Subject: [PATCH v3 02/33] arm64: dts: ti: k3-j721e: Enable remote processors at board level
Date: Fri, 5 Sep 2025 10:48:15 +0530 [thread overview]
Message-ID: <20250905051846.1189612-3-b-padhi@ti.com> (raw)
In-Reply-To: <20250905051846.1189612-1-b-padhi@ti.com>
Remote Processors defined in top-level J721E SoC dtsi files are
incomplete without the memory carveouts and mailbox assignments
which are only known at board integration level.
Therefore, disable the remote processors at SoC level and enable
them at board level where above information is available.
