# During boot, when uboot try to load above "uImage", it will know to load it (without image head added by mkimage tool) into 0x90008000 or 0x70008000 (specified by "-a"), and then jump to 0x90008000 or 0x70008000 (specified by "-e") to execute it. "-C none" means no compression when generating "uImage". This is because the original zImage is already a compressed one.
