26  * serial_null() - Void registration routine of a serial driver
28  * This routine implements a void registration routine of a serial
156  * serial_register() - Register serial driver with serial driver core
157  * @dev:	Pointer to the serial driver structure
159  * This function registers the serial driver supplied via @dev with
160  * serial driver core, thus making U-Boot aware of it and making it
189  * serial_initialize() - Register all compiled-in serial port drivers
191  * This function registers all serial port drivers that are compiled
192  * into the U-Boot binary with the serial core, thus making them
194  * serial port to the serial core. That serial port is then used as a
288  * serial_stdio_init() - Register serial ports with STDIO core
290  * This function generates a proxy driver for each serial port driver.
292  * serial drivers available as STDIO devices.
320  * serial_assign() - Select the serial output device by name
321  * @name:	Name of the serial driver to be used as default output
323  * This function configures the serial output multiplexing by
324  * selecting which serial device will be used as default. In case
325  * the STDIO "serial" device is selected as stdin/stdout/stderr,
326  * the serial device previously configured by this function will be
346  * serial_reinit_all() - Reinitialize all compiled-in serial ports
348  * This function reinitializes all serial ports that are compiled
360  * get_current() - Return pointer to currently selected serial port
362  * This function returns a pointer to currently selected serial port.
363  * The currently selected serial port is altered by serial_assign()
366  * In case this function is called before relocation or before any serial
368  * determine the serial port. Otherwise, the configured serial port is
371  * Returns pointer to the currently selected serial port on success,
399  * serial_init() - Initialize currently selected serial port
401  * This function initializes the currently selected serial port. This
415  * serial_setbrg() - Configure baud-rate of currently selected serial port
418  * serial port. The baud-rate is retrieved from global data within
419  * the serial port driver. This function uses the get_current() call
430  * serial_getc() - Read character from currently selected serial port
432  * This function retrieves a character from currently selected serial
433  * port. In case there is no character waiting on the serial port,
446  * serial_tstc() - Test if data is available on currently selected serial port
449  * currently selected serial port. This function never blocks. This
461  * serial_putc() - Output character via currently selected serial port
462  * @c:	Single character to be output from the serial port.
464  * This function outputs a character via currently selected serial
465  * port. This character is passed to the serial port driver responsible
477  * serial_puts() - Output string via currently selected serial port
478  * @s:	Zero-terminated string to be output from the serial port.
481  * selected serial port. This function behaves as an accelerator
496  * @s:	Zero-terminated string to be output from the serial port.
517  * uart_post_test() - Test the currently selected serial port using POST
520  * Do a loopback test of the currently selected serial port. This
522  * The serial port is first configured into loopback mode and then
535 	/* Save current serial state */  in uart_post_test()
567 			 *  - serial program reacting to sequences and sending  in uart_post_test()
569 			 *  - most serial drivers add in extra chars (like \r\n)  in uart_post_test()
601 	/* Restore previous serial state */  in uart_post_test()
