This patch series adds very basic support for Allwinner's A80 SoC, a big.LITTLE architecture with 4 Cortex-A7s and 4 Cortex-A15s. Development is done on the A80 Optimus Board, the defacto development board for the A80, with the accompanying SDK as a reference. So far I've been unable to get the board to boot from MMC, or using Android fastboot. I'm using Allwinner's FEL mode to load the bootloader and kernel+dtb image over USB. Notes on my attempts can be found here: http://linux-sunxi.org/User:Wens#A80_Optimus Patch 1 introduces the compatible string for the A80. Patch 2 adds a barebone dtsi with just the cpu, memory and uart nodes. Patch 3 adds a barebone dts for the A80 Optimus Board. Patch 4 documents all the Allwinner SoCs we currently support. Patch 5 updates the sunxi README with a link to the A80's datasheet. Changes since v2: - Dropped (unused) cpu topology map from dtsi - Added comment on ranges usage in dtsi - Corrected typo in bindings document - Dropped "A80" from Kconfig sun9i machine label and DT machine description - Dropped 2 patches already queued: ARM: sunxi: Add debug uart used by sun9i (Allwinner A80) devicetree: bindings: Add vendor prefix for Merrii Technology Co., Ltd. Changes since v1: - Use skeleton64.dtsi as basis to support maximum of 8GB DRAM - Dropped dependency on ARCH_SUNXI for DEBUG_SUN9I_UART0 - Added empty lines separating cores in the DT cpu-map node - Added patch 7 to update sunxi README Cheers ChenYu Chen-Yu Tsai (5): ARM: sunxi: Introduce Allwinner A80 support ARM: dts: sunxi: Add Allwinner A80 dtsi ARM: dts: sun9i: Add A80 Optimus Board support devicetree: bindings: Document supported Allwinner sunxi SoCs Documentation: sunxi: Add A80 datasheet link Documentation/arm/sunxi/README | 3 +- Documentation/devicetree/bindings/arm/sunxi.txt | 12 ++ arch/arm/boot/dts/Makefile | 2 + arch/arm/boot/dts/sun9i-a80-optimus.dts | 66 ++++++ arch/arm/boot/dts/sun9i-a80.dtsi | 257 ++++++++++++++++++++++++ arch/arm/mach-sunxi/Kconfig | 5 + arch/arm/mach-sunxi/sunxi.c | 9 + 7 files changed, 353 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/arm/sunxi.txt create mode 100644 arch/arm/boot/dts/sun9i-a80-optimus.dts create mode 100644 arch/arm/boot/dts/sun9i-a80.dtsi -- 2.1.1 -- 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/
