 * The CoreSight STM supports guaranteed and invariant timing
 * transactions.  Guaranteed transactions are guaranteed to be
 * traced, this might involve stalling the bus or system to
 * ensure the transaction is accepted by the STM.  While invariant
 * timing transactions are not guaranteed to be traced, they
 * will take an invariant amount of time regardless of the
 * state of the STM.
