On the at91sam9260ep development board there is an EEPROM connected to the TWI interface (PA23, PA24 Peripheral A multiplexing), so we cannot use these pins as ETX2, ETX3. This patch configures PA10, PA11 pins for ETX2, ETX3 instead of PA23, PA24 pins.

Hi Manuel,
Wolfgang Denk asked you in another email for a proper patch to fix this issue so that this could be reviewed on the list and applied by AT91 custodian. Now I created this patch and a patch description, but I'm not familiar with at91sam9260 and also do not have an at91sam9260ep board and cannot test it.
Could you please test this patch and probably fix the patch description. I composed this description from info in your mails, but I'm not sure if it is really correct. Also add your "Signed-off-by" line.
