/*

 * 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).
