44  * scriptaddr can be pretty much anywhere that doesn't conflict with something

49  *
50  * kernel_addr_r must be within the first 128M of RAM in order for the
51  *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
52  *   decompress itself to 0x8000 after the start of RAM, kernel_addr_r
53  *   should not overlap that area, or the kernel will have to copy itself
54  *   somewhere else before decompression. Similarly, the address of any other
55  *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
56  *   this up to 16M allows for a sizable kernel to be decompressed below the
57  *   compressed load address.
58  *
59  * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
60  *   the compressed kernel to be up to 16M too.
61  *
62  * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
63  *   for the FDT/DTB to be up to 1M, which is hopefully plenty.
