This series adds the SMP support for Marvell Berlin BG2 and BG2Q. This implementation takes advantage of the reset exception register and the software reset address register to make the CPUs execute the Berlin secondary startup when being reset. This has the advantage of not using the pen lock mechanism. Patch 3 depends on Alex Elder effort to properly document CPU enable methods: https://patchwork.kernel.org/patch/4138211/ Changes since v1: - added a proper enable-method documentation - s/reseted/reset/ and s/register/vector/ - removed unneeded 'select SMP' Antoine Ténart (5): ARM: berlin: add SMP support Documentation: bindings: add the Berlin CPU control doc Documentation: bindings: add the marvell,berlin-smp CPU enable method ARM: dts: berlin: add SMP related nodes and properties for BG2 ARM: dts: berlin: add SMP related nodes and properties for BG2Q .../arm/cpu-enable-method/marvell,berlin-smp | 41 +++++++++ .../devicetree/bindings/arm/marvell,berlin.txt | 16 ++++ arch/arm/boot/dts/berlin2.dtsi | 11 +++ arch/arm/boot/dts/berlin2q.dtsi | 11 +++ arch/arm/mach-berlin/Kconfig | 3 + arch/arm/mach-berlin/Makefile | 3 +- arch/arm/mach-berlin/headsmp.S | 30 +++++++ arch/arm/mach-berlin/platsmp.c | 99 ++++++++++++++++++++++ 8 files changed, 213 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/arm/cpu-enable-method/marvell,berlin-smp create mode 100644 arch/arm/mach-berlin/headsmp.S create mode 100644 arch/arm/mach-berlin/platsmp.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
