    13 Memory Access) hardware.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

    14 <p> Device drivers use DMA to copy data quickly between memory locations,

    15 and between memory and peripherals. This section describes how to create a

    16 port of it for your phone hardware. The Device Driver Guide documentation

    17 describes how to use the DMA Framework from a device driver. </p>

    18 <p>The DMA Framework provides a Platform Independent Layer. You must provide

    19 a Platform Specific Layer to implement the interface to the DMA Controller

    20 hardware on your phone. </p>
