31 * state that we are at, and the action that we are about to perform. For
32 * errors, we issue an error for an item when it fails. Therefore the

76 * this case we are reporting completion of a particular stage.
77 * This should probably change in he x86 code (which doesn't report
78 * errors in any case), but discussion this can perhaps wait until we
79 * have a generic board implementation.
