* Fix console functions for U-Boot APISimon Glass2014-12-08-4/+4
| | | | | | | | | | | | | | | | | | | | | Commit 709ea54 made a subtle change to the way the U-Boot API jump table is set up. So at present putc(), getc(), tstc() and puts() do not work correctly from functions that use the U-Boot API. Previously these were set to the stdio functions, but these now take a parameter specifying which stdio device to use. Instead, we should change them to use the global functions which do not have a parameter. This is a slight change in behaviour. The functions will now output to all selected stdio devices - for example putc() will output a character to all devices selected by stdout. However in most cases there is only one, and it isn't necessarily incorrect behaviour anyway. The API version is not changed since it is compatible with what was there before.

* sandbox: Disable Ctrl-CSimon Glass2014-09-24-0/+3
| | | | | | | | This is not supported properly on sandbox, and interferes with running tests, since when a test script is piped in, some commands will call ctrlc() which will drop characters from the test script. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add a flag indicating when the serial console is readySimon Glass2014-07-23-2/+2
| | | | | | | | | | 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>
* console: Remove vprintf() optimisation for sandboxSimon Glass2014-07-23-1/+1
| | | | | | | | | | | | If the console is not present, we try to reduce overhead by stopping any output in vprintf(), before it gets to putc(). This is of dubious merit in general, but in the case of sandbox it is incorrect since we have a fallback console which reports errors very early in U-Boot. If this is defeated U-Boot can hang or exit with no indication of what is wrong. Remove the optimisation for sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>
* stdio: Pass device pointer to stdio methodsSimon Glass2014-07-23-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* sandbox: Allow the console to work earlierSimon Glass2014-01-08-1/+15
| | | | | | | | | | | | | With sandbox, errors and problems may be reported before console_init_f() is executed. For example, an argument may not parse correctly or U-Boot may panic(). At present this output is swallowed so there is no indication what is going wrong. Adjust the console to deal with a very early sandbox setup, by detecting that there is no global_data yet, and calling os functions in that case.

* console: Enable function to display console infoSimon Glass2012-12-11-2/+4
| | | | | | | | | | | The CONFIG_SYS_CONSOLE_INFO_QUIET option should suppress the console information, but allow boards to display it later if required. Adjust the code to support this. This is used to avoid printing the information while the LCD display is not ready, since it only becomes ready when stdio init is complete. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | This reverts commit 295d3942b806552503243f5cfb36aec6f1b5a9bf. It turns that this really doesn't work very nicely.

* Add board_pre_console_putc to deal with early console outputSimon Glass2011-12-09-1/+9
| | | | | | | | | | | | | | | | This patch adds support for console output before the console is inited. The main purpose of this is to deal with a very early panic() which would otherwise cause a silent hang. A new board_pre_console_putc() function is added to the board API. If provided by the board it will be called in the event of console output before the console is ready. This function should turn on all UARTs and spray the character out if it possibly can. The feature is controlled by a new CONFIG_PRE_CONSOLE_PUTC option. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Graeme Russ <graeme.russ@gmail.com>
* console: Implement pre-console bufferGraeme Russ2011-10-05-2/+41
| | | | | | | | | | | | | Allow redirection of console output prior to console initialisation to a temporary buffer. To enable this functionality, the board (or arch) must define: - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes) The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes Any earlier characters are silently dropped.
* console: Squelch pre-console output in console functionsGraeme Russ2011-10-01-0/+18
| | | | | | | | | | There are some locations in the code which anticipate printf() being called before the console is ready by squelching printf() on gd->have_console. Move this squelching into printf(), vprintf(), puts() and putc(). Also make tstc() and getc() return 0 if console is not yet initialised Signed-off-by: Graeme Russ <graeme.russ@gmail.com> Tested-by: Simon Glass <sjg@chromium.org>

* console.c: fix problem with splashimageAnatolij Gustschin2010-03-21-3/+7
| | | | | | | | | | | | | | | | | | If a board uses cfb_console driver and splash image and also defines CONFIG_SILENT_CONSOLE, the user is locked out even if "silent" is not set. It is not possible to get any output, neither on vga console device nor on serial console after redirecting the output to the serial console, since the GD_FLG_SILENT flag remains set. Fix the problem by redirecting the output from frame buffer to serial console if splashimage is used. Only suppress the output if "silent" environment variable was set and don't set the GD_FLG_SILENT flag arbitrarily. Signed-off-by: Anatolij Gustschin <agust@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Jennejohn2008-12-07-1/+155
| | | | | | | | | | | | | | | | | | | | | | | | 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.
