I don't know the hardware, but this patch is very strange. Does it
really work?
Maybe it should just change the loop to:
while ( ctx->transmitting && XUartLite_IsTransmitEmpty( ctx->address
) ) {
rtems_termios_dequeue_characters( tty, 1 );
}
When the transmit register is empty, you can dequeue the transmitted
char from the Termios transmit queue.
