 208  * Image Types
 209  *
 210  * "Standalone Programs" are directly runnable in the environment
 211  *      provided by U-Boot; it is expected that (if they behave
 212  *      well) you can continue to work in U-Boot after return from
 213  *      the Standalone Program.
 214  * "OS Kernel Images" are usually images of some Embedded OS which
 215  *      will take over control completely. Usually these programs
 216  *      will install their own set of exception handlers, device
 217  *      drivers, set up the MMU, etc. - this means, that you cannot
 218  *      expect to re-enter U-Boot except by resetting the CPU.
 219  * "RAMDisk Images" are more or less just data blocks, and their
 220  *      parameters (address, size) are passed to an OS kernel that is
 221  *      being started.
 222  * "Multi-File Images" contain several images, typically an OS
 223  *      (Linux) kernel image and one or more data images like
 224  *      RAMDisks. This construct is useful for instance when you want
 225  *      to boot over the network using BOOTP etc., where the boot
 226  *      server provides just a single image file, but you want to get
 227  *      for instance an OS kernel and a RAMDisk image.
 228  *
 229  *      "Multi-File Images" start with a list of image sizes, each
 230  *      image size (in bytes) specified by an "uint32_t" in network
 231  *      byte order. This list is terminated by an "(uint32_t)0".
 232  *      Immediately after the terminating 0 follow the images, one by
 233  *      one, all aligned on "uint32_t" boundaries (size rounded up to
 234  *      a multiple of 4 bytes - except for the last file).
 235  *
 236  * "Firmware Images" are binary images containing firmware (like
 237  *      U-Boot or FPGA images) which usually will be programmed to
 238  *      flash memory.
 239  *
 240  * "Script files" are command sequences that will be executed by
 241  *      U-Boot's command interpreter; this feature is especially
 242  *      useful when you configure U-Boot to use a real shell (hush)
 243  *      as command interpreter (=> Shell Scripts).
 244  *
 245  * The following are exposed to uImage header.
 246  * Do not change values for backward compatibility.
