    to implement device tree concept in ARM linux krnl


    hi all


    POWERPC linux kernel has a device tree, to configure the external peripherals connected to the processor. It is in the path

    arch/powerpc/boot/dts/***.dts


    But ARM linux kernel does not have DEVICE TREE. Then how the external peripherals configuration is implemented in ARM linux kernel ? And if we need to add a new device, where we need to modify. Any idea ??

    Please help me out


    Thanks in advance

    For arm we have device files as *.c files like at91sam9260_devices.c. You can find these files in arch/arm/mach-at91/. Which processor are you using?
