The number of boards has been raising in last months and, as result,
the maintainance effort. It is quite difficult to keep all boards in
good shape without sharing the maintenance load among several people.
A maintainer field is now in machine configuration file of
meta-fsl-arm and meta-fsl-arm-extra and this script prints that
information.
