- Nand flash.
You can choose your storage location at config step (here for at91sam9260ek) :
- make at91sam9260ek_config - use data flash (spi cs1) (default)
make at91sam9260ek_nandflash_config - use nand flash
make at91sam9260ek_dataflash_cs0_config - use data flash (spi cs0)
make at91sam9260ek_dataflash_cs1_config - use data flash (spi cs1)

U-Boot environment variables can be stored at different places:
- Dataflash on SPI chip select 0 (dataflash card)
- Nand flash.
- - Nor falsh (not populate by default)
+ - Nor flash (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)
