From 7b09167cb7cb09282200903b6371996df4d76bc4 Mon Sep 17 00:00:00 2001 From: Beleswar Padhi Date: Mon, 8 Sep 2025 19:57:53 +0530 Subject: [PATCH] arm64: dts: ti: k3-j7200: Enable R5F remote processors at board level Remote Processors defined in top-level J7200 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.
