What do you mean with 'simple' FIT image? What does it contain?

What do you mean with 'installed to /boot'? Buildroot does not install
anything to /boot, and if you were talking about the target itself,
many targets do not work with such a /boot partition/directory.

If the user is to supply an .its file himself (which I found most
logical so that he/she has most flexibility) then we don't have to
treat any of these cases directly right?

The user specifies in an its file which components it contains, and
whether the vmlinux image contains initramfs or not is not relevant
for us, we just call 'mkimage' on it.

I may be missing something, so please clarify.
