26  * pxefile_addr_r can be pretty much anywhere that doesn't conflict with

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