 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).
