47  *
48  * kernel_addr_r must be within the first 128M of RAM in order for the
49  *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
50  *   decompress itself to 0x8000 after the start of RAM, kernel_addr_r
51  *   should not overlap that area, or the kernel will have to copy itself
52  *   somewhere else before decompression. Similarly, the address of any other
53  *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
54  *   this up to 16M allows for a sizable kernel to be decompressed below the
55  *   compressed load address.
56  *
57  * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
58  *   the compressed kernel to be up to 16M too.
59  *
60  * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
61  *   for the FDT/DTB to be up to 1M, which is hopefully plenty.
