This should boost 36218862cbeSPaul Walmsley SDRAM performance at lower CORE OPPs. There are relatively few 36318862cbeSPaul Walmsley users who will wish to say yes at this point - almost everyone will 36418862cbeSPaul Walmsley wish to say no. Selecting yes without understanding what is 36518862cbeSPaul Walmsley going on could result in system crashes; 36618862cbeSPaul Walmsley 367137d105dSSantosh Shilimkarconfig OMAP4_ERRATA_I688 3682ec1fc4eSSantosh Shilimkar bool "OMAP4 errata: Async Bridge Corruption" 3692ec1fc4eSSantosh Shilimkar depends on ARCH_OMAP4 370137d105dSSantosh Shilimkar select ARCH_HAS_BARRIERS 371137d105dSSantosh Shilimkar help 372137d105dSSantosh Shilimkar If a data is stalled inside asynchronous bridge because of back 373137d105dSSantosh Shilimkar pressure, it may be accepted multiple times, creating pointer 374137d105dSSantosh Shilimkar misalignment that will corrupt next transfers on that data path 375137d105dSSantosh Shilimkar until next reset of the system (No recovery procedure once the 376137d105dSSantosh Shilimkar issue is hit, the path remains consistently broken). Async bridge 377137d105dSSantosh Shilimkar can be found on path between MPU to EMIF and MPU to L3 interconnect. 378137d105dSSantosh Shilimkar This situation can happen only when the idle is initiated by a 379137d105dSSantosh Shilimkar Master Request Disconnection (which is trigged by software when 380137d105dSSantosh Shilimkar executing WFI on CPU). 381137d105dSSantosh Shilimkar The work-around for this errata needs all the initiators connected 382137d105dSSantosh Shilimkar through async bridge must ensure that data path is properly drained 383137d105dSSantosh Shilimkar before issuing WFI.
