743 | The Snoop Control Unit on ARM11MPCore does not detect the | ||
744 | cache maintenance operations and the dma_{map,unmap}_area() | ||
745 | functions may leave stale cache entries on other CPUs. By | ||
746 | enabling this option, Read or Write For Ownership in the ARMv6 | ||
747 | DMA cache maintenance functions is performed. These LDR/STR | ||
748 | instructions change the cache line state to shared or modified | ||

750 | |||
751 | Note that the workaround is only valid on processors that do | ||

753 | processors, if cache maintenance operations are not broadcast | ||
