It looks like this socfpga_socrates board borrows most of the parts from socfpga_cyclone board,
so I think you can append your maintainership info to board/altera/socfpga/MAINTAINERS.

Perhaps it might be helpful to refer to board/sunxi/MAINTAINERS.
The core support of SUNXI boards are owned by Hans de Goede
and some additional files are maintained by other people.
