Martin Roth ab273d3f16 kconfig_lint: More updates for excluded files
- All of the symbols are in the .config, so if .config is include in
the search all of the symbols are always found.
- There are now some Kconfig symbols in the Documentation directory,
so that needs to be excluded.
- 3rdparty has lots of Kconfig symbols that are unrelated to what
is being searched for.

Martin Roth 78f73353a3 util/lint/lint: Show lint script output as it's running
The checkpatch script takes a really long time to run, and when the
output is buffered to wait until it's finished, it's hard to tell if
the script is actually doing anything.

Instead, use tee to log the output and display it at the same time.

Martin Roth 8bc8be4d0e util/lint/kconfig_lint: change warning levels and text
- Add an exception for MAINBOARD_POWER_ON_AFTER_POWER_FAIL when checking
- With those exceptions set, we don't have anymore #define or #ifdef
warnings, so turn them to errors so no more can be pushed.
- Change the definition of an unused symbol from a warning to a note.
There are times when unused symbols are expected.
- Upgrade the warning for loading Kconfig files multiple times from
a warning to an error.

Martin Roth f790672f2d util/lint: Find unsigned variables with no length specified
The coding guidelines say that all objects should have fully
qualified types (unsigned int instead of unsigned).

This script finds violations of that rule.

Steps for the filter:
1) Find all lines in the coreboot tree that have the word 'unsigned'
followed by a space.
2) Exclude directories that aren't in the include list or
are specifically excluded.
3) Exclude files that aren't specifically included.
4) Filter out legimitate uses 'unsigned int' or 'unsigned long' for
example.
5) Filter out lines that begin with '/*' or '*'

would overwrite the previous.
- Record the menu each prompt is in.

Martin Roth 08ee1cfafc kconfig_lint: Add warning if tristate type is used in coreboot
Although there's no reason we COULDN'T use tristate types, we haven't
up to this point.  If there's a good reason to use them in the future,
this check can be removed.

Martin Roth 819e67242f kconfig_lint: merge 'git grep' and 'grep' exclude dir and files
The code had originally been using standard grep to look through the
coreboot tree for Kconfig symbols.  When this was switched to git grep,
the --exclude-dir options didn't work, and nothing was added to exclude
the directories that shouldn't be searched for symbols.  This resulted
in invalid warnings as it searched directories that had Kconfig symbols
for other projects.

This merges the exclusion list for both the regular and git versions
of grep for consistent behavior.

Martin Roth 6bfbf1c66f kconfig_lint: Exclude some Kconfig symbols from unused symbol checks
The configuration that coreboot uses for setting selected symbols
typically involves a structure like this:
config BLEH_SPECIFIC_OPTIONS
def_bool y
select SYMBOL

This leads to an an extra kconfig symbol BLEH_SPECIFIC_OPTIONS
that is never referenced by anything else, generating a warning.

Since this is currently the construct that coreboot uses, filter it
out of the warnings for now.

Somehow I lost a $ on headerlist between when I tested the script
and when I submitted it, turning headerlist into plain text instead
of a variable name.  This makes the test always pass.
- Fix variable bug.
- exclude this script from the check.
- update test for empty HEADER_DIRS variable.
