/*
 * 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).
