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