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