can set breakpoint to `arm_pl011_write_polled`
list file shows :
```
426     int arm_pl011_read_polled(rtems_termios_device_context *base)
427     {
428       volatile arm_pl011_uart *regs = arm_pl011_get_regs(base);
429
430       if (arm_pl011_is_rxfifo_empty(&regs->base)) {
431         return -1;
432       } else {
433         return arm_pl011_read_char(&regs->base);
434       }
435     }
436
437     void arm_pl011_write_polled(rtems_termios_device_context *base, char c)
438     {
439       volatile arm_pl011_uart *regs = arm_pl011_get_regs(base);
440
441       /* Wait until TXFIFO has space */
442       while (arm_pl011_is_txfifo_full(&regs->base)) {
443         /* Wait */
444       }
