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