U-Boot expects to be linked to a specific hard-coded address, and to
be loaded to and run from that address. This option lifts that
- restriction, thus allowing the code to be loaded to and executed
- from almost any address. This logic relies on the relocation
+ restriction, thus allowing the code to be loaded to and executed from
+ almost any 4K aligned address. This logic relies on the relocation
information that is embedded in the binary to support U-Boot
relocating itself to the top-of-RAM later during execution.
