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.
