+config MM_REGIONS
+	int "number of memory regions"
+	default 1
+	---help---
+	If the architecture includes multiple
+	regions of memory to allocate from, this specifies the
+	number of memory regions that the memory manager must
+	handle and enables the API mm_addregion(start, end);
+	
+config MSEC_PER_TICK
+	int "tick timer"
+	default 10
+	---help---
+	The default system timer is 100Hz
+	or MSEC_PER_TICK=10.  This setting may be defined to
+	inform NuttX that the processor hardware is providing
+	system timer interrupts at some interrupt interval other
+	than 10 msec.
+	
+config RR_INTERVAL
+	int "round robin timeslice"
+	default 0
+	---help---

+	this number of milliseconds;  Round robin scheduling can
+	be disabled by setting this value to zero.

+	This setting is only used if priority
+	inheritance is enabled.  It defines the maximum number of
+	different threads (minus one) that can take counts on a
+	semaphore with priority inheritance support.  This may be

+	are only using semaphores as mutexes (only one holder) OR
+	if no more than two threads participate using a counting
+	semaphore.

+	default 16
+	depends on PRIORITY_INHERITANCE
+	---help---

+config DISABLE_OS_API
+	bool "disable os api"
+	default n
+	---help---
+	The following can be used to disable categories of
+	APIs supported by the OS.  If the compiler supports
+	weak functions, then it should not be necessary to
+	disable functions unless you want to restrict usage
+	of those APIs.
+	
+	There are certain dependency relationships in these
+	features.
+

+	  waiting for queues to become full or empty.
+	o pthread_condtimedwait() depends on signals to wake
+	  up waiting tasks.
