     27  * scriptaddr can be pretty much anywhere that doesn't conflict with something
     28  *   else. Put it above BOOTMAPSZ to eliminate conflicts.

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

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