Nico Huber be5492aec0 Add minimal GNAT run time system (RTS)
Add a stripped-down version of libgnat. This is somehow comparable to
libgcc but for Ada programs. It's licensed under GPLv3 but with the
runtime library exception. So it's totally fine to link it with our
GPLv2 code and keep it under GPLv2.

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 '*'

conditions aren't met, fall back to using the find command.
- Wrap the command so it's easier to read.

Currently the Kconfig test is triggered by removing the board

This checks to see if taint mode is enabled, and untaints the path
if it is.  All external tools (git & grep) must be in
/bin, /usr/bin, or /usr/local/bin.
This also removes the check for unused kconfig files if taint mode
is enabled.

Martin Roth 6966759edb util/lint: Fix linter for old license headers
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.

- Split the script up to make it easier to update and read.
- Check for multiple different license strings. Not all files are GPL
licensed.
- Don't validate 0 length files
- Update list of files to exclude from the license header check.
- Add command line option to set directories to check

- Add stable version to check a few directories that are fixed.  This
just calls the non-stable version with the directories to check.

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
