+ * The main difference with fdtdec_setup() is that it returns if the fdt has
+ * changed because a better match has been found.
+ * This is typically used for boards that rely on a DM driver to detect the
+ * board type. This function sould be called by the board code after the stuff
+ * needed by board_fit_config_name_match() to operate porperly is available.
+ * If this functions signals that a rescan is necessary, the board code must
+ * unbind all the drivers using dm_uninit() and then rescan the DT with
+ * dm_init_and_scan().
+ *
+ * @param rescan Returns a flag indicating that fdt has changed and rescanning
+ *               the fdt is required
+ *
+ * @return 0 if OK, -ve on error
