arm: at91: Add new board
PATCH 1/1 arm: at91: Add new board
I'd like to add support for our "CDU" board based up on Telit's module GE863 Pro3. It has more uarts, leds, another nand partitioning.

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.
Best regards,
