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