 111 * Image Types
 112 *
 113 * "Standalone Programs" are directly runnable in the environment
 114 *      provided by U-Boot; it is expected that (if they behave
 115 *      well) you can continue to work in U-Boot after return from
 116 *      the Standalone Program.
 117 * "OS Kernel Images" are usually images of some Embedded OS which
 118 *      will take over control completely. Usually these programs
 119 *      will install their own set of exception handlers, device
 120 *      drivers, set up the MMU, etc. - this means, that you cannot
 121 *      expect to re-enter U-Boot except by resetting the CPU.
 122 * "RAMDisk Images" are more or less just data blocks, and their
 123 *      parameters (address, size) are passed to an OS kernel that is
 124 *      being started.
 125 * "Multi-File Images" contain several images, typically an OS
 126 *      (Linux) kernel image and one or more data images like
 127 *      RAMDisks. This construct is useful for instance when you want
 128 *      to boot over the network using BOOTP etc., where the boot
 129 *      server provides just a single image file, but you want to get
 130 *      for instance an OS kernel and a RAMDisk image.
 131 *
 132 *      "Multi-File Images" start with a list of image sizes, each
 133 *      image size (in bytes) specified by an "uint32_t" in network
 134 *      byte order. This list is terminated by an "(uint32_t)0".
 135 *      Immediately after the terminating 0 follow the images, one by
 136 *      one, all aligned on "uint32_t" boundaries (size rounded up to
 137 *      a multiple of 4 bytes - except for the last file).
 138 *
 139 * "Firmware Images" are binary images containing firmware (like
 140 *      U-Boot or FPGA images) which usually will be programmed to
 141 *      flash memory.
 142 *
 143 * "Script files" are command sequences that will be executed by
 144 *      U-Boot's command interpreter; this feature is especially
 145 *      useful when you configure U-Boot to use a real shell (hush)
 146 *      as command interpreter (=> Shell Scripts).
