Hello Derald,

This would actually make the functionality "not happening" if the 
configuration is done badly, but the Kconfig will still be activated, 
which will contradict it's behavior: enable something, but not working, 
because inside the Makefile, there is a hack to stop it in some cases...
So I would prefer if you can make SPL_GENERATE_ATMEL_PMECC_HEADER depend 
in Kconfig directly to CONFIG_NAND_BOOT.
Does that fit your thoughts as well?

Thanks,
Eugen
