63  *
64  * kernel_addr_r must be within the first 128M of RAM in order for the
65  *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
66  *   decompress itself to 0x8000 after the start of RAM, kernel_addr_r
67  *   should not overlap that area, or the kernel will have to copy itself
68  *   somewhere else before decompression. Similarly, the address of any other
69  *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
70  *   this up to 16M allows for a sizable kernel to be decompressed below the
71  *   compressed load address.
72  *
73  * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
74  *   the compressed kernel to be up to 16M too.
75  *
76  * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
77  *   for the FDT/DTB to be up to 1M, which is hopefully plenty.
