Subject: [PATCH v5 4/7] ARM: stm32: add initial support for STM32MP157
Date: Tue, 16 Jan 2018 15:56:17 +0100	[thread overview]
Message-ID: <1516114580-2424-5-git-send-email-ludovic.Barre@st.com> (raw)
In-Reply-To: <1516114580-2424-1-git-send-email-ludovic.Barre@st.com>

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

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.
