- * In order to avoid having objects dragged in just because main()

- * specify that it has a function that must be called to initialise
- * that object.  The function call_init_fns() will call all the
- * included objects' initialisation functions.
- *
- * Objects that require initialisation should include init.h and
- * register the initialisation function using INIT_FN().
- *
- * Objects may register up to three functions: init, reset and exit.
- * init gets called only once, at the point that Etherboot is
- * initialised (before the call to main()).  reset gets called between
- * each boot attempt.  exit gets called only once, just before the
- * loaded OS starts up (or just before Etherboot exits, if it exits,
- * or when the PXE NBP calls UNDI_SHUTDOWN, if it's a PXE NBP).
- *
- * The syntax is:
- *   INIT_FN ( init_order, init_function, reset_function, exit_function );
- * where init_order is an ordering taken from the list below.  Any
- * function may be left as NULL.
