   Thank you @anjiahao1 :-) I saw the mailing list discussion.. your solution 
seems a bit different:
   * `heap = mm_memalign(heap, MM_ALIGN, sizeof(struct mm_heap_s));` is 
replaced with `heap = mm_malloc(heap, sizeof(struct mm_heap_s));`
   
   While KR proposes adding new kconfig option to disable unused code at all in 
the DEFAULT_SMALL builds:
   - new Kconfig option MM_DISABLE_INIT_HEAP_POINTER, defaults to
   DEFAULT_SMALL
   - rptun driver depends on !MM_DISABLE_INIT_HEAP_POINTER
   
   This does not look functionally the same.. KR proposes disabling unused code 
while you change heap allocation method.. and misalignment of the heap may 
cause problems on some real world hardware?
