From e030c56e38fcd5d30fb57f0db3388d13e29872b4 Mon Sep 17 00:00:00 2001 From: Mukesh Ojha Date: Thu, 25 Jun 2026 00:38:25 +0530 Subject: [PATCH] arm64: dts: qcom: sm8350: 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.
