+Subject: [PATCH] rcar_gen3: plat: Do not panic on unrecognized boards
+
+Replace the panic in bl2_populate_compatible_string with just putting
+"unknown" into the compatible string for the FDT. This allows us to
+boot on the AGL reference hardware where the board type seems
+unavailable.
+
+Upstream-Status: Inappropriate [board specific usecase]
