While this paper directly applies to the Galaxy S6 (SM-G920F) and the Galaxy S7 Edge (SM-G935F) witch uses Exynos System On a Chip, some of its findings seem to be directly applicable to the devices supported by Replicant.

The most interesting part is the analysis of some of the bootloader environment variables:
14
* It analyzes some variables that accessible through the UART. We already have "documentation explained how to access such variables":https://redmine.replicant.us/projects/replicant/wiki/MidasBootloader#Changing-the-kernel-commandline-arguments but many variables aren't documented in the Replicant documentation.

* It also analyzed some variables present in the adv-env.img file inside the PARAM tarball filesystem. That information has already been used in the #2094 bug.
