Since this patch was applied, I see a warning message
  WARNING: no status info for 'socfpga_socrates'
  WARNING: no maintainers for 'socfpga_socrates'
when I run tools/genboardscfg.py


I think you should add the maintainership info
  F:   configs/socfpga_socrates_defconfig
to somewhere of MAINTAINERS to suppress the warning message.
