372	  If a data is stalled inside asynchronous bridge because of back

374	  misalignment that will corrupt next transfers on that data path
375	  until next reset of the system (No recovery procedure once the
376	  issue is hit, the path remains consistently broken). Async bridge
377	  can be found on path between MPU to EMIF and MPU to L3 interconnect.
378	  This situation can happen only when the idle is initiated by a
379	  Master Request Disconnection (which is trigged by software when
380	  executing WFI on CPU).
381	  The work-around for this errata needs all the initiators connected
382	  through async bridge must ensure that data path is properly drained
383	  before issuing WFI. This condition will be met if one Strongly ordered
384	  access is performed to the target right before executing the WFI.
385	  In MPU case, L3 T2ASYNC FIFO and DDR T2ASYNC FIFO needs to be drained.
386	  IO barrier ensure that there is no synchronisation loss on initiators
387	  operating on both interconnect port simultaneously.
