This is v4 and is based on v4.3-rc1. There are 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 enable arch timer support. Patch 2,3 add support for cpu enable-method "mediatek,mt6589-smp" and "mediatek,mt81xx-tz-smp", which support Mediatek SMP bringup for non-TZ and TZ platform. Patch 4,5 finally enable SMP bringup for mt8135 and mt8127. Changes in v4: - rebase to v4.3-rc1 - Reserve trustzone bootinfo memory area in device tree. Changes in v3: - v3 in [1] - The first 2 patches in v2 are merged in v4.2-rc1. - Patch 3~4 in v2 are moved to another series [2] - platsmp.c changes based on Stephen's suggestion - Change cpu enable-method name to "mediatek,mt6589-smp" 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 http://lists.infradead.org/pipermail/linux-mediatek/2015-May/000714.html v1: http://lists.infradead.org/pipermail/linux-mediatek/2015-May/000528.html [1] http://lists.infradead.org/pipermail/linux-mediatek/2015-July/001570.html [2] http://lists.infradead.org/pipermail/linux-mediatek/2015-July/001544.html Matthias Brugger (1): ARM: mediatek: enable gpt6 on boot up to make arch timer working Yingjoe Chen (4): 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 | 27 +++++ arch/arm/boot/dts/mt8135.dtsi | 27 +++++ arch/arm/mach-mediatek/Makefile | 3 + arch/arm/mach-mediatek/mediatek.c | 27 +++++ arch/arm/mach-mediatek/platsmp.c | 141 +++++++++++++++++++++++++ 6 files changed, 227 insertions(+) create mode 100644 arch/arm/mach-mediatek/platsmp.c -- 1.9.1
