184 * Image Types
185 *
186 * "Standalone Programs" are directly runnable in the environment
187 * provided by U-Boot; it is expected that (if they behave
188 * well) you can continue to work in U-Boot after return from
189 * the Standalone Program.
190 * "OS Kernel Images" are usually images of some Embedded OS which
191 * will take over control completely. Usually these programs
192 * will install their own set of exception handlers, device
193 * drivers, set up the MMU, etc. - this means, that you cannot
194 * expect to re-enter U-Boot except by resetting the CPU.
195 * "RAMDisk Images" are more or less just data blocks, and their
196 * parameters (address, size) are passed to an OS kernel that is
197 * being started.
198 * "Multi-File Images" contain several images, typically an OS
199 * (Linux) kernel image and one or more data images like
200 * RAMDisks. This construct is useful for instance when you want
201 * to boot over the network using BOOTP etc., where the boot
202 * server provides just a single image file, but you want to get
203 * for instance an OS kernel and a RAMDisk image.
204 *
205 * "Multi-File Images" start with a list of image sizes, each
206 * image size (in bytes) specified by an "uint32_t" in network
207 * byte order. This list is terminated by an "(uint32_t)0".
208 * Immediately after the terminating 0 follow the images, one by
209 * one, all aligned on "uint32_t" boundaries (size rounded up to
wdenke1599e82004-10-10 23:27:33 +0000210 * a multiple of 4 bytes - except for the last file).
wdenk5b1d7132002-11-03 00:07:02 +0000211 *
212 * "Firmware Images" are binary images containing firmware (like
213 * U-Boot or FPGA images) which usually will be programmed to
214 * flash memory.
215 *
216 * "Script files" are command sequences that will be executed by
217 * U-Boot's command interpreter; this feature is especially
218 * useful when you configure U-Boot to use a real shell (hush)
wdenk27b207f2003-07-24 23:38:38 +0000219 * as command interpreter (=> Shell Scripts).
