	19	* Continue booting an OS image; caller already has:
	20	* - copied image header to global variable `header'
	21	* - checked header magic number, checksums (both header & image),
	22	* - verified image architecture (PPC) and type (KERNEL or MULTI),
	23	* - loaded (first part of) image to header load address,
	24	* - disabled interrupts.
	25	*
	26	* @flag: Flags indicating what to do (BOOTM_STATE_...)
	27	* @argc: Number of arguments. Note that the arguments are shifted down
	28	* so that 0 is the first argument not processed by U-Boot, and
	29	* argc is adjusted accordingly. This avoids confusion as to how
	30	* many arguments are available for the OS.
	31	* @images: Pointers to os/initrd/fdt
	32	* @return 1 on error. On success the OS boots so this function does
	33	* not return.
