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
140  * a multiple of 4 bytes - except for the last file).
141  *
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)
149  * as command interpreter (=> Shell Scripts).
