Martin Roth 96edc100c0 tests: Add option for debug symbols & no optimization
To make it easier to build the tests with debug symbols, add a check for
the "GDB_DEBUG" environment variable.  If set, build with -g and -Og to
enable the symbols and disable optimization.

Julius Werner c90d406008 tests: Disable -Wmain-return-type for clang
Unit tests fail on clang 13.0 because Cmocka's main() function is
declared with return type int, but through some of our chain-include
games it sometimes gets coreboot's main_decl.h which declares the
function as void. Compilers have traditionally always been very
laissez-faire about the signature of the main function, but it seems
that clang has been getting more strict by default recently. Explicitly
disable the related warning to shut it up.

Jakub Czapiga 4d9694e6bc tests: Fix JUNIT_OUTPUT=y to write to files instead of stderr
CB:57144 broke JUNIT_OUTPUT=y, and unit-tests were writing to stderr
instead of selected XML files, because test name used for XML file
creation contains test path. Build system did not create necessary
directiories, which CMocka required to create output files.
This commit fixes writing to XML files with JUNIT_OUTPUT=y, but had to
sacrifice path in test name, as it was causing a lot of problems
(because CMocka does not know, how to write multiple test groups to one
XML file, so it uses test group name [here __TEST_NAME__(test_group)] as
part of output filename).
Example:
 Test: tests/lib/rtc-test
 Output file:
 `build/tests/junit-tests_lib_rtc-test(tests).xml

Julius Werner ab91407735 tests: Fix function mocking for clang
clang seems to like to do some aggressive optimizations that break our
approach of mocking functions for test by using objcopy to turn them
weak after the fact on individual compiled object files. For example, in
CB:56601 the function cbfs_get_boot_device() is mocked this way. When
compiling the cbfs_boot_lookup() function in src/lib/cbfs.c with clang,
it will generate a normal callq instruction to a relocation for
cbfs_boot_lookup(), which can then later be pointed to the mocked
version of that function. However, it will also somehow infer that the
version of cbfs_boot_lookup() in that file can only ever return a
pointer to the static local `ro` variable (because CONFIG_VBOOT is
disabled in the environment for that particular test), and instead
generate instructions that directly load the address of a relocation for
that variable into %rdi for the following call to cbfs_lookup(), rather
than using the real function return value. (Why it would do that is
anyone's guess because this seems unlikely to be faster than just moving
the function return value from %rax into %rdi like a normal compiler.)

Long story short, this optimization breaks our tests because
cbfs_lookup() will be called with the wrong pointer. clang doesn't
provide many options to disable individual optimizations, so the only
solution seems to be to make clang aware that the function is weak
during the compilation stage already, so it can be aware that it may get
replaced. This patch implements that by marking the mocked functions
weak via #pragma weak lines in the per-test autogenerated config header.

 - one to remove everything that wasn't our own code, leaving only

 - one to copy in Linux 5.13's scripts/kconfig and adapt Makefile.inc
   to make the original Makefile work again.
 - adapt abuild to use olddefconfig, simplifying matters.
 - apply patches in util/kconfig/patches.
 - Some more adaptations to the libpayload build system.

The patches are now in util/kconfig/patches/, reverse applying them
should lead to a util/kconfig/ tree that contains exactly the Linux
version + our own 5 files.

Patrick Georgi ce55ca2fca tests: Rework mocking facility
Using the linker's --wrap feature has the downside that it only covers
references across object files: If foo.c defines a() and b(), with b
calling a, --wrap=a does nothing to that call.

Instead, use objcopy to mark a weak and global so it can be overridden
by another implementation, but only for files originating in src/.

That way mocks - implemented in tests/ - become the source of truth.

TEST=Had such an issue with get_log_level() in a follow-up commit, and
the mock now takes over. Also, all existing unit tests still pass.

Julius Werner 84446e6e54 rmodtool: Make memlayout symbols absolute and do not relocate them
Memlayout is a mechanism to define memory areas outside the normal
program segment constructed by the linker. Therefore, it generally
doesn't make sense to relocate memlayout symbols when the program is
relocated. They tend to refer to things that are always in one specific
spot, independent of where the program is loaded.

This hasn't really hurt us in the past because the use case we have for
rmodules (ramstage on x86) just happens to not really need to refer to
any memlayout-defined areas at the moment. But that use case may come up
in the future so it's still worth fixing.

This patch declares all memlayout-defined symbols as ABSOLUTE() in the
linker, which is then reflected in the symbol table of the generated
ELF. We can then use that distinction to have rmodtool skip them when
generating the relocation table for an rmodule. (Also rearrange rmodtool
a little to make the primary string table more easily accessible to the
rest of the code, so we can refer to symbol names in debug output.)

A similar problem can come up with userspace unit tests, but we cannot
modify the userspace relocation toolchain (and for unfortunate
historical reasons, it tries to relocate even absolute symbols). We'll
just disable PIC and make those binaries fully static to avoid that
issue.

Julius Werner e54d784d02 tests: Build tests with -Wno-inline-asm
Clang doesn't seem to get along with some of the symbol magic we use for
memlayout and throws -Winline-asm warnings. Since we want to be
compatible with as many host compilers as possible (within reason),
let's disable that warning.

Julius Werner 1e14de8bda tests: Add some basic warnings and fix resulting issues
The current test framework builds the test code without any warnings at
all, which isn't great -- we have already slipped in some cases of
non-void functions not returning a defined value, for example. It would
likely be overkill to try to use all the same warnings we use for normal
coreboot code (e.g. some stuff like -Wmissing-prototypes makes cmocka's
__wrap_xxx() mock functions unnecessarily cumbersome to work with, and
other things like -Wvla may be appropriate for firmware but is probably
too aggressive for some simple test code). Therefore, let's just add
some of the stuff that points out the most obvious errors.

So far, the semantics have been that run-unit-tests stopped at the first
test suite that failed. This hides useful signal in later tests, so
always run all tests and collect the result.

Jan Dabros 7f00dba33b tests: Build Cmocka from source
Relying on Cmocka packages, which are provided with different OS
distributions, may introduce some problems with setup environments
across developers (e.g. library version mismatch). Instead, let's build
Cmocka from source code, which is now added to git submodules as
3rdparty/cmocka.

Please note, that cmake tool is required for building Cmocka (thus also
coreboot unit tests).

Julius Werner 21744811bb tests: Add <tests/test.h> wrapper header and fix --gc-sections
<cmocka.h> requires a few standard headers to be explicitly included
before itself or it will throw compilation errors. Having to always
include these headers in the right order in every test is cumbersome.
Instead, this patch encapsulates the problem in a new <tests/test.h>
header that all tests should include (instead of <cmocka.h> directly).

Also fix --gc-sections in the test framework which needs to be passed
for linking, not for compiling.

Jan Dabros ef1c968374 tests: Add build subsystem for unit testing coreboot
Add a subsystem which will be used for writing, building and running
unit tests for different coreboot's modules. This work is built using
Cmocka unit testing framework. Description of what unit testing means
(for the author) and how unit testing framework evaluation was performed
may be found in Documentation/technotes/2020-03-unit-testing-coreboot.md

Makefiles structure is very similar to this used for building coreboot
images. Every directory has its own Makefile.inc were tests' names,
sources, subdirs and multiple other test-related attributes are defined
in form of variables.
