/*
        * By default, all DMA modes are disabled for the MPC5200.  Some
        * boards don't have the required signals routed to make DMA work.
        * Also, the MPC5200B has a silicon bug that causes data corruption
        * with UDMA if it is used at the same time as the LocalPlus bus.
        *
        * Instead of trying to guess what modes are usable, check the
        * ATA device tree node to find out what DMA modes work on the board.
        * UDMA/MWDMA modes can also be forced by adding "libata.force=<mode>"
        * to the kernel boot parameters.
        *
        * The MPC5200 ATA controller supports MWDMA modes 0, 1 and 2 and
        * UDMA modes 0, 1 and 2.
