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