94 * "Standalone Programs" are directly runnable in the environment
95 * provided by U-Boot; it is expected that (if they behave
96 * well) you can continue to work in U-Boot after return from
97 * the Standalone Program.
98 * "OS Kernel Images" are usually images of some Embedded OS which
99 * will take over control completely. Usually these programs
100 * will install their own set of exception handlers, device
101 * drivers, set up the MMU, etc. - this means, that you cannot
102 * expect to re-enter U-Boot except by resetting the CPU.
103 * "RAMDisk Images" are more or less just data blocks, and their
104 * parameters (address, size) are passed to an OS kernel that is
106 * "Multi-File Images" contain several images, typically an OS
107 * (Linux) kernel image and one or more data images like
108 * RAMDisks. This construct is useful for instance when you want
109 * to boot over the network using BOOTP etc., where the boot
110 * server provides just a single image file, but you want to get
111 * for instance an OS kernel and a RAMDisk image.
113 * "Multi-File Images" start with a list of image sizes, each
114 * image size (in bytes) specified by an "uint32_t" in network
115 * byte order. This list is terminated by an "(uint32_t)0".
116 * Immediately after the terminating 0 follow the images, one by
117 * one, all aligned on "uint32_t" boundaries (size rounded up to
118 * a multiple of 4 bytes - except for the last file).
120 * "Firmware Images" are binary images containing firmware (like
121 * U-Boot or FPGA images) which usually will be programmed to
124 * "Script files" are command sequences that will be executed by
125 * U-Boot's command interpreter; this feature is especially
126 * useful when you configure U-Boot to use a real shell (hush)
127 * as command interpreter (=> Shell Scripts).
