+ * fit_conf_get_node - get node offset for configuration of a given unit name
+ * @fit: pointer to the FIT format image header
+ * @conf_uname: configuration node unit name (NULL to use default)
+ *
+ * fit_conf_get_node() finds a configuration (within the '/configurations'
+ * parent node) of a provided unit name. If configuration is found its node
+ * offset is returned to the caller.
+ *
+ * When NULL is provided in second argument fit_conf_get_node() will search
+ * for a default configuration node instead. Default configuration node unit
+ * name is retrieved from FIT_DEFAULT_PROP property of the '/configurations'
+ * node.
+ *
+ * returns:
+ * configuration node offset when found (>=0)
+ * negative number on failure (FDT_ERR_* code)
