 142  * Memory layout for where various images get loaded by boot scripts:
 143  *
 144  * scriptaddr can be pretty much anywhere that doesn't conflict with something
 145  *   else. Put it above BOOTMAPSZ to eliminate conflicts.
 146  *
 147  * kernel_addr_r must be within the first 128M of RAM in order for the
 148  *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
 149  *   decompress itself to 0x8000 after the start of RAM, kernel_addr_r
 150  *   should not overlap that area, or the kernel will have to copy itself
 151  *   somewhere else before decompression. Similarly, the address of any other
 152  *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
 153  *   this up to 16M allows for a sizable kernel to be decompressed below the
 154  *   compressed load address.
 155  *
 156  * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
 157  *   the compressed kernel to be up to 16M too.
 158  *
 159  * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
 160  *   for the FDT/DTB to be up to 1M, which is hopefully plenty.
