I tested this and it works on my device, it is also in OpenWrt now: https://dev.openwrt.org/browser/trunk/target/linux/bcm53xx/patches-4.1/131-ARM-BCM-Add-SMP-support-for-Broadcom-4708.patch?rev=47247 > > Signed-off-by: Jon Mason <[email protected]> > --- > arch/arm/boot/dts/bcm4708.dtsi | 2 ++ > arch/arm/boot/dts/bcm94708.dts | 2 +- > arch/arm/mach-bcm/Kconfig | 1 + > arch/arm/mach-bcm/Makefile | 3 +++ > 4 files changed, 7 insertions(+), 1 deletion(-) > > diff --git a/arch/arm/boot/dts/bcm4708.dtsi b/arch/arm/boot/dts/bcm4708.dtsi > index 31141e8..22a41df 100644 > --- a/arch/arm/boot/dts/bcm4708.dtsi > +++ b/arch/arm/boot/dts/bcm4708.dtsi > @@ -15,6 +15,8 @@ > cpus { > #address-cells = <1>; > #size-cells = <0>; > + enable-method = "brcm,bcm-nsp-smp"; > + secondary-boot-reg = <0xffff0400>; > > cpu@0 { > device_type = "cpu"; > diff --git a/arch/arm/boot/dts/bcm94708.dts b/arch/arm/boot/dts/bcm94708.dts > index f60bb1d..49682d6 100644 > --- a/arch/arm/boot/dts/bcm94708.dts > +++ b/arch/arm/boot/dts/bcm94708.dts > @@ -32,7 +32,7 @@ > > /dts-v1/; > > -#include "bcm5301x.dtsi" > +#include "bcm4708.dtsi" This is already changed in the patch adding this file. > > / { > model = "NorthStar SVK (BCM94708)"; > diff --git a/arch/arm/mach-bcm/Kconfig b/arch/arm/mach-bcm/Kconfig > index 2e9dbb5..4fc8fa3 100644 > --- a/arch/arm/mach-bcm/Kconfig > +++ b/arch/arm/mach-bcm/Kconfig > @@ -54,6 +54,7 @@ config ARCH_BCM_NSP > config ARCH_BCM_5301X > bool "Broadcom BCM470X / BCM5301X ARM SoC" if ARCH_MULTI_V7 > select ARCH_BCM_IPROC > + select HAVE_SMP probably this is also needed: select ARM_ERRATA_764369 if SMP The CPU should be affected by this issue. > help > Support for Broadcom BCM470X and BCM5301X SoCs with ARM CPU cores. > > diff --git a/arch/arm/mach-bcm/Makefile b/arch/arm/mach-bcm/Makefile > index 36a4ca30..3ca1cf1 100644 > --- a/arch/arm/mach-bcm/Makefile > +++ b/arch/arm/mach-bcm/Makefile > @@ -43,6 +43,9 @@ obj-$(CONFIG_ARCH_BCM2835) += board_bcm2835.o > > # BCM5301X > obj-$(CONFIG_ARCH_BCM_5301X) += bcm_5301x.o > +ifeq ($(CONFIG_ARCH_BCM_5301X),y) > +obj-$(CONFIG_SMP) += headsmp.o platsmp.o > +endif > > # BCM63XXx > ifeq ($(CONFIG_ARCH_BCM_63XX),y) > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
