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

34  * scriptaddr can be pretty much anywhere that doesn't conflict with something
35  *   else. Put it above BOOTMAPSZ to eliminate conflicts.
36  *
37  * pxefile_addr_r can be pretty much anywhere that doesn't conflict with

39  *
40  * kernel_addr_r must be within the first 128M of RAM in order for the
41  *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
42  *   decompress itself to 0x8000 after the start of RAM, kernel_addr_r
43  *   should not overlap that area, or the kernel will have to copy itself
44  *   somewhere else before decompression. Similarly, the address of any other
45  *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
46  *   this up to 16M allows for a sizable kernel to be decompressed below the
47  *   compressed load address.
48  *
49  * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
50  *   the compressed kernel to be up to 16M too.
51  *
52  * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
53  *   for the FDT/DTB to be up to 1M, which is hopefully plenty.
