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.
