Add a flag indicating when the serial console is ready

2014-07-23T13:07:25Z

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

console: Remove vprintf() optimisation for sandbox

2014-07-23T13:07:24Z

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

stdio: Pass device pointer to stdio methods

2014-07-23T13:07:23Z

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 Acked-by: Marek Vasut Reviewed-by: Marek Vasut

sandbox: Allow the console to work earlier

2014-01-09T00:24:50Z

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.

env: Add a silent env handler

2012-12-13T18:46:56Z

The silent variable now updates the global data flag anytime it is changed as well as after the env relocation (in case its value is different from the default env in such cases as NAND env) Signed-off-by: Joe Hershberger

env: Add a console env handler

Remove the hard-coded console handler and use a callback instead Signed-off-by: Joe Hershberger

env: Refactor do_apply to a flag

2012-12-13T18:46:54Z

Use a flag in hsearch_r for insert mode passed from import to allow the behavior be different based on use. Now that "do_check" is called for all imports, ensure console init is complete before updating the console on relocation import Signed-off-by: Joe Hershberger

console: Enable function to display console info

2012-12-11T20:18:12Z

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
