+// DV half of the lowRISC vendoring split. This config shares its target_dir

+// config vendors only the DV subtrees. The two halves are pinned to
+// independent upstream revisions via their separate lock files.
+//
+// Run order matters: vendor the DD config first, then this DV config. A DD run
+// deletes each ip/<block> directory (including its dv/ subdir) before
+// re-importing, so running the DD vendor after the DV vendor wipes the DV
+// content until this DV vendor is re-run. util/artefacts.py runs both in this
+// order before a single dirty-check.
