Subject: [PATCH 0/3] Enable DMA on STM32 MCU based on cortex-M7
Date: Tue, 12 Dec 2017 19:02:23 +0100 [thread overview]
Message-ID: <1513101746-18030-1-git-send-email-alexandre.torgue@st.com> (raw)
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.
Regards
Alex
