4 Subject: [PATCH] arm64: dts: broadcom: bcm4908: Fix cpu node for smp boot
5
6 Add spin-table enable-method and cpu-release-addr properties for
7 cpu0 node. This is required by all ARMv8 SoC. Otherwise some
8 bootloader like u-boot can not update cpu-release-addr and linux
9 fails to start up secondary cpus.
