-/** @file
-  DMA abstraction library APIs. Based on UEFI PCI IO protocol DMA abstractions.
-  At some point these functions will probably end up in a non PCI protocol
-  for embedded systems.
-
-  DMA Bus Master Read Operation:
-    Call DmaMap() for MapOperationBusMasterRead.
-    Program the DMA Bus Master with the DeviceAddress returned by DmaMap().
-    Start the DMA Bus Master.
-    Wait for DMA Bus Master to complete the read operation.
-    Call DmaUnmap().
-
-  DMA Bus Master Write Operation:
-    Call DmaMap() for MapOperationBusMasterWrite.
-    Program the DMA Bus Master with the DeviceAddress returned by DmaMap().
-    Start the DMA Bus Master.
-    Wait for DMA Bus Master to complete the write operation.
-    Call DmaUnmap().
-
-  DMA Bus Master Common Buffer Operation:
-    Call DmaAllocateBuffer() to allocate a common buffer.
-    Call DmaMap() for MapOperationBusMasterCommonBuffer.
-    Program the DMA Bus Master with the DeviceAddress returned by DmaMap().
-    The common buffer can now be accessed equally by the processor and the DMA bus master.
-    Call DmaUnmap().
-    Call DmaFreeBuffer().
