It doesn't look like this has the ability to provide an external
extlinux.conf file like is done for other loaders, but should.

This order isn't the best order.  We should look for zImage (stock arm32
image), Image (stock arm64 image), fitImage (preferred container in
U-Boot) then uImage (legacy container in U-Boot).  While I'm sure just
vmlinux can work in some cases, I don't think it's appropriate here.
