My feedback here is the same feedback I gave the last person that wanted
to update the Pi addresses, and I forget if they came back and did that
(and it's in Peter / Matthias' queue) or not. Disabling device tree
relocation is a bug and must be removed.

After that, given the range of memory sizes available on Pi platforms,
allocating the kernel / initrd / kernel decompression buffer at run
time, ala mach-apple would make life easier in the long run.
