Looking for Device Tree file for Beaglebone (White) and 3.8 Kernel optimized for Beaglebone


I am having Beaglebone white board which contains AM3359 Processor. I wanted to load the latest 3.8 kernel with device tree on that board. Is there any one tried that? If so can you please post the device tree file for AM3359. Also the link to latest Linux 3.8 kernel optimized for Beaglebone.

Thank you,
