361*137d105dSSantosh Shilimkar	  If a data is stalled inside asynchronous bridge because of back
362*137d105dSSantosh Shilimkar	  pressure, it may be accepted multiple times, creating pointer
363*137d105dSSantosh Shilimkar	  misalignment that will corrupt next transfers on that data path
364*137d105dSSantosh Shilimkar	  until next reset of the system (No recovery procedure once the
365*137d105dSSantosh Shilimkar	  issue is hit, the path remains consistently broken). Async bridge
366*137d105dSSantosh Shilimkar	  can be found on path between MPU to EMIF and MPU to L3 interconnect.
367*137d105dSSantosh Shilimkar	  This situation can happen only when the idle is initiated by a

370*137d105dSSantosh Shilimkar	  The work-around for this errata needs all the initiators connected
371*137d105dSSantosh Shilimkar	  through async bridge must ensure that data path is properly drained
372*137d105dSSantosh Shilimkar	  before issuing WFI. This condition will be met if one Strongly ordered
373*137d105dSSantosh Shilimkar	  access is performed to the target right before executing the WFI.
