    stm32/machine_uart: Implement uart.flush() and uart.txdone(). · 8ea6fefc
    robert-hh authored 
    Since uart.write() of the STM32 port waits until all bytes have
been sent, uart.flush() and uart.txdone() are implemented as empty
functions to provide API consistency.

uart.flush()

flush() will always return immediately.

ret = uart.txdone()

uart.txdone() will always return True.
