+# Class to provide a possibility to re-use names of Security Controller (SECO)
+# Firmware files, which are required by certain derivatives on i.MX8 family.
+#
+# SECO Firmware names are used by imx-boot and imx-seco recipes, therefore
+# their respective definitions are moved into a separate class, which is
+# inherited by both recipes.
+#
+# Currently, only 'mx8m' family does not require SECO FW to be provided in the
+# target image, therefore as a first step - the machine override is verified
+# if it matches, and then derivative is taken.
+#
+# NOTE: SECO_FIRMWARE_NAME defaults to empty string, and is verified against
+# the family first. If a derivative in the family does not have a firmware name
+# set in this class - recipe parsing is stopped.
+# This behavior ensures that derivatives which requires SECO Firmware to be
+# present in the image file have it properly defined.
