+ * Name:  stm32_pullup
+ *
+ * Description:
+ *   If USB is supported and the board supports a pullup via GPIO (for USB software
+ *   connect and disconnect), then the board software must provide stm32_pullup.
+ *   See include/nuttx/usbdev.h for additional description of this method.
+ *   Alternatively, if no pull-up GPIO the following EXTERN can be redefined to be
+ *   NULL.
