+ * In order to avoid having objects dragged in just because main()
+ * calls their initialisation function, we allow each object to
+ * 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.
