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