209 * Image Types

211 * "Standalone Programs" are directly runnable in the environment
212 * provided by U-Boot; it is expected that (if they behave
213 * well) you can continue to work in U-Boot after return from
214 * the Standalone Program.
215 * "OS Kernel Images" are usually images of some Embedded OS which
216 * will take over control completely. Usually these programs
217 * will install their own set of exception handlers, device
218 * drivers, set up the MMU, etc. - this means, that you cannot
219 * expect to re-enter U-Boot except by resetting the CPU.
220 * "RAMDisk Images" are more or less just data blocks, and their
221 * parameters (address, size) are passed to an OS kernel that is
222 * being started.
223 * "Multi-File Images" contain several images, typically an OS
224 * (Linux) kernel image and one or more data images like
225 * RAMDisks. This construct is useful for instance when you want
226 * to boot over the network using BOOTP etc., where the boot
227 * server provides just a single image file, but you want to get
228 * for instance an OS kernel and a RAMDisk image.
229 *
230 * "Multi-File Images" start with a list of image sizes, each
231 * image size (in bytes) specified by an "uint32_t" in network
232 * byte order. This list is terminated by an "(uint32_t)0".
233 * Immediately after the terminating 0 follow the images, one by
234 * one, all aligned on "uint32_t" boundaries (size rounded up to
235 * a multiple of 4 bytes - except for the last file).
236 *
237 * "Firmware Images" are binary images containing firmware (like
238 * U-Boot or FPGA images) which usually will be programmed to
239 * flash memory.
240 *
241 * "Script files" are command sequences that will be executed by
242 * U-Boot's command interpreter; this feature is especially
243 * useful when you configure U-Boot to use a real shell (hush)
244 * as command interpreter (=> Shell Scripts).
245 *
246 * The following are exposed to uImage header.
247 * Do not change values for backward compatibility.
