To simplify the driver development let's split driver to library and platform code parts. It helps us to add PCI driver in future.

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

Say yes here to use big endian I/O access when reading and writing
|
|
to the DMA controller registers. This is needed on some platforms,
|
|
like the Atmel AVR32 architecture.
|
|
|
|
If unsure, use the default setting.
