2022-09-04docs: arm: stm32: introduce STM32 DMA-MDMA chaining featureAmelie Delaunay1-0/+415
STM32 DMA-MDMA chaining feature is available on STM32 SoCs which embed STM32 DMAMUX, DMA and MDMA controllers. It is the case on STM32MP1 SoCs but also on STM32H7 SoCs. But focus is on STM32MP1 SoCs, using DDR. This documentation aims to explain how to use STM32 DMA-MDMA chaining feature in drivers of STM32 peripheral having request lines on STM32 DMA.

2019-07-15docs: arm: convert docs to ReST and rename to *.rstMauro Carvalho Chehab6-24/+9
Converts ARM the text files to ReST, preparing them to be an architecture book. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

2018-03-05ARM: stm32: add initial support for STM32MP157Ludovic Barre1-0/+19
This patch adds initial support of STM32MP157 microprocessor (MPU) based on Arm Cortex-A7. New Cortex-A infrastructure (gic, timer,...) are selected if ARCH_MULTI_V7 is defined. Signed-off-by: Ludovic Barre <ludovic.barre@st.com> Signed-off-by: Alexandre Torgue <alexandre.torgue@st.com>
2018-03-05ARM: stm32: prepare stm32 family to welcome armv7 architectureLudovic Barre1-6/+9
This patch prepares the STM32 machine for the integration of Cortex-A based microprocessor (MPU), on top of the existing Cortex-M microcontroller family (MCU). Since both MCUs and MPUs are sharing common hardware blocks we can keep using ARCH_STM32 flag for most of them. If a hardware block is specific to one family we can use either ARM_SINGLE_ARMV7M or ARCH_MULTI_V7 flag.
