Subject: nand flash: fix timings for at91sam9x evaluation kits
From: Patrice Vilchez <patrice.vilchez@xxxxxxxxx>
Fix NAND FLASH timings for at91sam9x evaluation kits.
New timings are based on application note
"NAND Flash Support on AT91SAM9 Microcontrollers" available at
http://atmel.com/dyn/resources/prod_documents/doc6255.pdf).
