 *  - copied image header to global variable `header'
 *  - checked header magic number, checksums (both header & image),
 *  - verified image architecture (PPC) and type (KERNEL or MULTI),
 *  - loaded (first part of) image to header load address,
 *  - disabled interrupts.
 *
 * @flag: Flags indicating what to do (BOOTM_STATE_...)
 * @argc: Number of arguments. Note that the arguments are shifted down
 *	 so that 0 is the first argument not processed by U-Boot, and
 *	 argc is adjusted accordingly. This avoids confusion as to how
 *	 many arguments are available for the OS.
 * @images: Pointers to os/initrd/fdt
 * @return 1 on error. On success the OS boots so this function does
 * not return.
