Testing DMA on MPC8555 board

Hi All,
i have an evaluation board with MPC8555 processor with kernel 2.6.27 the board contains DMA engine.

I want to test the DMA on my board by transferring data from a source to destination.

I dont know can i do this using the module of dmatest? i have inserted it but i did not get any sign that it works correct or not, so i m convinced that fsldma will achieve my aim.
the problem is that the function of
fsl_dma_self_test which is called in the function of
of_fsl_dma_chan_probe.
& i dont know how to trigger the probe function to work?
