Added a lot of #ifndef , extern C, Move inside from ARMSRC -> THUMBS, which made the compiled image smaller.. I don't know if it broke anything. Moved MF_DBGLEVEL definitions into common.h Moved print_result from util.c into appmain.c Also split up some struct typedef into header files so they could be reused in other code places. ''' danger ''' this might have broken stuff...
