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