The .axf file is something traditionally called ARM eXecutable Format,
which these days it's just an ELF format that the model can load
directly. The above code contains the pre-Linux boot initialisation, the
kernel Image (uncompressed, doesn't have a decompressor) and possibly a
filesystem, unless you use the --block-device model option. To get the
boot wrapper, just clone this:
git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/boot-wrapper-aarch64.git
The README and Makefile should be enough to get you started.

I think that's the library that contains the actual software model.
