Actually I would prefer to get this right in one go, esp. the
filename bits, having u-boot and the kernel disagreeing on the
dtb filename is no good. So I plan to remove this version of
the patch from u-boot-sunxi/next for now. Once you and Maxime
agree on a dts / dtb filename please submit a new version and
I'll merge that one instead.

Regards,

Hans
