RE: [yocto] Recipes to modify variable UBOOT_CONFIG?

Variables set in one recipe (image) are valid only in that recipe and not others (u-boot).
What you want is to generate two u-boots (put both options to UBOOT_CONFIG in machine) and let the image decide which one to use.
Or make your single u-boot support both boot methods if possible.
