This is pretty tricky. I'd use a python function inside your recipe.
You can get the layers like this:
layers = (bb.data.getVar("BBLAYERS", d, 1) or "").split()
Then if you have a look at the metadata_scm.bbclass, you can use some of
the functions in there:
base_get_metadata_git_branch
base_get_metadata_git_revision
Add some logic and you should be able to pull the revision information
you care about out of that data.
Cheers,
Stephano
