How do you do that? The same way you format a USB stick when you insert it. If you have built-in versus removable, then we should expose that information to userspace rather than some arbitrary encoding in DT that 0 means built-in and 1 means removable. Or if you have multiple slots, then use "label" to provide meaningful slot names.
