It *is* checked in. It was checked in on the 17th of September.

Yes in principle, although I would like to see the quality of some
future patches before granting you write access to the repository. But
you are right, I have not updated the MAINTAINERS file, so I will do
that now.

Hi Nick,
Do you have any comment on Score patch?
I wanna know when you will check Score patch in to binutils mainline
source.
Do you agree to grant me the maintainer of target Score?
Thanks your time.
