u-boot-spl.bin is just the SPL. u-boot-with-spl.bin is SPL plus u-boot.

Or maybe the former could just become spl.bin, and then u-boot-spl.bin
could mean the latter? There's really no reason to put "u-boot" in the
name of every intermediate file that represents something more specific.

It's useful to leave intermediate files around for debugging.

If the only thing Tegra-specific about the output format is that it has
a dtb bundled, I think it should have a more generic name, as other
targets could end up using a dtb as well.
