The small loader tool is part of the Project Sandcastle by Corellium. It is a kind of flashing tool to run Android or Linux on Apple iPhones (iPhone 7). This tool is interesting to have for future developments in postmarketOS.
It builds and works fine. One issue is that there's no upstream release and I', pretty sure they won't do any releases since this was only published for demonstration purposes. Is it possible to package it as "git" or "unstable" release?
