-  @param  HostAddress           The system memory address to map to the DMA controller.

-  @param  NumberOfBytes         On input the number of bytes to map. On output the number of bytes

-                                that were mapped.

-  @param  DeviceAddress         The resulting map address for the bus master controller to use to

-  @param  Mapping               A resulting value to pass to Unmap().

-

-  @retval EFI_SUCCESS           The range was mapped for the returned NumberOfBytes.

-  @retval EFI_UNSUPPORTED       The HostAddress cannot be mapped as a common buffer.

-  @retval EFI_INVALID_PARAMETER One or more parameters are invalid.

-  @retval EFI_OUT_OF_RESOURCES  The request could not be completed due to a lack of resources.

-  @retval EFI_DEVICE_ERROR      The system hardware could not map the requested address.
