From dc2ec80bc949d3fdb4b4c6b848e7e25a2758272f Mon Sep 17 00:00:00 2001 From: William Zhang Date: Fri, 8 Jul 2022 11:25:07 -0700 Subject: [PATCH] arm64: dts: broadcom: bcm4908: Fix cpu node for smp boot [ Upstream commit 8bd582ae9a71d7f14c4e0c735b2eacaf7516d626 ] 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.
