U-Boot just prepends a 64 byte header (see include/image.h).

So "dd if=uImage of=kernel bs=64 skip=1" will do the job, as will
"tail -c +65 uImage >kernel".

No need for special tools. Just use the  standard  Unix  toolbox  for
file manipulation commands.

They weren't that important. They were merely at the top. The  people
who  really  run organizations are usually found several levels down,
where it's still possible to get things done.
