Subject: [PATCH] arm64: dts: arm: Add stdout-path
Date: Tue, 30 Jul 2024 11:37:58 +0100 [thread overview]
Message-ID: <20240730103758.907950-1-Debbie.Martin@arm.com> (raw)
Add stdout-path to the Arm devicetrees to specify the primary console.
This means that distributions can boot without the need for
platform-specific command line parameters i.e. they can use earlycon
with no parameters and no console argument is needed at all.
