- The Snoop Control Unit on ARM11MPCore does not detect the
- cache maintenance operations and the dma_{map,unmap}_area()
- 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).
