/* This file is only a thin shell that includes the correct DMA
|
|
* implementation for the selected STM32 IP core:
|
|
* - STM32 DMA IP version 1 - F0, F1, F3, G4, L0, L1, L4
|
|
* - STM32 DMA IP version 2 - F2, F4, F7, H7
|
|
*
|
|
* The STM32 DMA IPv2 differs from the STM32 DMA IPv1 primarily in that it
|
|
* adds the concept of "streams" that are used to associate DMA sources with
|
|
* DMA channels.
