The MMCIF controller on sh-mobile platforms can use the DMA controller for data transfers. Interface to the SH dmaengine driver to enable DMA. We also have to lower the maximum number of segments to match with the number od DMA descriptors on SuperH, this doesn't significantly affect driver's PIO performance.
