114 * Image Types
115 *
116 * "Standalone Programs" are directly runnable in the environment
117 * provided by U-Boot; it is expected that (if they behave
118 * well) you can continue to work in U-Boot after return from
119 * the Standalone Program.
120 * "OS Kernel Images" are usually images of some Embedded OS which
121 * will take over control completely. Usually these programs
122 * will install their own set of exception handlers, device
123 * drivers, set up the MMU, etc. - this means, that you cannot
124 * expect to re-enter U-Boot except by resetting the CPU.
125 * "RAMDisk Images" are more or less just data blocks, and their
126 * parameters (address, size) are passed to an OS kernel that is
127 * being started.
128 * "Multi-File Images" contain several images, typically an OS
129 * (Linux) kernel image and one or more data images like
130 * RAMDisks. This construct is useful for instance when you want
131 * to boot over the network using BOOTP etc., where the boot
132 * server provides just a single image file, but you want to get
133 * for instance an OS kernel and a RAMDisk image.
134 *
135 * "Multi-File Images" start with a list of image sizes, each
136 * image size (in bytes) specified by an "uint32_t" in network
137 * byte order. This list is terminated by an "(uint32_t)0".
138 * Immediately after the terminating 0 follow the images, one by
139 * one, all aligned on "uint32_t" boundaries (size rounded up to
wdenke1599e82004-10-10 23:27:33 +0000140 * a multiple of 4 bytes - except for the last file).
wdenk5b1d7132002-11-03 00:07:02 +0000141 *
142 * "Firmware Images" are binary images containing firmware (like
143 * U-Boot or FPGA images) which usually will be programmed to
144 * flash memory.
145 *
146 * "Script files" are command sequences that will be executed by
147 * U-Boot's command interpreter; this feature is especially
148 * useful when you configure U-Boot to use a real shell (hush)
wdenk27b207f2003-07-24 23:38:38 +0000149 * as command interpreter (=> Shell Scripts).
