  102. * Image Types
  103. *
  104. * "Standalone Programs" are directly runnable in the environment
  105. * provided by U-Boot; it is expected that (if they behave
  106. * well) you can continue to work in U-Boot after return from
  107. * the Standalone Program.
  108. * "OS Kernel Images" are usually images of some Embedded OS which
  109. * will take over control completely. Usually these programs
  110. * will install their own set of exception handlers, device
  111. * drivers, set up the MMU, etc. - this means, that you cannot
  112. * expect to re-enter U-Boot except by resetting the CPU.
  113. * "RAMDisk Images" are more or less just data blocks, and their
  114. * parameters (address, size) are passed to an OS kernel that is
  115. * being started.
  116. * "Multi-File Images" contain several images, typically an OS
  117. * (Linux) kernel image and one or more data images like
  118. * RAMDisks. This construct is useful for instance when you want
  119. * to boot over the network using BOOTP etc., where the boot
  120. * server provides just a single image file, but you want to get
  121. * for instance an OS kernel and a RAMDisk image.
  122. *
  123. * "Multi-File Images" start with a list of image sizes, each
  124. * image size (in bytes) specified by an "uint32_t" in network
  125. * byte order. This list is terminated by an "(uint32_t)0".
  126. * Immediately after the terminating 0 follow the images, one by
  127. * one, all aligned on "uint32_t" boundaries (size rounded up to
  128. * a multiple of 4 bytes - except for the last file).
  129. *
  130. * "Firmware Images" are binary images containing firmware (like
  131. * U-Boot or FPGA images) which usually will be programmed to
  132. * flash memory.
  133. *
  134. * "Script files" are command sequences that will be executed by
  135. * U-Boot's command interpreter; this feature is especially
  136. * useful when you configure U-Boot to use a real shell (hush)
  137. * as command interpreter (=> Shell Scripts).
