+Subject: [PATCH] dpa_app: allow XML config paths to be overridden by env
+
+Keep the vendor default XML paths, but allow deployments to override them
+without patching the binary or placing board-specific XML files directly
+under /etc.
+
+Supported environment variables:
+
+  CDX_CFG_FILE
+  CDX_PCD_FILE
+  CDX_PDL_FILE
+  CDX_SP_FILE
+
+This is useful for monok8s/OpenRC integration where board-specific DPA
+configuration can live under a managed config directory.
