  197. * Image Types
  198. *
  199. * "Standalone Programs" are directly runnable in the environment
  200. * provided by U-Boot; it is expected that (if they behave
  201. * well) you can continue to work in U-Boot after return from
  202. * the Standalone Program.
  203. * "OS Kernel Images" are usually images of some Embedded OS which
  204. * will take over control completely. Usually these programs
  205. * will install their own set of exception handlers, device
  206. * drivers, set up the MMU, etc. - this means, that you cannot
  207. * expect to re-enter U-Boot except by resetting the CPU.
  208. * "RAMDisk Images" are more or less just data blocks, and their
  209. * parameters (address, size) are passed to an OS kernel that is
  210. * being started.
  211. * "Multi-File Images" contain several images, typically an OS
  212. * (Linux) kernel image and one or more data images like
  213. * RAMDisks. This construct is useful for instance when you want
  214. * to boot over the network using BOOTP etc., where the boot
  215. * server provides just a single image file, but you want to get
  216. * for instance an OS kernel and a RAMDisk image.
  217. *
  218. * "Multi-File Images" start with a list of image sizes, each
  219. * image size (in bytes) specified by an "uint32_t" in network
  220. * byte order. This list is terminated by an "(uint32_t)0".
  221. * Immediately after the terminating 0 follow the images, one by
  222. * one, all aligned on "uint32_t" boundaries (size rounded up to
  223. * a multiple of 4 bytes - except for the last file).
  224. *
  225. * "Firmware Images" are binary images containing firmware (like
  226. * U-Boot or FPGA images) which usually will be programmed to
  227. * flash memory.
  228. *
  229. * "Script files" are command sequences that will be executed by
  230. * U-Boot's command interpreter; this feature is especially
  231. * useful when you configure U-Boot to use a real shell (hush)
  232. * as command interpreter (=> Shell Scripts).
  233. *
  234. * The following are exposed to uImage header.
  235. * New IDs *MUST* be appended at the end of the list and *NEVER*
  236. * inserted for backward compatibility.
