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