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