+# This file defines the keys and certificates that must be created to establish
+# a Chain of Trust for the DDR FW. These definitions include the
+# command line options passed to the cert_create and fiptool commands for DDR FW.
+# A DDR FW key is used for signing the DDR Firmware. The DDR key is authenticated
+# by the Trusted World Key. Two content certificates are created:
+# For DDR RDIMM Images [ signed by DDR FW Key]
+# For DDR UDIMM Images [ signed by DDR FW Key]
+#
+# Expected environment:
+#
+#   BUILD_PLAT: output directory

+# Build options added by this file:

+#   KEY_ALG
+#   KEY_SIZE
+#   TRUSTED_WORLD_KEY
+#   NON_TRUSTED_WORLD_KEY
