You are wrong. relocation is not useless, even in your case. there
are quite a number of configuration options that will put stuff above
the U-Boot image, directly at the end of RAM (things like protected
RAM, shared frame buffer, shared log buffer, etc.). In these cases,
the relocation address may even be dynamic (i. e. depending on
settings of environment variables, and thus unknown at compile time).

Don't.

The Empire didn't encourage its subjects to go far away, in case they
saw things that might disturb them. For the same reason it had built
a wall around the entire country, patrolled by the Heavenly Guard
whose main function was to tread heavily on the fingers of any inha-
bitants who felt they might like to step outside for five minutes for
a breath of fresh air. - Terry Pratchett, _Mort_
