u-boot.bin is a raw binary which does not contain any sort of "files".
You cannot extract what's not there in the first place.  And you
cannot find tools to perform tasks that are impossible.

Well, that's a prtty strong statement given that 1) you ignore the
netiquette (you top-post / full-quote) and dropped the ML from Cc:,
and 2) you appear to have only very limited understanding of what
u-boot.bin actually is.

There is sufficient tools for all kinds of file manipulation
available, but only for possible manipulations.  It's like mixing
chemicals - for example, once you mixed UDMH and nitrogen tetroxide,
it will be very difficult to find tools to separate (i. e.
"decompile") these again (for several reasons :-)

Some operations are simply irreversible.

Best regards,

Wolfgang Denk
