+       help
+         Some peripherals support DMA from a subset of physically
+         addressable memory only.  To support such peripherals, the
+         bounce buffer API uses a temporary buffer: it copies data
+         to/from DMA regions while managing cache operations.
+
+         A second possible use of bounce buffers is their ability to
+         provide aligned buffers for DMA operations.
