But, since the u-boot-spl.img (including the 64 byte header) is loaded by the SoC as the main image, we need to compensate for the header length to get a correct entry point. Thus, we subtract the header size from the destination address, so that the execution address points at the actual entry point of the image. The current boards ignore both parameters anyway, so this change shouldn't concern them.
