The Calao USB A9263 board is a board manufactured and sold by Calao
Systems <http://www.calao-systems.com>. Its components are very
similar to the AT91SAM9263EK board, so its configuration is based
on the configuration of this board. There are however some

Comments

Dear Thomas Petazzoni,

I can find no comments or anything for this patch.

Please change this to use boards.cfg instead.

Not sure, but I think Copyright should be in newest date at the top...

Someone complained earlier in a similiar case that #undefs are not allowed
here, convert this into a comment _IF_ your board can use other USARTs for
console at all. If not drop the #undef lines.

If you would like this patch to go mainstream, please resubmit it and
make sure it will apply to current top-of-tree
.

Best Regards
Reinhard
