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).
