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 | |
e1599e83 | 210 | * a multiple of 4 bytes - except for the last file). |
5b1d7137 WD |
211 | * |
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) | |
27b207fd | 219 | * as command interpreter (=> Shell Scripts). |
