| 422 | If a data is stalled inside asynchronous bridge because of back | |
| 423 | pressure, it may be accepted multiple times, creating pointer | |
| 424 | misalignment that will corrupt next transfers on that data path | |
| 425 | until next reset of the system (No recovery procedure once the | |
| 426 | issue is hit, the path remains consistently broken). Async bridge | |
| 427 | can be found on path between MPU to EMIF and MPU to L3 interconnect. | |
| 428 | This situation can happen only when the idle is initiated by a | |
| 429 | Master Request Disconnection (which is trigged by software when | |
| 430 | executing WFI on CPU). | |
| 431 | The work-around for this errata needs all the initiators connected | |
| 432 | through async bridge must ensure that data path is properly drained | |
| 433 | before issuing WFI. This condition will be met if one Strongly ordered | |
| 434 | access is performed to the target right before executing the WFI. | |
| 435 | In MPU case, L3 T2ASYNC FIFO and DDR T2ASYNC FIFO needs to be drained. | |
| 436 | IO barrier ensure that there is no synchronisation loss on initiators | |
| 437 | operating on both interconnect port simultaneously. | |
