I've pushed 3 patches on a branch[1]. It is mostly untested, but it
should allow the above RPi3 disaster to cope with kexec.

I threw the kernel on my RPi3+ model but I wasn't able to start the crash
kernel. Unfortunately I don't have a JTAG adapter to check if it hangs for the
same reason.

Have you annotated the RPi3 root irq_chip structure so that the arm64
kexec code knows that this is the root interrupt controller? I've only
done so on the GIC drivers.
