When I suggested cscope I did so in the (probably implicit) context of navigating
the C and C++ code that makes up OpenBMC. cscope does not support navigating
bitbake recipes as far as I'm aware. Your best tools there are `git ls-files` and
`git grep`. Note that the C and C++ code all resides in separate repos that are
pointed to by the bitbake recipes.
I hope that clarifies, sorry for any confusion.
