+ help
+ This option enables the workaround for the 775420 Cortex-A9 (r2p2,
+ r2p6,r2p8,r2p10,r3p0) erratum. In case a date cache maintenance
+ operation aborts with MMU exception, it might cause the processor
+ to deadlock. This workaround puts DSB before executing ISB if
+ an abort may occur on cache maintenance.
