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