209  * Image Types
210  *
211  * "Standalone Programs" are directly runnable in the environment
212  *	provided by U-Boot; it is expected that (if they behave
213  *	well) you can continue to work in U-Boot after return from
214  *	the Standalone Program.
215  * "OS Kernel Images" are usually images of some Embedded OS which
216  *	will take over control completely. Usually these programs
217  *	will install their own set of exception handlers, device
218  *	drivers, set up the MMU, etc. - this means, that you cannot
219  *	expect to re-enter U-Boot except by resetting the CPU.
220  * "RAMDisk Images" are more or less just data blocks, and their
221  *	parameters (address, size) are passed to an OS kernel that is
222  *	being started.
223  * "Multi-File Images" contain several images, typically an OS
224  *	(Linux) kernel image and one or more data images like
225  *	RAMDisks. This construct is useful for instance when you want
226  *	to boot over the network using BOOTP etc., where the boot
227  *	server provides just a single image file, but you want to get
228  *	for instance an OS kernel and a RAMDisk image.
229  *
230  *	"Multi-File Images" start with a list of image sizes, each
231  *	image size (in bytes) specified by an "uint32_t" in network
232  *	byte order. This list is terminated by an "(uint32_t)0".
233  *	Immediately after the terminating 0 follow the images, one by
234  *	one, all aligned on "uint32_t" boundaries (size rounded up to
235  *	a multiple of 4 bytes - except for the last file).
236  *
237  * "Firmware Images" are binary images containing firmware (like
238  *	U-Boot or FPGA images) which usually will be programmed to
239  *	flash memory.
240  *
241  * "Script files" are command sequences that will be executed by
242  *	U-Boot's command interpreter; this feature is especially
243  *	useful when you configure U-Boot to use a real shell (hush)
244  *	as command interpreter (=> Shell Scripts).
245  *
246  * The following are exposed to uImage header.
247  * Do not change values for backward compatibility.
