+ * 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).
