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