This is a global file, so maybe we could use a less specific #define
than CONFIG_NAND_SPL for this? Eventually we need this later to boot
from device FOO, and I don't want to see this grow into

if !defined(CONFIG_NAND_SPL) && !defined(CONFIG_FOO) && !defined(CONFIG_BAR) && ...

Thanks.

Best regards,
