Thanks a lot for taking time to rearrange your board description to
Device Tree!

I think that this board name is a little bit too short.

Moreover, if it is a board by itself, I would have expected a *.dts
file. Otherwise you will not be able to generate a .dtb out of it...

As it is based on Telit board, maybe you can take advantage of their own
board as a common base? Am I wrong?

Thanks for submitting this work, it has to be amended but it seems on
the good way.
