This is based on v4.2-rc1 and Matthias' next branch (for dts parts). 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 v3: - The first 2 patches in v2 are merged in v4.2-rc1. - Patch 3~4 in v2 are moved to another series [1] - 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/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 | 16 +++ arch/arm/boot/dts/mt8135.dtsi | 16 +++ arch/arm/mach-mediatek/Makefile | 3 + arch/arm/mach-mediatek/mediatek.c | 27 +++++ arch/arm/mach-mediatek/platsmp.c | 144 +++++++++++++++++++++++++ 6 files changed, 208 insertions(+) create mode 100644 arch/arm/mach-mediatek/platsmp.c From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yingjoe Chen Subject: [PATCH v3 0/5] Add SMP bringup support for mt65xx socs Date: Tue, 14 Jul 2015 13:18:26 +0800 Message-ID: <1436851111-2369-1-git-send-email-yingjoe.chen@mediatek.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Matthias Brugger Cc: Russell King , devicetree@vger.kernel.org, Arnd Bergmann , Stephen Boyd , linux-kernel@vger.kernel.org, Rob Herring , linux-mediatek@lists.infradead.org, Sascha Hauer , Olof Johansson , Yingjoe Chen , srv_heupstream@mediatek.com, linux-arm-kernel@lists.infradead.org List-Id: linux-mediatek@lists.infradead.org This series add SMP brinup support for MediaTek SoCs.
