Dear Wolfgang Denk,

Thank you for your quick response.

The above code section is used also in other ATMEL boards like
at91sam9260ek ( /board/atmel/at91sam9260ek/at91sam9260ek.c ),
at91sam9261ek, at91sam9263ek, at91sam9rlek. This is my
first patch sent to U-Boot and I used that code as reference.

The board that i have (SAM9-L9260 from Olimex ) is close to
AT91SAM9260EK from ATMEL.

How do you think i can do this the right way?

Thanks, good catch. I will fix this and submit a new patch.
