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)
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_dataflash_cs0_config - use data flash (spi cs0)
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

implemented in the X-Loader, so U-Boot is already running in SDRAM

The Makefile offers two different configurations to be used if you
boot from Nand or OneNand.
make nhk8815_config
make nhk8815_onenand_config
Both support OneNand and Nand. Since U-Boot, running in RAM, can't know
where it was loaded from, the configurations differ in where the filesystem
