Hi all -This patch serie hasn't goal to create a platform with asymmetric linux processor (like vf610). -Today, STM32 family have several boards with mcu microcontroler Cortex-M like stm32f429, stm32f746... And this patch serie prepare new board with support of Cortex-A instead-of Cortex-M. (tha

[PATCH 1/6] ARM: stm32: prepare stm32 family to welcome armv7 architecture

2017-12-08 Thread Ludovic Barre
From: Ludovic Barre 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
