  18. * Memory layout for where various images get loaded by boot scripts:

  20. * scriptaddr can be pretty much anywhere that doesn't conflict with something
  21. * else. Put it above BOOTMAPSZ to eliminate conflicts.

  26. * kernel_addr_r must be within the first 128M of RAM in order for the
  27. * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
  28. * decompress itself to 0x8000 after the start of RAM, kernel_addr_r
  29. * should not overlap that area, or the kernel will have to copy itself
  30. * somewhere else before decompression. Similarly, the address of any other
  31. * data passed to the kernel shouldn't overlap the start of RAM. Pushing
  32. * this up to 16M allows for a sizable kernel to be decompressed below the
  33. * compressed load address.
  34. *
  35. * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
  36. * the compressed kernel to be up to 16M too.
  37. *
  38. * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
  39. * for the FDT/DTB to be up to 1M, which is hopefully plenty.
