CRISv32: add cache flush operations
These are needed due to a cache bug, and can be used to make sure that the DMA descriptors are flushed to memory and can be safely handled by DMA. flush_dma_descr - Flush one DMA descriptor. flush_dma_list - Flush a complete list of DMA descriptors. cris_flush_cache - Flush the complete cache. cris_flush_cache_range - Flush only the specified range Signed-off-by: NJesper Nilsson <jesper.nilsson@axis.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
