I fail to see why this is something to pursue. Since the distro knows
the boot path, why should u-boot be polling all possible options?

Seems like a logical thing to me, as long as the scripts itself
does not have to bother about board details, but is handed
those info.

It is not an OS issue.

Yes, and the order is wrong in my mind. If anything, it should fallback
to extlinux, but at least use a general boot.scr first. (or
/boot/u-boot.conf
or whatever)
