Hi everyone, This is v2 of the initial Allwinner A80 support series. 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 options to use UART0 on the A80 as the debug port for earlyprintk. Patch 3 adds a barebone dtsi with just the cpu, memory and uart nodes. Patch 4 adds a barebone dts for the A80 Optimus Board. Patch 5 documents the vendor prefix for Merrii Technology Co., Ltd, the designer and vendor of the A80 Optimus Board. Patch 6 documents all the Allwinner SoCs we currently support. Patch 7 updates the sunxi README with a link to the A80's datasheet. 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 (7): ARM: sunxi: Introduce Allwinner A80 support ARM: sunxi: Add debug uart used by sun9i (Allwinner A80) ARM: dts: sunxi: Add Allwinner A80 dtsi ARM: dts: sun9i: Add A80 Optimus Board support devicetree: bindings: Add vendor prefix for Merrii Technology Co., Ltd. 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 + .../devicetree/bindings/vendor-prefixes.txt | 1 + arch/arm/Kconfig.debug | 10 + arch/arm/boot/dts/Makefile | 2 + arch/arm/boot/dts/sun9i-a80-optimus.dts | 66 +++++ arch/arm/boot/dts/sun9i-a80.dtsi | 287 +++++++++++++++++++++ arch/arm/mach-sunxi/Kconfig | 5 + arch/arm/mach-sunxi/sunxi.c | 9 + 9 files changed, 394 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 -- 2.1.0 -- 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
