[PATCH v3 13/18] arm64: dts: qcom: sm8350: Add minidump SRAM config to SCM node
From: Mukesh Ojha
Date: Fri May 22 2026 - 16:02:50 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.
