+<section id="GUID-04298BEC-F064-40C4-9A8C-DFB15953C85B"><title>Purpose</title><p>Direct Memory Access (DMA) channels allow you to copy data between
+memory locations, or between memory and peripherals, while minimizing
+the use of  the CPU. The transfer operation is performed in hardware
+by the DMA controller. The purpose of the DMA platform service is
+to provide a common interface between hardware and device drivers
+which use DMA.</p><p>The framework is divided into a platform-independent
+layer and a platform-specific layer, with the DMA platform service
+being the interface between the two. The framework presents an API
+for use by device drivers and other client applications which transfer
+data by DMA. The PSL must be implemented by hardware developers to
+provide the same functionality on multiple platforms.</p></section>
