functions may leave stale cache entries on other CPUs. By
|

enabling this option, Read or Write For Ownership in the ARMv6
|
||||
DMA cache maintenance functions is performed. These LDR/STR
|
||||
instructions change the cache line state to shared or modified
|
||||
so that the cache operation has the desired effect.
|

|

Note that the workaround is only valid on processors that do
|

not perform speculative loads into the D-cache. For such
|

processors, if cache maintenance operations are not broadcast
|
||||
in hardware, other workarounds are needed (e.g. cache
|

maintenance broadcasting in software via FIQ).
