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

  29. * kernel_addr_r must be within the first 128M of RAM in order for the
  30. * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
  31. * decompress itself to 0x8000 after the start of RAM, kernel_addr_r
  32. * should not overlap that area, or the kernel will have to copy itself
  33. * somewhere else before decompression. Similarly, the address of any other
  34. * data passed to the kernel shouldn't overlap the start of RAM. Pushing
  35. * this up to 32M allows for a sizable kernel to be decompressed below the
  36. * compressed load address.
  37. *
  38. * fdt_addr_r simply shouldn't overlap anything else. Choosing 48M allows for
  39. * the compressed kernel to be up to 32M too.
  40. *
  41. * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 49M allows
  42. * for the FDT/DTB to be up to 1M, which is hopefully plenty.
