config MM_SMALL
	bool "Small memory model"
	default n
	---help---
		Each memory allocation has a small allocation overhead.  The size
		of that overhead is normally determined by the "width" of the
		address support by the MCU.  MCUs that support 16-bit addressability
		have smaller overhead than devices that support 32-bit addressability.
		However, there are many MCUs that support 32-bit addressability *but*
		have internal SRAM of size less than or equal to 64Kb.  In this case,
		CONFIG_MM_SMALL can be defined so that those MCUs will also benefit
		from the smaller, 16-bit-based allocation overhead.

config MM_REGIONS
	int "Number of memory regions"
	default 1
	---help---
		If the architecture includes multiple, non-contiguous 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 ARCH_HAVE_HEAP2
	bool

config HEAP2_BASE
	hex "Start address of second heap region"
	default 0x00000000
	depends on ARCH_HAVE_HEAP2
	---help---
		The base address of the second heap region.

config HEAP2_SIZE
	int "Size of the second heap region"
	default 0
	depends on ARCH_HAVE_HEAP2
	---help---
		The size of the second heap region.

config GRAN
	bool "Enable Granule Allocator"
	default n
	---help---
		Enable granual allocator support.  Allocations will be aligned to the
		granule size; allocations will be in units of the granule size.
		Larger granules will give better performance and less overhead but
		more losses of memory due to alignment and quantization waste.

		NOTE: The current implementation also restricts the maximum
		allocation size to 32 granaules.  That restriction could be
		eliminated with some additional coding effort.

config GRAN_SINGLE
	bool "Single Granule Allocator"
	default n
	depends on GRAN
	---help---
		Select if there is only one instance of the granule allocator (i.e.,
		gran_initialize will be called only once. In this case, (1) there
		are a few optimizations that can can be done and (2) the GRAN_HANDLE
		is not needed.

config GRAN_INTR
	bool "Interrupt level support"
	default n
	depends on GRAN
	---help---
		Normally mutual exclusive access to granule allocator data is assured
		using a semaphore.  If this option is set then, instead, mutual
		exclusion logic will disable interrupts.  While this options is more
		invasive to system performance, it will also support use of the granule
		allocator from interrupt level logic.

config DEBUG_GRAN
	bool "Granule Allocator Debug"
	default n
	depends on GRAN && DEBUG
	---help---
		Just like CONFIG_DEBUG_MM, but only generates ouput from the gran
		allocation logic.
