This series add SMP brinup support for mediatek SoCs. This is based on v4.1-rc1. There are 2 similar but different SMP bringup up methods on Mediatek mt65xx and mt81xx. On MT8135 & MT8127, system boots with a trustzone firmware. Others, like MT6589, doesn't have trustzone, and run kernel directly in secure world. Patch 1,2 are preparing patch, cleanup/fix in secondary_startup_arm Patch 3~5 fix issues in mtk_timer(GPT) and enable arch timer support. Patch 6,7 add support for cpu enable-method "mediatek,mt65xx-smp" and "mediatek,mt81xx-tz-smp", which support Mediatek SMP bringup for non-TZ and TZ platform. Patch 8,9 finally enable SMP bringup for mt8135 and mt8127. Changes in v2: - Fix boot issue for THUMB2 kernel. - Not enable GPT_CLK_EVT when setup to fix GPT spurious interrupt issue - Change platsmp.c according to Matthias' suggestion v1: http://lists.infradead.org/pipermail/linux-mediatek/2015-May/000528.html Matthias Brugger (1): ARM: mediatek: enable gpt6 on boot up to make arch timer working Yingjoe Chen (8): ARM: correct secondary_startup_arm mode ARM: add secondary_startup_arm prototype in header file clocksource: mediatek: do not enable GPT_CLK_EVT when setup clocksource: mediatek: Use GPT as sched clock source devicetree: bindings: add new SMP enable method Mediatek SoC ARM: mediatek: add smp bringup code ARM: dts: mt8135: enable basic SMP bringup for mt8135 ARM: dts: mt8127: enable basic SMP bringup for mt8127 Documentation/devicetree/bindings/arm/cpus.txt | 2 + arch/arm/boot/dts/mt8127.dtsi | 16 +++ arch/arm/boot/dts/mt8135.dtsi | 16 +++ arch/arm/include/asm/smp.h | 1 + arch/arm/kernel/head.S | 2 +- arch/arm/mach-mediatek/Makefile | 3 + arch/arm/mach-mediatek/mediatek.c | 29 +++++ arch/arm/mach-mediatek/platsmp.c | 144 +++++++++++++++++++++++++ drivers/clocksource/mtk_timer.c | 25 ++++- 9 files changed, 232 insertions(+), 6 deletions(-) create mode 100644 arch/arm/mach-mediatek/platsmp.c -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
