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.

This fixes at least one kconfig_lint warning.

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.

- Check that selected symbols are type bool
- Check that selected symbols aren't created inside a choice
- Check that symbols created inside a choice aren't created
outside of a choice as well.

Martin Roth b6acc3071f kconfig_lint: Fix check_is_enabled for 2 symbols on the same line
The previous code would miss the first of two IS_ENABLED(CONFIG_symbol)
sequences on a line.  This patch saves the rest of the line and loops
to check any other entries on the same line of text.

Patrick Georgi a73b93157f tree: drop last paragraph of GPL copyright header
It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.

This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

Martin Roth bcaaad1c55 lint: Add Kconfig / Kconfig symbol lint tool
This is a tool to help identify issues in coreboot's Kconfig structure
and in how the Kconfig symbols are used in the coreboot codebase.

It identifies a number of issues:
- #ifdef used on Kconfig symbol of type bool, hex, or int.  These are
always defined.
- #define CONFIG_ in the coreboot code - these should be reserved
for Kconfig symbols.
- Redefinition of Kconfig symbols in the code.
- Use of IS_ENABLED() on non-bool kconfig symbols.
- Use of IS_ENABLED() on values that are not kconfig symbols.
- Attempts to find default values that will not set anything
because of earlier default settings.  This needs to be expanded
significantly.
- Kconfig expressions using symbols which are not defined.
- Kconfig symbols that are defined but not used anywhere in the
Kconfig structure or coreboot code.
- Kconfig keywords used incorrectly.
- Whitespace issues
- Kconfig 'source' keyword issues
-- sourcing non-existant directories
-- sourcing Kconfig files multiple times
-- sourcing non-existent files
-- Kconfig files in the codebase that are never sourced

Additionally, it can be used to help debug the Kconfig tree
by putting all the files together into a single file with
their source locations listed.

Run from the coreboot directory:
util/lint/kconfig_lint
