From a1db65c7980a5567396a74ce94272d26f0bcb86a Mon Sep 17 00:00:00 2001 From: Mukesh Ojha Date: Thu, 25 Jun 2026 00:38:22 +0530 Subject: [PATCH] arm64: dts: qcom: sm8550: 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.
