This DMA engine is intended to use with AMD NTB IP and not for general purpose DMA, hence set the cap as DMA_PRIVATE. Otherwise this DMA engine will be used for system DMA. Please correct me if my understanding is not right. Also, I have implemented all of the comments for this patch except this. if this is fine, will send the next version for review.
