 113  * Image Types
 114  *
 115  * "Standalone Programs" are directly runnable in the environment
 116  *      provided by U-Boot; it is expected that (if they behave
 117  *      well) you can continue to work in U-Boot after return from
 118  *      the Standalone Program.
 119  * "OS Kernel Images" are usually images of some Embedded OS which
 120  *      will take over control completely. Usually these programs
 121  *      will install their own set of exception handlers, device
 122  *      drivers, set up the MMU, etc. - this means, that you cannot
 123  *      expect to re-enter U-Boot except by resetting the CPU.
 124  * "RAMDisk Images" are more or less just data blocks, and their
 125  *      parameters (address, size) are passed to an OS kernel that is
 126  *      being started.
 127  * "Multi-File Images" contain several images, typically an OS
 128  *      (Linux) kernel image and one or more data images like
 129  *      RAMDisks. This construct is useful for instance when you want
 130  *      to boot over the network using BOOTP etc., where the boot
 131  *      server provides just a single image file, but you want to get
 132  *      for instance an OS kernel and a RAMDisk image.
 133  *
 134  *      "Multi-File Images" start with a list of image sizes, each
 135  *      image size (in bytes) specified by an "uint32_t" in network
 136  *      byte order. This list is terminated by an "(uint32_t)0".
 137  *      Immediately after the terminating 0 follow the images, one by
 138  *      one, all aligned on "uint32_t" boundaries (size rounded up to
 139  *      a multiple of 4 bytes - except for the last file).
 140  *
 141  * "Firmware Images" are binary images containing firmware (like
 142  *      U-Boot or FPGA images) which usually will be programmed to
 143  *      flash memory.
 144  *
 145  * "Script files" are command sequences that will be executed by
 146  *      U-Boot's command interpreter; this feature is especially
 147  *      useful when you configure U-Boot to use a real shell (hush)
 148  *      as command interpreter (=> Shell Scripts).
