Function description:
---------------------

This demo shows **memory to memory** data transfer working in normal mode.

The source & destination address is increasing automatically:

* Initialize & configure the udma.
* Start dma data transfer.
* Compare the data in destination address with the data in source address after transformation done.

Main Configuration:
-------------------

Udma m2m configure

Test result:
------------

If the data writted to buffer by DMA is same as the source data, then print pass, if not print fail.
