To achieve this, add the scu, the needed sram and power-management-unit. Tested on a rk3066a (dual core) by me and on a rk3188 (quad core) by Ulrich Prinz. (Note: rk3188 support in general needs additional upcoming patchsets) 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): misc: sram: fix error path in sram_probe misc: sram: add ability to mark sram sections as reserved ARM: rockchip: add snoop-control-unit ARM: rockchip: add sram dt nodes and documentation ARM: rockchip: add power-management-unit dt node 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 | 16 ++ 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 | 32 +++ arch/arm/mach-rockchip/platsmp.c | 203 ++++++++++++++++++++ arch/arm/mach-rockchip/rockchip.c | 2 + drivers/misc/sram.c | 100 +++++++++- 11 files changed, 417 insertions(+), 7 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@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
