[PATCH 0/3] Enable DMA on STM32 MCU based on cortex-M7

[Alexandre Torgue]

This series enable DMA on several STM32 MCU based on cortex-M7.
To make it possible, a dedicated dma pool memory area has to be
created. This patchset activate also ARM_MPU flag which will configure 
MPU (Memory Protection Unit) according to devicetree information (mem
and dma-pool). Note that on cortex-M7 DMA has to use a NO cache-able 
memory region.
