 * Memory layout for where various images get loaded by boot scripts:

 * I suspect address 0 is used as the SMP pen on the RPi2, so avoid this.
 *
 * fdt_addr_r simply shouldn't overlap anything else. However, the RPi's
 *   binary firmware loads a DT to address 0x100, so we choose this address to
 *   match it. This allows custom boot scripts to pass this DT on to Linux
 *   simply by not over-writing the data at this address. When using U-Boot,
 *   U-Boot (and scripts it executes) typicaly ignore the DT loaded by the FW
 *   and loads its own DT from disk (triggered by boot.scr or extlinux.conf).
 *
 * pxefile_addr_r can be pretty much anywhere that doesn't conflict with
 *   something else. Put it low in memory to avoid conflicts.
 *
 * kernel_addr_r must be within the first 128M of RAM in order for the
 *   kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
 *   decompress itself to 0x8000 after the start of RAM, kernel_addr_r
 *   should not overlap that area, or the kernel will have to copy itself
 *   somewhere else before decompression. Similarly, the address of any other
 *   data passed to the kernel shouldn't overlap the start of RAM. Pushing
 *   this up to 16M allows for a sizable kernel to be decompressed below the
 *   compressed load address.
 *
 * scriptaddr can be pretty much anywhere that doesn't conflict with something
 *   else. Choosing 32M allows for the compressed kernel to be up to 16M.
 *
 * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
 *   for any boot script to be up to 1M, which is hopefully plenty.
