329/* 329/*
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,
