* serial: Set up the 'priv' pointer when creating a serial deviceSimon Glass2014-09-10-0/+1
| | | | | | | | The stdio_dev structure has a private pointer for its creator, but it is not set up by the serial system. Set it to point to the serial device so that it can be found by code called by stdio. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add a flag indicating when the serial console is readySimon Glass2014-07-23-0/+1
| | | | | | | | | | For sandbox we have a fallback console which is used very early in U-Boot, before serial drivers are available. Rather than try to guess when to switch to the real console, add a flag so we can be sure. This makes sure that sandbox can always output a panic() message, for example, and avoids silent failure (which is very annoying in sandbox). Signed-off-by: Simon Glass <sjg@chromium.org>
* stdio: Pass device pointer to stdio methodsSimon Glass2014-07-23-6/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>

Implement function that does this behavior into common code, so others can make easy use of it. This function is called default_serial_puts() and it's sole purpose is to call putc() in loop on the whole string passed to it.

* serial: ns16550: Move serial registration from serial_initialize()Marek Vasut2012-10-15-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | Move the registration of eserialN_device ports from default serial_initialize() into driver specific function called from serial_initialize(). This slims down the serial_initialize() call to a bare tracker of all possible serial port registration routines in U-Boot. The newly implemented ns16550_serial_initialize() function, which is implemented inside of the ns16550 serial driver allows encapsulation of eserialN_device within the ns16550 serial driver itself. Also, remove the exports of eserialN_device from include/serial.h as they are no longer needed. This is simply because the implementation of default_serial_console() is wrapped into the ns16550 serial driver and the default console is picked by CONFIG_SERIAL<N> macro in config file.
