cpu_is_at91xx have been removed from the kernel, using the correct
compatible should be enough, see

Thanks for you information. Missing this patch, check the next-20150209, it is here. I will base on next-20150209, so this patch no need anymore, only need to change the dts(i) file now.

Thanks again.
