VPDMA buffer will be used by CPU as well as by the VPDMA. CPU will write/update the VPDMA descriptors containing data about the video buffer DMA addresses. VPDMA will write the "write descriptor" containing the data about the DMA operation. When mapping/unmapping the buffer, driver has to take care of WriteBack and invalidation of the cache so that all the coherency is maintained from both directions. Use DMA_BIDIRECTIONAL to maintain coherency between CPU and VPDMA.
