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.
