U-Boot tries to relocate itself as high in RAM as possible so that the
lower area is available to e.g. the Linux kernel it will chainload.

Therefore, the usual process is that U-Boot first reserves whatever
amount of memory it needs at end of RAM, then relocates itself just
below that.

Relocation will always happen, and there is no provision for avoiding
it.
