sandbox: Allow the console to work earlier

2014-01-09T00:24:50+00:00

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

2012-12-13T18:46:56+00:00

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)

env: Refactor do_apply to a flag

2012-12-13T18:46:54+00:00

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

console: Enable function to display console info

2012-12-11T20:18:12+00:00

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.

Revert "Add board_pre_console_putc to deal with early console output"

2012-03-23T20:27:32+00:00

This reverts commit 295d3942b806552503243f5cfb36aec6f1b5a9bf.

It turns that this really doesn't work very nicely. Instead we should
have a pre-console panic function so that we know that further execution
is impossible and we don't need to worry about trampling on UARTs, etc.

Make printf and vprintf safe from buffer overruns

2011-12-17T22:34:43+00:00

From: Sonny Rao 

utilize the added vscnprintf functions to avoid buffer overruns
The implementation is fairly dumb in that it doesn't detect
that the buffer is too small, but at least will not cause crashes.

Add board_pre_console_putc to deal with early console output

2011-12-09T13:44:22+00:00

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.
