  25 * Memory layout for where various images get loaded by boot scripts:
  26 *
  27 * scriptaddr can be pretty much anywhere that doesn't conflict with something
  28 *   else. Put it above BOOTMAPSZ to eliminate conflicts.
  29 *
  30 * pxefile_addr_r can be pretty much anywhere that doesn't conflict with
  31 *   something else. Put it above BOOTMAPSZ to eliminate conflicts.
  32 *
  33 * kernel_addr_r must be within the first 128M of RAM in order for the
  34 *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
  35 *   decompress itself to 0x8000 after the start of RAM, kernel_addr_r
  36 *   should not overlap that area, or the kernel will have to copy itself
  37 *   somewhere else before decompression. Similarly, the address of any other
  38 *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
  39 *   this up to 32M allows for a sizable kernel to be decompressed below the
  40 *   compressed load address.
  41 *
  42 * fdt_addr_r simply shouldn't overlap anything else. Choosing 48M allows for
  43 *   the compressed kernel to be up to 32M too.
  44 *
  45 * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 49M allows
  46 *   for the FDT/DTB to be up to 1M, which is hopefully plenty.
