Fourth posting. v4 rebases on top of Nicolas' patch to merge lookup_machine_type() into setup_machine(). It also adds documentation and error output when the kernel cannot find a machine_desc that matches the top level compatible property. I'm not asking for these patches to be merged into mainline yet, but I'm fairly confident that they should be pretty close to their final form. Not included in this series is: - Russell's patch to remove early vetting of the machine type number - Rob's patch to map the region if atags or the dtb are not within the first 1MB of ram. - Nicolas' patch to eliminate lookup_machine_type() However, I am carrying those patches in my devicetree/arm and devicetree/test branches for anyone who wants to try them out. Please test. ... This patch series allows CONFIG_OF to be enabled on ARM and allows the kernel to accept a dtb pointer from boot firmware instead of atags. If a dtb is passed, then the kernel will use the root 'compatible' property to find a matching machine_desc, and it will use it to obtain the memory layout, initrd location and kernel parameters string. Only limited device tree support is enabled here. It does not perform any kind of device registration from device tree data. That support will be enabled in a later patch set. Rather, this series is a stable base that other engineers can use to start working on device tree support for their platforms. Tested on Versatile (qemu) and nVidia Tegra Harmony. Kernel compiles and boots with CONFIG_OF both on and off, both with and without passing a device tree blob. This series is reflected in the following branch (stable; will not be rebased): git://git.secretlab.ca/git/linux-2.6 devicetree/arm The 'clean' patches (rebased) can be found here: git://git.secretlab.ca/git/linux-2.6 devicetree/test --- Grant Likely (6): arm/dt: Make __vet_atags also accept a dtb image arm/dt: consolidate atags setup into setup_machine_atags arm/dt: probe for platforms via the device tree arm/dt: Basic versatile devicetree support arm/dt: Basic tegra devicetree support dt: add documentation of ARM dt boot interface Jeremy Kerr (1): arm/dt: Allow CONFIG_OF on ARM Documentation/arm/Booting | 33 +++++ Documentation/devicetree/booting-without-of.txt | 40 ++++++ arch/arm/Kconfig | 7 + arch/arm/include/asm/mach/arch.h | 9 + arch/arm/include/asm/prom.h | 37 ++++++ arch/arm/include/asm/setup.h | 5 + arch/arm/kernel/Makefile | 1 arch/arm/kernel/devtree.c | 147 +++++++++++++++++++++++ arch/arm/kernel/head-common.S | 24 +++- arch/arm/kernel/head.S | 8 + arch/arm/kernel/setup.c | 86 ++++++++----- arch/arm/mach-tegra/board-harmony.c | 6 + arch/arm/mach-versatile/versatile_ab.c | 6 + arch/arm/mach-versatile/versatile_pb.c | 6 + arch/arm/mm/init.c | 11 ++ 15 files changed, 379 insertions(+), 47 deletions(-) create mode 100644 arch/arm/include/asm/prom.h create mode 100644 arch/arm/kernel/devtree.c -- Signature -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to email@example.com More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
