371137d105dSSantosh Shilimkar	  If a data is stalled inside asynchronous bridge because of back
372137d105dSSantosh Shilimkar	  pressure, it may be accepted multiple times, creating pointer
373137d105dSSantosh Shilimkar	  misalignment that will corrupt next transfers on that data path
374137d105dSSantosh Shilimkar	  until next reset of the system (No recovery procedure once the
375137d105dSSantosh Shilimkar	  issue is hit, the path remains consistently broken). Async bridge
376137d105dSSantosh Shilimkar	  can be found on path between MPU to EMIF and MPU to L3 interconnect.
377137d105dSSantosh Shilimkar	  This situation can happen only when the idle is initiated by a
378137d105dSSantosh Shilimkar	  Master Request Disconnection (which is trigged by software when
379137d105dSSantosh Shilimkar	  executing WFI on CPU).
380137d105dSSantosh Shilimkar	  The work-around for this errata needs all the initiators connected
381137d105dSSantosh Shilimkar	  through async bridge must ensure that data path is properly drained
382137d105dSSantosh Shilimkar	  before issuing WFI. This condition will be met if one Strongly ordered
383137d105dSSantosh Shilimkar	  access is performed to the target right before executing the WFI.
384137d105dSSantosh Shilimkar	  In MPU case, L3 T2ASYNC FIFO and DDR T2ASYNC FIFO needs to be drained.
385137d105dSSantosh Shilimkar	  IO barrier ensure that there is no synchronisation loss on initiators
