From 4e9b6041bbdddde93369df47ba44c759e29c0972 Mon Sep 17 00:00:00 2001 From: Mukesh Ojha Date: Thu, 25 Jun 2026 00:38:27 +0530 Subject: [PATCH] arm64: dts: qcom: sm6350: Add minidump SRAM config to SCM node Point the SCM node at the minidump config slot in the always-on SRAM. Boot firmware reads this word before DDR is initialised on a warm reset to decide where to deliver the minidump.
