 172  * Image Types
 173  *
 174  * "Standalone Programs" are directly runnable in the environment
 175  *      provided by U-Boot; it is expected that (if they behave
 176  *      well) you can continue to work in U-Boot after return from
 177  *      the Standalone Program.
 178  * "OS Kernel Images" are usually images of some Embedded OS which
 179  *      will take over control completely. Usually these programs
 180  *      will install their own set of exception handlers, device
 181  *      drivers, set up the MMU, etc. - this means, that you cannot
 182  *      expect to re-enter U-Boot except by resetting the CPU.
 183  * "RAMDisk Images" are more or less just data blocks, and their
 184  *      parameters (address, size) are passed to an OS kernel that is
 185  *      being started.
 186  * "Multi-File Images" contain several images, typically an OS
 187  *      (Linux) kernel image and one or more data images like
 188  *      RAMDisks. This construct is useful for instance when you want
 189  *      to boot over the network using BOOTP etc., where the boot
 190  *      server provides just a single image file, but you want to get
 191  *      for instance an OS kernel and a RAMDisk image.
 192  *
 193  *      "Multi-File Images" start with a list of image sizes, each
 194  *      image size (in bytes) specified by an "uint32_t" in network
 195  *      byte order. This list is terminated by an "(uint32_t)0".
 196  *      Immediately after the terminating 0 follow the images, one by
 197  *      one, all aligned on "uint32_t" boundaries (size rounded up to
 198  *      a multiple of 4 bytes - except for the last file).
 199  *
 200  * "Firmware Images" are binary images containing firmware (like
 201  *      U-Boot or FPGA images) which usually will be programmed to
 202  *      flash memory.
 203  *
 204  * "Script files" are command sequences that will be executed by
 205  *      U-Boot's command interpreter; this feature is especially
 206  *      useful when you configure U-Boot to use a real shell (hush)
 207  *      as command interpreter (=> Shell Scripts).
