  61  * scriptaddr can be pretty much anywhere that doesn't conflict with something
  62  *   else. Put it above BOOTMAPSZ to eliminate conflicts.
  63  *
  64  * kernel_addr_r must be within the first 128M of RAM in order for the
  65  *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
  66  *   decompress itself to 0x8000 after the start of RAM, kernel_addr_r
  67  *   should not overlap that area, or the kernel will have to copy itself
  68  *   somewhere else before decompression. Similarly, the address of any other
  69  *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
  70  *   this up to 16M allows for a sizable kernel to be decompressed below the
  71  *   compressed load address.
  72  *
  73  * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
  74  *   the compressed kernel to be up to 16M too.
  75  *
  76  * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
  77  *   for the FDT/DTB to be up to 1M, which is hopefully plenty.
