So, booti is very much for the "Image" format described in the Linux
kernel in Documentation/arm64/booting.txt.  One can (and people have)
used bootm on aarch64 for "uImage" style kernels and FIT kernels, and I
would see being able to boot an aarch64 Android image with bootm as the
way to go forward.  The analogy would be that we use bootm for Android
on arm not bootz.  Thanks!
