Create dedicated function for xPortGetFreeHeapSize() that only reports on DRAM. NONOS SDK API system_get_free_heap_size() relies on xPortGetFreeHeapSize() for the free Heap size. Possible breaking change for multiple Heap Sketches calling system_get_free_heap_size(); it will now always report free DRAM Heap size. Update and export umm_free_heap_size_lw() to report the free Heap size of the current Heap. Updated ESP.getFreeHeap() to use umm_free_heap_size_lw(). Updated build options to supply exported umm_free_heap_size_lw() via either UMM_STATS or UMM_INFO. Improved build option support via the SketchName.ino.globals.h method for Heap options: UMM_INFO, UMM_INLINE_METRICS, UMM_STATS, UMM_STATS_FULL, UMM_BEST_FIT, and UMM_FIRST_FIT. While uncommon to change from the defaults, you can review umm_malloc_cfgport.h for more details, which may help reduce your Sketch's size in dire situations. Assuming you are willing to give up some functionality. For debugging UMM_STATS_FULL can offer additional stats, like Heap low water mark (umm_free_heap_size_min()).
