# @DESCRIPTION:
# This class contains function that lists the name of embedded
# controllers for a given system.
# When found, the array EC_BOARDS is populated.
# It no ECs are known or build host tools, bds toolchain is defined.
# 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
# When not using unibuild, the first item of the array is always the main ec.
# Check for EAPI 4+
