Rock 5 B Opensuse Tumbleweed

Does anyone have been successfull installing Tumbleweed ?
Is there an howto?
Waiting for my Rock 5 and want to be prepared to get it working.

If you want to install from iso, there are several steps:
1, Prepare uefi image for rock5b. There is already the source code of uefi in the sdk from rockchip:
2, Prepare an tumbleed iso which supports rock5b. I don’t know much about how opensuse iso is generated, but at least you need a bootable kernel for rock5b.

Is there any precompiled binary available ?
