/* This file is only a thin shell that includes the correct DMA implementation
* for the selected STM32 family. The correct file cannot be selected by
* the make system because it needs the intelligence that only exists in
* chip.h that can associate an STM32 part number with an STM32 family.
*
* The STM32 F4 DMA differs from the F1 DMA primarily in that it adds the
* concept of "streams" that are used to associate DMA sources with DMA
* channels.
