# # For a description of the syntax of this configuration file, # see misc/tools/kconfig-language.txt. # 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 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.
