implementing 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
