| 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") |
