+	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.
