* scriptaddr can be pretty much anywhere that doesn't conflict with something

*
* 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.
*
* fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
* the compressed kernel to be up to 16M too.
*
* ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
* for the FDT/DTB to be up to 1M, which is hopefully plenty.
