Sounds like you are looking for the top (and possibly glob) magic
pathspec, e.g. in the source tree of Git itself, I can go a few
levels down into a random directory and get exactly the same listing
of two files whose name is "rerere.c" located in two directories:

    $ cd t/helper
    $ git ls-files --full-name ':(top,glob)**/rerere.c'
    builtin/rerere.c
    rerere.c

Look for magic pathspec in "git help glossary" to learn more.
