- Nand flash.
- - Nor falsh (not populate by default)

You can choose your storage location at config step (here for at91sam9260ek) :
make at91sam9263ek_config - use data flash (spi cs0) (default)
make at91sam9263ek_nandflash_config - use nand flash

- make at91sam9263ek_norflash_config - use nor falsh

You can choose to boot directly from U-Boot at config step
- make at91sam9263ek_norflash_boot_config - boot from nor falsh
