187 * Image Types
188 *
189 * "Standalone Programs" are directly runnable in the environment
190 * provided by U-Boot; it is expected that (if they behave
191 * well) you can continue to work in U-Boot after return from
192 * the Standalone Program.
193 * "OS Kernel Images" are usually images of some Embedded OS which
194 * will take over control completely. Usually these programs
195 * will install their own set of exception handlers, device
196 * drivers, set up the MMU, etc. - this means, that you cannot
197 * expect to re-enter U-Boot except by resetting the CPU.
198 * "RAMDisk Images" are more or less just data blocks, and their
199 * parameters (address, size) are passed to an OS kernel that is
200 * being started.
201 * "Multi-File Images" contain several images, typically an OS
202 * (Linux) kernel image and one or more data images like
203 * RAMDisks. This construct is useful for instance when you want
204 * to boot over the network using BOOTP etc., where the boot
205 * server provides just a single image file, but you want to get
206 * for instance an OS kernel and a RAMDisk image.
207 *
208 * "Multi-File Images" start with a list of image sizes, each
209 * image size (in bytes) specified by an "uint32_t" in network
210 * byte order. This list is terminated by an "(uint32_t)0".
211 * Immediately after the terminating 0 follow the images, one by
212 * one, all aligned on "uint32_t" boundaries (size rounded up to
213 * a multiple of 4 bytes - except for the last file).
214 *
215 * "Firmware Images" are binary images containing firmware (like
216 * U-Boot or FPGA images) which usually will be programmed to
217 * flash memory.
218 *
219 * "Script files" are command sequences that will be executed by
220 * U-Boot's command interpreter; this feature is especially
221 * useful when you configure U-Boot to use a real shell (hush)
222 * as command interpreter (=> Shell Scripts).
