The current code passes TO number to imx-sdma driver to load different firmware for different TO. That means we have to prepare 3 identical firmwares, sdma-imx25-to1.bin sdma-imx25-to2.bin and sdma-imx25-to3.bin, to have the kernel capable of running on all three TOs. This just makes no sense. The patch removes the TO number passing and get the default TO1 version of sdma firmware work for all TOs.
