32, SAM3/4 and SAMA5D
		architectures.  The changes are not complex and patches for
		other architectures will be accepted.

		This option requires that you are using a GCC toolchain and that
		you also include -finstrument-functions in your CFLAGS when you
		compile.  This addition to your CFLAGS should probably be added
		to the definition of the CFFLAGS in your board Make.defs file.

		Enable hooks to support ITM syslog output.  This requires additional

		for additional initialization information.
