This script generates the rough format for the release notes, and will
add new commits to the top of an existing release notes text file. At
that point, a lot still needs to be done by hand - deciding which
commits deserve to be in the release notes, and which don't.
When updating the existing release notes, The updates are just added
to the top of the file, and need to be placed manually. This just
helps prevent missed commits.
When editing the release notes, don't delete or modify the commit id
lines after they've been classified - Just move them to the bottom of
the file until the notes are ready to publish. This keeps those commits
from re-appearing at the top of the file the next time the script is run
to update the notes.

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:

With the previous ELF stage extract support the resulting
ELF files wouldn't handle rmodules correctly in that the
rmodule header as well as the relocations were a part of
the program proper. Instead, try an initial pass at
converting the stage as if it was an rmodule first. If it
doesn't work fall back on the normal ELF extraction.
TEST=Pulled an rmodule out of Chrome OS shellball. Manually
matched up the metadata and relocations.

In order to convert rmodules back into ELF files one needs
to add in the relocations so they can be converted back to
rmodules. Because of that requirement symbol tables need
to be present because the relocations reference the symbols.
Additionally, symbol tables reference a string table for the
symbol names. Provide the necessary support for adding all
of those things to an ELF writer.
TEST=Extracted rmodule from a cbfs and compared with the
source ELF file. Confirmed relocations and code sizes
are correct.

Instead of creating a loadable segment for each section with
SHF_ALLOC flag merge those sections into a single program
segment. This makes more tidy readelf, but it also allows
one to extract an rmodule into an ELF and turn it back into
an rmodule.
TEST=Extracted both regular stages and rmodule stages. Compared
against original ELF files prior to cbfs insert.

Instead of dumping the raw stage data when cbfstool
extract is used on stage create an equivalent ELF file.
Because there isn't a lot of information within a stage
file only a rudimentary ELF can be created.
Note: this will break Chrome OS' current usage of extract
since the file is no longer a cbfs_stage. It's an ELF file.
TEST=Extracted romstage from rom.

In order to prepare allowing for one to extract a stage
into an ELF file provide an optional -m ARCH option. This
allows one to indicate to cbfstool what architecture type
the ELF file should be in.
Longer term each stage and payload will have an attribute
associated with it which indicates the attributes of
the executable.

In order to actually do something useful with the
resulting file after being extracted decompress stage
files' content. That way one can interrogate the
resulting file w/o having to decompress on the fly.
Note: This change will cause an unexpected change to
Chrome OS devices which package up individual stage
files in the RW slots w/o using cbfs. The result will
be that compressed stages are now decompressed.
Longer term is to turn these files into proper ELF
files on the way out.

This utility links in coreboot code, and has been broken for a while
again after removing some hacks from coreboot. I hadn't realized how
bad it was broken last time, and since most of this stuff is still
in a pretty bad shape, I decided to throw all of the changes together.

Currently cbfs stage files that are compressed do not have
the decompressed size readily available. Therefore there's
no good way to know actual size of data after it is
decompressed. Optionally return the decompressed data size
if requested.

Add minimal Makefile based on cbmem’s Makefile.
The make target `junit.xml` is removed as this is handled differently
since commit de9adebb (Add junit.xml code to top Makefile.inc instead of
utils).
Also the `junit.xml` is removed in the make target `clean`.
Additionally, the make target `distclean` is added, as the current
junit.xml code in the top `Makefile.inc` requires that.

This patch fixes compilation of cbfstool on Cygwin.
As reported in http://review.coreboot.org/#/c/10027
cbfstool on Cygwin likes to be compiled with -D_GNU_SOURCE.
That patch was abandoned because it would unwantedly turn on
more GNU extensions. Instead of doing that, only enable the
define on Cygwin, switch to -std=gnu99 instead of -std=c99 to
make fileno and strdup actually available.
A MINGW32 check that was forgotten in Makefile was copied over
from Makefile.inc to keep the two files in sync.
This patch has no impact on non-Windows builds.
