  FILE    : startcf.h
  PURPOSE : startup code for ColdFire
  LANGUAGE: C


  Notes:
        1) Default entry point is _startup. 
           . disable interrupts
           . the SP is set to __SP_AFTER_RESET
           . SP must be initialized to valid memory 
             in case the memory it points to is not valid using MEMORY_INIT macro
        2) __initialize_hardware is called. Here you can initialize memory and some peripherics
           at this point global variables are not initialized yet
        3) After __initialize_hardware memory is setup; initialize SP to _SP_INIT and perform 
           needed initialisations for the language (clear memory, data rom copy).
        4) void __initialize_system(void); is called
           to allow additional hardware initialization (UART, GPIOs, etc...)
        5) Jump to main
