to implement device tree concept in ARM linux krnl

[sjremya]

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?
