It uses CPU_METHOD_OF_DECLARE() (or rather a new variant of that) so that SMP operations are assigned using device tree rather than adding it to a machine definition in a board file. The first patch adds the ability to extract information from device tree nodes having a matching "enable-method" value. This allows additional parameters to be associated with the enable method. This is used for the Broadcom SoCs to efficiently determine the location of a special register used in coordinating the start of secondary CPUs. I have not included a device tree document update here; I would like suggestions on where the new enable method and its parameter should be documented. (I presume in .../arm/cpus.txt, but that could get out of hand as more boards define new enable methods.) -Alex Note: This series is based on the current arm-soc/for-next branch: e98cd72 arm-soc: document samsung merges Plus one more recently-posted patch: http://permalink.gmane.org/gmane.linux.kernel/1677714 This series is available here: http://git.linaro.org/landing-teams/working/broadcom/kernel.git Branch review/bcm-smp Alex Elder (5): ARM: introduce CPU_METHOD_OF_DECLARE_SETUP() ARM: add SMP support for Broadcom mobile SoCs ARM: configs: enable SMP in bcm_defconfig ARM: dts: enable SMP support for bcm28155 ARM: dts: enable SMP support for bcm21664 arch/arm/boot/dts/bcm11351.dtsi | 19 ++++ arch/arm/boot/dts/bcm21664.dtsi | 19 ++++ arch/arm/configs/bcm_defconfig | 2 + arch/arm/include/asm/smp.h | 10 +- arch/arm/kernel/devtree.c | 31 +++++-- arch/arm/mach-bcm/Kconfig | 18 +++- arch/arm/mach-bcm/Makefile | 5 +- arch/arm/mach-bcm/platsmp.c | 194 +++++++++++++++++++++++++++++++++++++++ 8 files changed, 286 insertions(+), 12 deletions(-) create mode 100644 arch/arm/mach-bcm/platsmp.c -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
