330 | * The caches on some architectures aren't dma-coherent and have need to | ||
331 | * handle this in software. There are three types of operations that | ||
332 | * can be applied to dma buffers. | ||
333 | * | ||
334 | * - dma_cache_wback_inv(start, size) makes caches and RAM coherent by | ||
335 | * writing the content of the caches back to memory, if necessary. | ||
336 | * The function also invalidates the affected part of the caches as | ||
337 | * necessary before DMA transfers from outside to memory. | ||
338 | * - dma_cache_inv(start, size) invalidates the affected parts of the | ||
339 | * caches. Dirty lines of the caches may be written back or simply | ||
340 | * be discarded. This operation is necessary before dma operations | ||
341 | * to the memory. | ||
342 | * - dma_cache_wback(start, size) writes back any dirty lines but does | ||
343 | * not invalidate the cache. This can be used before DMA reads from | ||
344 | * memory, | ||
