If I understand correctly then you want to copy the content of
/dev/nor0.switch to a variable. I'm afraid there currently is no
way to do this in barebox. What information is inside this nor
partition? It seems like you want to implement some kind of redundant
boot and want to decide which rootfs you want to boot. Am I right?
