  31  * DDR3. Hence, limit the memory range for image processing to 112MB
  32  * using bootm_size. All of the following must be within this range.
  33  * We have the default load at 32MB into DDR (for the kernel), FDT at

  35  * seen large trees). This allows a reasonable split between ramdisk
  36  * and kernel size, where the ram disk can be a bit larger.
