# @ECLASS-VARIABLE: EC_BOARDS
# @DESCRIPTION:
#  This class contains function that lists the name of embedded
#  controllers for a given system.
#  When found, the array EC_BOARDS is populated.
#  For example, for a falco machine, EC_BOARDS = [ "falco" ]
#  For samus, EC_BOARDS = [ "samus", "samus_pd" ]
#
#  The firmware for these ECs can be found in platform/ec/build

# Check for EAPI 4+
