When running multiple tests, e.g. by using unit-tests target, it is hard
to differentiate, which output comes from which file and/or
configuration. This patch makes the output easier to analyze and
understand by using new wrapper macro cb_run_group_tests(). This macro
uses __TEST_NAME__ value (containing test path and Makefile test name)
as a group name when calling cmocka group runner.
Example:
Test path: tests/lib/
Makefile test name: cbmem_stage_cache-test
Test group array name: tests
Result: tests/lib/cbmem_stage_cache-test(tests)

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.

GENMASK(high, low) sets bits from `high` to `low` (inclusive) to 1. For

calling a, --wrap=a does nothing to that call.
Instead, use objcopy to mark a weak and global so it can be overridden

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

This patch changes the memlayout macro infrastructure so that the size
of a region "xxx" (i.e. the distance between the symbols _xxx and _exxx)
is stored in a separate _xxx_size symbol. This has the advantage that
region sizes can be used inside static initializers, and also saves an
extra subtraction at runtime. Since linker symbols can only be treated
as addresses (not as raw integers) by C, retain the REGION_SIZE()
accessor macro to hide the necessary typecast.

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.

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.

This change updates the definition of config_of_soc() to a macro that
expands to __pci_0_00_0_config instead of accessing the config
structure by referencing the struct device. This allows linker to
optimize out unused portions of the device tree from early stages.
With this change, bootblock .text section size drops as follows:

Older GCCs don't support _Static_assert without a message string as the
second argument. AFAICT _Static_assert with two arguments is in C11 but
omitting the message argument is an extension.
The tests appear to be built with the system gcc rather than our
crossgcc so that's probably why this was not cought by CI.

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.

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).

<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.
