+# Apply overlays statically with fdtoverlay. This is a build time test that
+# the overlays can be applied successfully by fdtoverlay. This does not
+# guarantee that the overlays can be applied successfully at run time by
+# unittest, but it provides a bit of build time test coverage for those
+# who do not execute unittest.
+#
+# The overlays are applied on top of static_base_1.dtb and static_base_2.dtb to
+# create static_test_1.dtb and static_test_2.dtb. If fdtoverlay detects an
+# error than the kernel build will fail. static_test_1.dtb and
+# static_test_2.dtb are not consumed by unittest.

+# Some unittest overlays deliberately contain errors that unittest checks for.
+# These overlays will cause fdtoverlay to fail, and are thus not included
