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 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 (5): misc: sram: add ability to limit used sram areas 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 | 24 +++ 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 | 195 ++++++++++++++++++++ arch/arm/mach-rockchip/rockchip.c | 2 + drivers/misc/sram.c | 51 ++++- 13 files changed, 368 insertions(+), 6 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
