to implement device tree concept in ARM linux krnel
 
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

I'm thinking the POWERPC linux kernel has been compiled with different options than the one in ARM linux.
If you have a "/proc/config.gz" file, can you pull one from the POWERPC linux and from the ARM linux, then compare the two?

That might help!

P.S: I've "Thanked" you post, because it made me smile. I *love* PowerPC!!
