25  * serial_null() - Void registration routine of a serial driver
27  * This routine implements a void registration routine of a serial
129  * serial_register() - Register serial driver with serial driver core
130  * @dev:	Pointer to the serial driver structure
132  * This function registers the serial driver supplied via @dev with
133  * serial driver core, thus making U-Boot aware of it and making it
162  * serial_initialize() - Register all compiled-in serial port drivers
164  * This function registers all serial port drivers that are compiled
165  * into the U-Boot binary with the serial core, thus making them
167  * serial port to the serial core. That serial port is then used as a
227  * serial_stdio_init() - Register serial ports with STDIO core
229  * This function generates a proxy driver for each serial port driver.
231  * serial drivers available as STDIO devices.
259  * serial_assign() - Select the serial output device by name
260  * @name:	Name of the serial driver to be used as default output
262  * This function configures the serial output multiplexing by
263  * selecting which serial device will be used as default. In case
264  * the STDIO "serial" device is selected as stdin/stdout/stderr,
265  * the serial device previously configured by this function will be
285  * serial_reinit_all() - Reinitialize all compiled-in serial ports
287  * This function reinitializes all serial ports that are compiled
299  * get_current() - Return pointer to currently selected serial port
301  * This function returns a pointer to currently selected serial port.
302  * The currently selected serial port is altered by serial_assign()
305  * In case this function is called before relocation or before any serial
307  * determine the serial port. Otherwise, the configured serial port is
310  * Returns pointer to the currently selected serial port on success,
338  * serial_init() - Initialize currently selected serial port
340  * This function initializes the currently selected serial port. This
354  * serial_setbrg() - Configure baud-rate of currently selected serial port
357  * serial port. The baud-rate is retrieved from global data within
358  * the serial port driver. This function uses the get_current() call
369  * serial_getc() - Read character from currently selected serial port
371  * This function retrieves a character from currently selected serial
372  * port. In case there is no character waiting on the serial port,
385  * serial_tstc() - Test if data is available on currently selected serial port
388  * currently selected serial port. This function never blocks. This
400  * serial_putc() - Output character via currently selected serial port
401  * @c:	Single character to be output from the serial port.
403  * This function outputs a character via currently selected serial
404  * port. This character is passed to the serial port driver responsible
416  * serial_puts() - Output string via currently selected serial port
417  * @s:	Zero-terminated string to be output from the serial port.
420  * selected serial port. This function behaves as an accelerator
435  * @s:	Zero-terminated string to be output from the serial port.
456  * uart_post_test() - Test the currently selected serial port using POST
459  * Do a loopback test of the currently selected serial port. This
461  * The serial port is first configured into loopback mode and then
474 	/* Save current serial state */  in uart_post_test()
506 			 *  - serial program reacting to sequences and sending  in uart_post_test()
508 			 *  - most serial drivers add in extra chars (like \r\n)  in uart_post_test()
540 	/* Restore previous serial state */  in uart_post_test()
