  29  * Memory layout for where various images get loaded by boot scripts:
  30  *
  31  * scriptaddr can be pretty much anywhere that doesn't conflict with something
  32  *   else. Put it above BOOTMAPSZ to eliminate conflicts.
  33  *
  34  * pxefile_addr_r can be pretty much anywhere that doesn't conflict with
  35  *   something else. Put it above BOOTMAPSZ to eliminate conflicts.
  36  *
  37  * kernel_addr_r must be within the first 128M of RAM in order for the
  38  *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
  39  *   decompress itself to 0x8000 after the start of RAM, kernel_addr_r
  40  *   should not overlap that area, or the kernel will have to copy itself
  41  *   somewhere else before decompression. Similarly, the address of any other
  42  *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
  43  *   this up to 16M allows for a sizable kernel to be decompressed below the
  44  *   compressed load address.
  45  *
  46  * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
  47  *   the compressed kernel to be up to 16M too.
  48  *
  49  * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
  50  *   for the FDT/DTB to be up to 1M, which is hopefully plenty.
