If you're using -kernel you don't need to provide a u-boot
because qemu is being the bootloader. If you're making
qemu execute a bootloader than you should just put the
kernel where u-boot would load it normally.

We really can't add random options to qemu to support
loading every single thing you might possibly want to load,
which is why I'm drawing a line in the sand here.
