[PATCH v5] arm64: dts: qcom: sm8650: Add minidump SRAM config to SCM node
From: Mukesh Ojha
Date: Wed Aug 05 2026 - 09:47:51 EST
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.
