It would be good if you can elaborate the commit log, maybe use this
as an oportunity to point URLs to the product page or the
documentation.

You can use [1] as example if you feel like.

Please, split this commit in 3: One for u-boot, one for kernel, one for machine

kernel 3.10.17 is not compatible with the Vivante version in master.
Please, upgrade it at least to 3.10.53

Please, add a DESCRIPTION with more information about why one need a
fork to use your board, and where the fork is from, and I would also
include which Advantech board this kernel support, if it's only one
today, when you upgrade you can include the others.

Please, use a LOCALVERSION that make sense to you and your users. I
mean, what is the version of this fork, not the version this kernel
was forked from.

Is there a plan to have more imx6 Advantech's boards in future?
