[PATCH v5 0/7] ARM: stm32: add initial STM32MPU support

[PATCH v5 0/7] ARM: stm32: add initial STM32MPU support

[Ludovic Barre]

From: Ludovic Barre <ludovic.barre@st.com>

This patch series extends the existing STM32 microcontrollers (MCUs)
family to microprocessors (MPUs). The MPU platform (based on
Arm Cortex-A) is a continuation of the MCU one (based on Arm
Cortex-M) in that it shares a wide number of hardware blocks.

change v5:
-fix serial3 aliases by serial0
 
change v4:
-Add all available uarts in stm32mp157c
-Move uart aliases to board files

change v3:
-Remove bootargs
-Remove armv7m_restart and Share stm32_compat for mcu/mpu
-Modify stm32 kconfig with Arnd template
-Remove patch below (Linus W: Patch applied)
 devicetree: bindings: Document supported STM32 SoC family
 pinctrl: stm32: Add STM32MP157 MPU support

change V2:
-Add stm32 documentation in this serie to avoid merge conflict
thread: "https://patchwork.kernel.org/patch/10102573/";
-Split bindings (stm32.txt) to separate patches.
-Remove ARCH_STM32_MCU/MPU flags
-Adopt rst format for Documentation/arm/stm32 files

[PATCH v5 2/7] ARM: stm32: prepare stm32 family to welcome armv7 architecture

[Ludovic Barre]

From: Ludovic Barre <ludovic.barre@st.com>

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.

+STM32MP157 Overview
+===================
+
+Introduction
+------------
+
+The STM32MP157 is a Cortex-A MPU aimed at various applications.
+It features:
+
+- Dual core Cortex-A7 application core
+- 2D/3D image composition with GPU
+- Standard memories interface support
+- Standard connectivity, widely inherited from the STM32 MCU family
+- Comprehensive security support

[PATCH v5 7/7] ARM: dts: stm32: add initial support of stm32mp157c eval board

[Ludovic Barre]

From: Ludovic Barre <ludovic.barre@st.com>

Add support of stm32mp157c evaluation board (part number: STM32MP157C-EV1)
split in 2 elements:
-Daughter board (part number: STM32MP157C-ED1)
 which includes CPU, memory and power supply
-Mother board (part number: STM32MP157C-EM1)
 which includes external peripherals (like display, camera,...)
 and extension connectors.

The daughter board can run alone, this is why the device tree files
are split in two layers, for the complete evaluation board (ev1)
and for the daughter board alone (ed1).

I will merge stm32 DT patches and mach-stm32 patches in my next pull 
requests.
What about Documentation patch and multi-v7 config patch ?
(I could add Documentation patch in my DT pull request)
