110  * Image Types
111  *
112  * "Standalone Programs" are directly runnable in the environment
113  *	provided by U-Boot; it is expected that (if they behave
114  *	well) you can continue to work in U-Boot after return from
115  *	the Standalone Program.
116  * "OS Kernel Images" are usually images of some Embedded OS which
117  *	will take over control completely. Usually these programs
118  *	will install their own set of exception handlers, device
119  *	drivers, set up the MMU, etc. - this means, that you cannot
120  *	expect to re-enter U-Boot except by resetting the CPU.
121  * "RAMDisk Images" are more or less just data blocks, and their
122  *	parameters (address, size) are passed to an OS kernel that is
123  *	being started.
124  * "Multi-File Images" contain several images, typically an OS
125  *	(Linux) kernel image and one or more data images like
126  *	RAMDisks. This construct is useful for instance when you want
127  *	to boot over the network using BOOTP etc., where the boot
128  *	server provides just a single image file, but you want to get
129  *	for instance an OS kernel and a RAMDisk image.
130  *
131  *	"Multi-File Images" start with a list of image sizes, each
132  *	image size (in bytes) specified by an "uint32_t" in network
133  *	byte order. This list is terminated by an "(uint32_t)0".
134  *	Immediately after the terminating 0 follow the images, one by
135  *	one, all aligned on "uint32_t" boundaries (size rounded up to
136  *	a multiple of 4 bytes - except for the last file).
137  *
138  * "Firmware Images" are binary images containing firmware (like
139  *	U-Boot or FPGA images) which usually will be programmed to
140  *	flash memory.
141  *
142  * "Script files" are command sequences that will be executed by
143  *	U-Boot's command interpreter; this feature is especially
144  *	useful when you configure U-Boot to use a real shell (hush)
145  *	as command interpreter (=> Shell Scripts).
