27  * Memory layout for where various images get loaded by boot scripts:
28  *
29  * scriptaddr can be pretty much anywhere that doesn't conflict with something
30  *   else. Put it above BOOTMAPSZ to eliminate conflicts.
31  *
32  * pxefile_addr_r can be pretty much anywhere that doesn't conflict with
33  *   something else. Put it above BOOTMAPSZ to eliminate conflicts.
34  *
35  * kernel_addr_r must be within the first 128M of RAM in order for the
36  *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
37  *   decompress itself to 0x8000 after the start of RAM, kernel_addr_r
38  *   should not overlap that area, or the kernel will have to copy itself
39  *   somewhere else before decompression. Similarly, the address of any other
40  *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
41  *   this up to 16M allows for a sizable kernel to be decompressed below the
42  *   compressed load address.
43  *
44  * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
45  *   the compressed kernel to be up to 16M too.
46  *
47  * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
48  *   for the FDT/DTB to be up to 1M, which is hopefully plenty.
