Subject: [PATCH v2 04/10] arm64: introduce STM32 family on Armv8 architecture
Date: Fri, 2 Jun 2023 15:28:53 +0200	[thread overview]
Message-ID: <20230602132859.16442-5-alexandre.torgue@foss.st.com> (raw)
In-Reply-To: <20230602132859.16442-1-alexandre.torgue@foss.st.com>

Add a dedicated ARCH_STM32 for STM32 SoCs config. First STM32 Armv8 SoC
family is the STM32MP25 which is composed of STM32MP251, STM32MP253,
STM32MP255, STM32MP257 SoCs.
