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


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
