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