Arthur Heymans 2e7e2d978b coreboot_tables.c: Expose the ACPI RSDP
The ACPI RSDP can only be found in:
- legacy BIOS region
- via UEFI service

On some systems like ARM that legacy BIOS region is not an option, so
to avoid needing UEFI it makes sense to expose the RSDP via a coreboot
table entry.

This also adds the respective unit test.

Julius Werner 69cc557cfb commonlib/bsd: Remove cb_err_t
cb_err_t was meant to be used in place of `enum cb_err` in all
situations, but the choice to use a typedef here seems to be
controversial. We should not be arbitrarily using two different
identifiers for the same thing across the codebase, so since there are
no use cases for serializing enum cb_err at the moment (which would be
the primary reason to typedef a fixed-width integer instead), remove
cb_err_t again for now.

Jakub Czapiga ad6157ebdf timestamps: Rename timestamps to make names more consistent
This patch aims to make timestamps more consistent in naming,
to follow one pattern. Until now there were many naming patterns:
- TS_START_*/TS_END_*
- TS_BEFORE_*/TS_AFTER_*
- TS_*_START/TS_*_END
This change also aims to indicate, that these timestamps can be used
to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.

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.

Subrata Banik 6de8b42482 arch/x86: Refactor the SMBIOS type 17 write function
List of changes:
1. Create Module Type macros as per Memory Type
(i.e. DDR2/DDR3/DDR4/DDR5/LPDDR4/LPDDR5) and fix compilation
issue due to renaming of existing macros due to scoping the Memory
Type.
2. Use dedicated Memory Type and Module type for `Form Factor`
and `TypeDetail` conversion using `get_spd_info()` function.
3. Create a new API (convert_form_factor_to_module_type()) for
`Form Factor` to 'Module type' conversion as per `Memory Type`.
4. Add new argument as `Memory Type` to
smbios_form_factor_to_spd_mod_type() so that it can internally
call convert_form_factor_to_module_type() for `Module Type`
conversion.
5. Update `test_smbios_form_factor_to_spd_mod_type()` to
accommodate different memory types.
6. Skip fixed module type to form factor conversion using DDR2 SPD4
specification (inside dimm_info_fill()).

Refer to datasheet SPD4.1.2.M-1 for LPDDRx and SPD4.1.2.L-3 for DDRx.

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:

Jakub Czapiga 29faa8a5a2 tests/stubs/console: Allow enabling printk to print to stdout
By adding TEST_PRINT=1 to <test-name>-config field or by passing it as
a parameter to make one can enable printing in printk() and vprintk().
This can be helpful when developing unit tests.
Note, that to effectively enable or disable printk() printing to stdout,
test(s) have to be recompiled.

Jakub Czapiga 7c6081e02b tests: Improve test output readability
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)

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.

Yu-Ping Wu 941db0e55c helpers: Add GENMASK macro
The GENMASK is defined in multiple files (with various names such as
MASKBIT), which sets certain consecutive bits to 1 and leaves the others
to 0. To avoid duplicate macros, add GENMASK macro to helpers.h.

GENMASK(high, low) sets bits from `high` to `low` (inclusive) to 1. For
example, GENMASK(39, 21) gives us the 64-bit vector 0x000000ffffe00000.

Remove duplicate macro definitions. Also utilize GENMASK for _BF_MASK in
mmio.h.

Patrick Georgi 53ea1d44f0 util/kconfig: Uprev to Linux 5.13's kconfig

because the intermediate states weren't able to build coreboot:

 - one to remove everything that wasn't our own code, leaving only
   regex.[ch], toada.c, description.md and Makefile.inc.
 - 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.
