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