[opensuse-arm] Build a downstream kernel in OBS

Hi, Is there a guide on how to build a downstream kernel in obs like a upstream genuine kernel? I have a CHIP allwinner R8 with debian but I would like to use opensuse instead. I found a link in the wiki to a script which is supposed to help with this (http://users.suse.com/~dmueller/contrib_kernel.sh) but like is dead to me. Thanks! -- Cheers
