# ubuntu-drivers-common custom detect plugin for arm GLES drivers
#
# (C) 2012 Canonical Ltd.
# Author: Oliver Grawert <ogra@ubuntu.com>
#
# This plugin detects GLES driver packages based on pattern matching
# against the "Hardware" line in /proc/cpuinfo.
#
# To add a new SoC, simply insert a line into the db variable with the
# following format:
#
# '<Pattern from your cpuinfo output>': '<Name of the driver package>',
#
