[coreboot] coreboot-checkpath ?

Folks,
I have a number of patches failing build-bot step with an indication 
that coreboot-checkpath should be run.

How do I run this check locally?

Is this installed as part of 'make gitconfig' which I can't run on my 
older git install?

Can I download this script(?)

Any suggestions on how best to clear coreboot-checkpath on my patches is 
appreciated.
Cheers,
T.mike
