* serial: remove calls to serial_assign()Allen Martin2012-10-26-10/+0
| | | | | | | | | | | | | | Remove calls to serial_assign() that are failing now that it returns a proper error code. This calls were not actually doing anything because they passed the name of a stdio_dev when a serial_device name is exptectd.

* serial: Remove CONFIG_SERIAL_MULTI from remaining sourcesMarek Vasut2012-10-15-2/+0
| | | | | | | | | | | | Remove the parts depending either on disabled CONFIG_SERIAL_MULTI or ifdefs around CONFIG_SERIAL_MULTI parts since CONFIG_SERIAL_MULTI is now enabled by default.

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.

* IOMUX: Add console multiplexing support.Gary Jennejohn2008-12-07-0/+175
Modifications to support console multiplexing. This is controlled using CONFIG_SYS_CONSOLE_MUX in the board configuration file. This allows a user to specify multiple console devices in the environment with a command like this: setenv stdin serial,nc. As a result, the user can enter text on both the serial and netconsole interfaces. All devices - stdin, stdout and stderr - can be set in this manner. 1) common/iomux.c and include/iomux.h contain the environment setting implementation. 2) doc/README.iomux contains a somewhat more detailed description. 3) The implementation in (1) is called from common/cmd_nvedit.c to handle setenv and from common/console.c to handle initialization of input/output devices at boot time. 4) common/console.c also contains the code needed to poll multiple console devices for input and send output to all devices registered for output. 5) include/common.h includes iomux.h and common/Makefile generates iomux.o when CONFIG_SYS_CONSOLE_MUX is set.
