+Subject: [PATCH] arm64: dts: broadcom: bcm4908: Fix cpu node for smp boot
+
+Add spin-table enable-method and cpu-release-addr properties for
+cpu0 node. This is required by all ARMv8 SoC. Otherwise some
+bootloader like u-boot can not update cpu-release-addr and linux
+fails to start up secondary cpus.
+
+Fixes: 2961f69f151c ("arm64: dts: broadcom: add BCM4908 and Asus GT-AC5300 early DTS files")
