+# This file is the device-specific product definition file for
+# crespo. It lists all the overlays, files, modules and properties
+# that are specific to this hardware: i.e. those are device-specific
+# drivers, configuration files, settings, etc...
+
+# Note that crespo is not a fully open device. Some of the drivers
+# aren't publicly available in all circumstances, which means that some
+# of the hardware capabilities aren't present in builds where those
+# drivers aren't available. Such cases are handled by having this file
+# separated into two halves: this half here contains the parts that
+# are available to everyone, while another half in the vendor/ hierarchy
+# augments that set with the parts that are only relevant when all the
+# associated drivers are available. Aspects that are irrelevant but
+# harmless in no-driver builds should be kept here for simplicity and
+# transparency. There are two variants of the half that deals with
+# the unavailable drivers: one is directly checked into the unreleased
+# vendor tree and is used by engineers who have access to it. The other
+# is generated by setup-makefile.sh in the same directory as this files,
+# and is used by people who have access to binary versions of the drivers
+# but not to the original vendor tree. Be sure to update both.
