Hi Marek,

I have not sent in this patch set the update of the device tree files.
Currently, for backward compatibility, the FMC2 is only supported the 
NAND driver. We need to wait the review of the different maintainers 
before updating the device tree files (bindings acked, ...).
I will send a DT file update for your own test.

Christophe Kerello.
