Patch Set 21:
> LGTM, except for the documentation. I think it's okay to get this in first and fix the docs later unless someone has a concern about that.

I will update the documentation after I create new util for making a payload.

I created new CL for adding new util tool that enables to make a payload for QEMU/AArch64. It's still WIP but you can see what I want to do. Could you take a look at it and tell me something wrong?
