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. -- 2.39.5
