All told, the 4th patch adds less than 950 lines of code to the kernel, which is pretty darn good for a whole new subarch. The zynq platform is a pretty ideal test case for this since the goal has been from day one to depend on CONFIG_OF. The previous series only used static device registrations because device tree on arm isn't yet in mainline. Plus, xilinx is already quite comfortable with how to use the device tree since their other two architectures (powerpc and microblaze) have depended on device tree for years now. I'd like to get your thoughts on the reuse of plat-versatile for the struct clk implementation. I'm certainly not excited about creating yet another implementation, and versatile seems to be ideal to reuse. The previous version of this board support has already been in linux-next for quite a while now. If you do decide to pick up device tree support for 2.6.40, then it would pretty low risk thing to queue up this board support also. The 2nd and 3rd patches aren't actually part of the board support, but I included them here because they're needed to get the patch to apply. The whole series is based on top of both the irq_domain series I posted last week and the latest arm device tree support series. g. --- Grant Likely (4): arm/dt: Add dt machine definition of/address: Add of_find_matching_node_by_address helper dt/irq: add of_irq_domain_add_simple() helper ARM: Xilinx: Adding Xilinx board support Documentation/devicetree/bindings/arm/xilinx.txt | 7 + arch/arm/Kconfig | 14 + arch/arm/Makefile | 2 arch/arm/boot/dts/zynq-ep107.dts | 52 ++++ arch/arm/include/asm/mach/arch.h | 9 + arch/arm/mach-zynq/Makefile | 6 arch/arm/mach-zynq/Makefile.boot | 3 arch/arm/mach-zynq/board_dt.c | 36 +++ arch/arm/mach-zynq/common.c | 112 ++++++++ arch/arm/mach-zynq/common.h | 29 ++ arch/arm/mach-zynq/include/mach/clkdev.h | 32 ++ arch/arm/mach-zynq/include/mach/debug-macro.S | 36 +++ arch/arm/mach-zynq/include/mach/entry-macro.S | 30 ++ arch/arm/mach-zynq/include/mach/hardware.h | 18 + arch/arm/mach-zynq/include/mach/io.h | 33 ++ arch/arm/mach-zynq/include/mach/irqs.h | 21 ++ arch/arm/mach-zynq/include/mach/memory.h | 22 ++ arch/arm/mach-zynq/include/mach/system.h | 28 ++ arch/arm/mach-zynq/include/mach/timex.h | 23 ++ arch/arm/mach-zynq/include/mach/uart.h | 25 ++ arch/arm/mach-zynq/include/mach/uncompress.h | 51 ++++ arch/arm/mach-zynq/include/mach/vmalloc.h | 20 + arch/arm/mach-zynq/include/mach/zynq_soc.h | 48 ++++ arch/arm/mach-zynq/timer.c | 298 ++++++++++++++++++++++ arch/arm/mm/Kconfig | 2 drivers/of/address.c | 18 + drivers/of/irq.c | 44 +++ include/linux/of_address.h | 4 include/linux/of_irq.h | 2 29 files changed, 1024 insertions(+), 1 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/xilinx.txt create mode 100644 arch/arm/boot/dts/zynq-ep107.dts create mode 100644 arch/arm/mach-zynq/Makefile create mode 100644 arch/arm/mach-zynq/Makefile.boot create mode 100644 arch/arm/mach-zynq/board_dt.c create mode 100644 arch/arm/mach-zynq/common.c create mode 100644 arch/arm/mach-zynq/common.h create mode 100644 arch/arm/mach-zynq/include/mach/clkdev.h create mode 100644 arch/arm/mach-zynq/include/mach/debug-macro.S create mode 100644 arch/arm/mach-zynq/include/mach/entry-macro.S create mode 100644 arch/arm/mach-zynq/include/mach/hardware.h create mode 100644 arch/arm/mach-zynq/include/mach/io.h create mode 100644 arch/arm/mach-zynq/include/mach/irqs.h create mode 100644 arch/arm/mach-zynq/include/mach/memory.h create mode 100644 arch/arm/mach-zynq/include/mach/system.h create mode 100644 arch/arm/mach-zynq/include/mach/timex.h create mode 100644 arch/arm/mach-zynq/include/mach/uart.h create mode 100644 arch/arm/mach-zynq/include/mach/uncompress.h create mode 100644 arch/arm/mach-zynq/include/mach/vmalloc.h create mode 100644 arch/arm/mach-zynq/include/mach/zynq_soc.h create mode 100644 arch/arm/mach-zynq/timer.c -- Signature -- 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/
