console: Always define the console-recording functions

2020-08-08T02:31:32+00:00

On boards without console recording these function are currently missing.
It is more convenient for them to be present but to return dummy values.
That way if we know that a test needs recording, we can check if it is
available, and skip the test if not, while avoiding #ifdefs.

Update the header file according and adjust console_record_reset_enable()
to return an error if recording is not available.

console: Add a way to output to serial only

2020-07-09T04:33:24+00:00

In the video drivers it is useful to print errors while debugging but
doing so risks an infinite loop as the debugging info itself may go
through the video drivers.

Add a new console function that prints information only to the serial
device, thus making it safe for use in debugging.

video: restore CONFIG_VIDCONSOLE_AS_LCD as boolean

2020-07-06T20:30:00+00:00

This patch restores CONFIG_VIDCONSOLE_AS_LCD as boolean
and introduce a separate sting as CONFIG_VIDCONSOLE_AS_NAME
to search this string in stdout used as videoconsole.

This patch avoid issue with board defconfig or code expecting
CONFIG_VIDCONSOLE_AS_LCD as boolean.

video: extend stdout video console work-around for 'vga'

2020-06-18T17:30:14+00:00

cfb_console driver uses 'vga' console name and we still have board
environments defining this name. Re-use existing DM_VIDEO work-
around for console name to support 'vga' name in stdout environment.

common/console.c: discard volatile

2020-02-13T15:10:50+00:00

Avoid errors of like

common/console.c: In function ‘console_record_reset’:
common/console.c:615:16: error: passing argument 1 of ‘membuff_purge’
discards ‘volatile’ qualifier from pointer target type
[-Werror=discarded-qualifiers]
  615 |  membuff_purge(&gd->console_out);
      |                ^~~~~~~~~~~~~~~~

by casting to non-volatile.

The volatile property stems from declarations like

arch/arm/include/asm/global_data.h:114:

But there is no need to treat gd->console_out and gd->console_in as
volatile in the context of common/console.c.

console: Add a function to read a line of the output / eof

2020-02-06T02:33:46+00:00

When recording the console output for testing it is useful to be able to
read the output a line at a time to check that the output is correct. Also
we need to check that we get to the end of the output.

Add a console function to return the next line and another to see how must
data is left.

common/console.c: Fix unused warning with console_doenv()

2019-11-07T03:54:28+00:00

Newer versions of LLVM-7 will provide an unused function warning over
console_doenv() in the case of SYS_CONSOLE_IS_IN_ENV not being enabled
as can be the case in SPL.  Add guards around this function.

env: Rename environment.h to env_internal.h

2019-08-11T23:27:31+00:00

This file contains lots of internal details about the environment. Most
code can include env.h instead, calling the functions there as needed.

Rename this file and add a comment at the top to indicate its internal
nature.
