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")
