The device tree is passed by the bootloader via setup_data. It is used as an additional source of information and does not replace the "traditional" x86 boot page. Right now we get the the following information from it: - hpet location - apic & ioapic location - ioapic's interrupt routing - legacy devices which are not initialized by bios - devices which are behind a bus which does not support enumeration like i2c The series is based on the tip tree and is also available at git://git.linutronix.de/users/bigeasy/soda.git ce_of Sebastian Andrzej Siewior (11): x86/kernel: remove conditional early remap in parse_e820_ext x86: Add device tree support x86/dtb: Add a device tree for CE4100 x86/dtb: add irq host abstraction x86/dtb: add early parsing of APIC and IO APIC x86/dtb: add support hpet x86/dtb: add support for PCI devices backed by dtb nodes x86/dtb: Add generic bus probe x86/ioapic: Add OF bindings for IO-APIC x86/io_apic: add simply id set x86/ce4100: use OF for ioapic Documentation/x86/boot_with_dtb.txt | 20 ++ arch/x86/Kconfig | 7 + arch/x86/include/asm/bootparam.h | 1 + arch/x86/include/asm/e820.h | 2 +- arch/x86/include/asm/io_apic.h | 8 + arch/x86/include/asm/irq_controller.h | 12 + arch/x86/include/asm/prom.h | 67 ++++++ arch/x86/kernel/Makefile | 1 + arch/x86/kernel/apic/io_apic.c | 144 +++++++++++++ arch/x86/kernel/e820.c | 8 +- arch/x86/kernel/irqinit.c | 9 +- arch/x86/kernel/prom.c | 370 +++++++++++++++++++++++++++++++++ arch/x86/kernel/setup.c | 15 ++- arch/x86/platform/ce4100/ce4100.c | 16 ++- arch/x86/platform/ce4100/ce4100.dts | 210 +++++++++++++++++++ 15 files changed, 877 insertions(+), 13 deletions(-) create mode 100644 Documentation/x86/boot_with_dtb.txt create mode 100644 arch/x86/include/asm/irq_controller.h create mode 100644 arch/x86/include/asm/prom.h create mode 100644 arch/x86/kernel/prom.c create mode 100644 arch/x86/platform/ce4100/ce4100.dts Sebastian -- 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/
