Thanks a lot for your contribution, and sorry for the very, very slow
response time. I'll add below a few comments, generally fairly minor.
If you could fix them, and submit an updated version of your patch, it
would be very nice.

First, the commit title should be something like this:

	configs/friendlyarm_nanopi_duo: new defconfig

Also, the DEVELOPERS file should be updated to add an entry that
associates your name/email with the defconfig and board directory.

The indentation looks odd here.

Please use a tag or exact SHA1 so that the build is reproducible.

Here as well.

Other than that, looks good to me! Could you send an updated version?

Thanks a lot,
