1.01a nm     03/05/2012 Initializing DmaCmd structure compatible to armcc.
                        Modified base address to secure register base
                        address.
1.02a sg     05/16/2012 Some code cleanup and reorganisation of the
                  functions within the example.
1.06a kpc    04/24/2012 Modified the APIs to make this file compatible with
                        peripheral test suite.
2.1   kpc    08/23/2014 Fixed IAR compiler reported error.
2.3   ms     01/23/17  Modified xil_printf statement in main function to
