From 091df90a89ecd2526c6ba401c1b55af6b77da95e Mon Sep 17 00:00:00 2001 From: Alice Guo Date: Thu, 20 Nov 2025 19:22:59 +0800 Subject: [PATCH] arm: dts: imx8ulp: Ensure mu@27020000 and lpuart5 availability during all boot phases mu@27020000 is required for communication with ELE firmware, and lpuart5 is the standard output device. Both peripherals must be available before U-Boot relocation. Use bootph-all instead of bootph-pre-ram so these nodes are retained across all boot phases.
