Subject: [PATCH v4 1/2] ARM: dts: stm32: Update Cortex-M4 reset declarations on stm32mp15
Date: Wed, 17 May 2023 09:48:29 +0200	[thread overview]
Message-ID: <20230517074830.569398-2-arnaud.pouliquen@foss.st.com> (raw)
In-Reply-To: <20230517074830.569398-1-arnaud.pouliquen@foss.st.com>

Since the introduction of the SCMI for the management
of the MCU hold boot in OP-TEE, management of the hold boot by SMC call
is deprecated.
- Clean the st,syscfg-tz  which allows to determine if the trust
zone is enable.
- Add reset-names properties to be able to differentiate the MCU reset and
  the MCU HOLD BOOT.
