   * using bootm_size. All of the following must be within this range.
   * We have the default load at 32MB into DDR (for the kernel), FDT at
   * 64MB and the ramdisk 512KB above that (allowing for hopefully never
   * seen large trees). This allows a reasonable split between ramdisk
   * and kernel size, where the ram disk can be a bit larger.
