  184. * provided by U-Boot; it is expected that (if they behave
  185. * well) you can continue to work in U-Boot after return from
  186. * the Standalone Program.
  187. * "OS Kernel Images" are usually images of some Embedded OS which
  188. * will take over control completely. Usually these programs
  189. * will install their own set of exception handlers, device
  190. * drivers, set up the MMU, etc. - this means, that you cannot
  191. * expect to re-enter U-Boot except by resetting the CPU.
  192. * "RAMDisk Images" are more or less just data blocks, and their
  193. * parameters (address, size) are passed to an OS kernel that is
  194. * being started.
  195. * "Multi-File Images" contain several images, typically an OS
  196. * (Linux) kernel image and one or more data images like
  197. * RAMDisks. This construct is useful for instance when you want
  198. * to boot over the network using BOOTP etc., where the boot
  199. * server provides just a single image file, but you want to get
  200. * for instance an OS kernel and a RAMDisk image.
  201. *
  202. * "Multi-File Images" start with a list of image sizes, each
  203. * image size (in bytes) specified by an "uint32_t" in network
  204. * byte order. This list is terminated by an "(uint32_t)0".
  205. * Immediately after the terminating 0 follow the images, one by
  206. * one, all aligned on "uint32_t" boundaries (size rounded up to
  207. * a multiple of 4 bytes - except for the last file).
  208. *
  209. * "Firmware Images" are binary images containing firmware (like
  210. * U-Boot or FPGA images) which usually will be programmed to
  211. * flash memory.
  212. *
  213. * "Script files" are command sequences that will be executed by
  214. * U-Boot's command interpreter; this feature is especially
  215. * useful when you configure U-Boot to use a real shell (hush)
  216. * as command interpreter (=> Shell Scripts).
  217. *
  218. * The following are exposed to uImage header.
  219. * New IDs *MUST* be appended at the end of the list and *NEVER*
