Approved, but before merging, I suggest you change the title of the PR as it does not seem to match and the commit message will be that title.

Turns out these are not needed. @Gmerold, should I be deleting all these files, or are some stiff used?

Not sure what do you mean by all these files, as I only see the removal of one variable. And that one is unused indeed and should be removed.

I meant to ask if any of the files in this directory were being used or are they all deprecated now?

Oh, ok. Yes, these files are very much being used. The official SD-Core root module doesn't contain the router and the gnbsim, both of which are needed for the tests. This module here combines all the required pieces.
