  15           Support the Synopsys DesignWare AHB DMA controller. This
  16           can be integrated in chips such as the Atmel AT32ap7000.

  23           Support the Synopsys DesignWare AHB DMA controller on the
  24           platfroms that enumerate it as a PCI device. For example,
  25           Intel Medfield has integrated this GPDMA controller.

  32           Say yes here to use big endian I/O access when reading and writing
  33           to the DMA controller registers. This is needed on some platforms,
  34           like the Atmel AVR32 architecture.

  36           If unsure, use the default setting.
