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
