+ * 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).
