- add new arch stm32mp for STM32 MPU/Soc based on Cortex A - support for stm32mp157 SOC - SPL is used as first boot stage loader - using driver model for all the drivers, even in SPL - all security feature are deactivated (ETZC and TZC) - reused STM32 MCU drivers when it is possible Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
