What I miss in at91sam9261_devices.c (as compared to the 9260)
is support for MACB and MCI. Don't 9261 systems use Ethernet?
Or is that part still in the board specific files?
Then, I would like to add the following changes:

I have this as a local patch and could squash this onto yours, or
you may provide an updated patch.
