Date: Wed, 15 Jan 2014 22:40:02 +0100 From: Heiko Stübner <heiko@...ech.de> To: "linux-arm-kernel@...ts.infradead.org" <linux-arm-kernel@...ts.infradead.org> Cc: arm@...nel.org, Grant Likely <grant.likely@...aro.org>, Rob Herring <robherring2@...il.com>, devicetree@...r.kernel.org, Philipp Zabel <p.zabel@...gutronix.de>, linux-kernel@...r.kernel.org, Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Pawel Moll <pawel.moll@....com>, Mark Rutland <mark.rutland@....com>, Stephen Warren <swarren@...dotorg.org>, Ian Campbell <ijc+devicetree@...lion.org.uk> Subject: [PATCH v6 0/6] ARM: rockchip: add smp functionality This series enables the use of the additional cores on Rockchip Cortex-A9 SoCs. To achieve this, add the scu, the needed sram and power-management-unit. Tested on both a BQ Curie2 (rk3066a / dual core) and on a Radxa Rock (rk3188 / quad core). changes since v5: - Grant Likely liked it better to "specify reserved regions of the memory instead of the valid ranges", so go back to the mmio-sram-reserved property originally suggested by Rob Herring changes since v4: - rebase on top of the recent rk3188 board support - implement suggestion from Matt Sealey in moving the sram-limit from marking reserved regions to marking available regions - hopefully I got the usage right - remove __CPUINIT as suggested by Fabio Estevam changes since v3: - address comments from Rob Herring: - split the gathering of the reserve-data into a separate loop - spelling and style fixes - first patch only included for reference, already part of the char-misc git tree changes since v2: - rework the sram allocation following the suggestion from Philipp Zabel changes since v1: - add reserved block feature for mmio-sram, to not use two logical sram nodes - the sram content is kept intact while the device is running, so copying the trampoline is only needed once Heiko Stuebner (6): dt-bindings: sram: describe option to reserve parts of the memory misc: sram: implement mmio-sram-reserved option ARM: rockchip: add snoop-control-unit ARM: rockchip: add sram dt nodes and documentation ARM: rockchip: add power-management-unit ARM: rockchip: add smp bringup code .../devicetree/bindings/arm/rockchip/pmu.txt | 16 ++ .../devicetree/bindings/arm/rockchip/smp-sram.txt | 23 +++ Documentation/devicetree/bindings/misc/sram.txt | 8 + arch/arm/boot/dts/rk3066a.dtsi | 6 + arch/arm/boot/dts/rk3188.dtsi | 6 + arch/arm/boot/dts/rk3xxx.dtsi | 10 + arch/arm/mach-rockchip/Kconfig | 1 + arch/arm/mach-rockchip/Makefile | 1 + arch/arm/mach-rockchip/core.h | 22 +++ arch/arm/mach-rockchip/headsmp.S | 30 +++ arch/arm/mach-rockchip/platsmp.c | 208 ++++++++++++++++++++ arch/arm/mach-rockchip/rockchip.c | 2 + drivers/misc/sram.c | 118 ++++++++++- 13 files changed, 443 insertions(+), 8 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/rockchip/pmu.txt create mode 100644 Documentation/devicetree/bindings/arm/rockchip/smp-sram.txt create mode 100644 arch/arm/mach-rockchip/core.h create mode 100644 arch/arm/mach-rockchip/headsmp.S create mode 100644 arch/arm/mach-rockchip/platsmp.c -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
