* - 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.
