Crashlog has error records and PMC reset records two parts. When we
send ipc cmd "PMC_IPC_CMD_ID_CRASHLOG_ON_RESET", PMC reset record is
enabled. At each warm/cold/global reset, crashlog would be triggered.
The cause of this crash would be "TRIGGER_ON_ALL_RESETS", it is used to
catch unknown reset reason. At the same time, we would see [Hardware
Error] in the kernel log.
If we default enable TRIGGER_ON_ALL_RESETS, we would have too many false
alarm. Now we disable PMC reset records part by default. And we could
enable it when we need it for the debug purpose.
The generated bert dump is under /var/spool/crash/, we could check this
path to verify this CONFIG disable/enable status.
BUG=b:202737385
TEST=No new bert dump after a warm reset.

Technically, it's not depending on the hardware but on the software
(OS/payload), if the PM Timer is optional. OSes with ACPI >= 5.0A
support disabling of the PM Timer, when the respective FADT flag is
unset. Thus, drop this guard.
For platforms without hardware PM Timer (Apollo Lake, Gemini Lake) the
Kconfig `USE_PM_ACPI_TIMER` depends on `!NO_PM_ACPI_TIMER`.
As of this change, new platforms must either implement code for
disabling the hardware PM timer or select `NO_PM_ACPI_TIMER` if no such

With using a Kconfig option to add the x86 LAPIC support code to the

in the CPU/SoC Makefile. Comparing which CPU/SoC Makefiles added
(cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding
MTRR code selection patch and having verified that all platforms
added the MTRR code on that patch shows that soc/example/min86 and
soc/intel/quark are the only platforms that don't end up selecting the
LAPIC code. So for now the default value of CPU_X86_LAPIC is chosen as y
which gets overridden to n in the Kconfig of the two SoCs mentioned

All x86-based CPUs and SoCs in the coreboot tree end up including the
Makefile in cpu/x86/mtrr, so include this directly in the Makefile in
cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new
x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is
selected be default could be added and the new CPU/SoC without MTRR
support can override this option that then will be used in the Makefile
to guard adding the Makefile from the cpu/x86/mtrr sub-directory.
In cpu/intel all models except model 2065X and 206AX are selcted by a
socket and rely on the socket's Makefile.inc to add x86/mtrr to the
subdirs, so those models don't add x86/mtrr themselves. The Intel
Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the
subdirs. The Intel Xeon SP SoC directory contains two sub-folders for
different versions or generations which both add x86/mtrr to the subdirs
in their Makefiles.

error if it didn't return CB_SUCCESS and passes the return value of

Normally for vboot-enabled x86 board, the VBNV region is stored in CMOS
and backed up to flash (RW_NVRAM). However, on the very first boot after
a flash of the full SPI image (so RW_NVRAM is empty), if
RTC_BATTERY_DEAD is set, coreboot persistently requests recovery before
FSP-M finishes (which appears to be the current location that
RTC_BATTERY_DEAD is cleared on this platform). This is because
vbnv_cmos_failed() will still return 1. Therefore, immediately after
reading RTC_BATTERY_DEAD, it is cleared. This prevents an infinite boot
loop when trying to set the recovery mode bit.
Note that this was the behavior for previous generations of Intel PMC
programming as well (see southbridge/intel, soc/skylake, soc/broadwell,
etc).

FspMultiPhaseSiInit API was introduced with FSP 2.2 specification
onwards. EnableMultiPhaseSiliconInit is an arch UPD also introduced
as part of FSP 2.2 specification to allow calling FspMultiPhaseSiInit
API.
However, some platforms adhere to the FSP specification but
don't have arch UPD structure, for example : JSL, TGL and Xeon-SP.
Out of these platforms, TGL supports calling of FspMultiPhaseSiInit
API and considered EnableMultiPhaseSiliconInit as a platform-specific
UPD rather than an arch UPD to allow calling into FspMultiPhaseSiInit
API.
It is important to ensure that the UPD setting and the callback for
MultiPhaseInit are kept in sync, else it could result in broken
behavior e.g. a hang is seen in FSP if EnableMultiPhaseSiliconInit
UPD is set to 1 but the FspMultiPhaseSiInit API call is skipped.
This patch provides an option for users to choose to bypass calling
into MultiPhaseSiInit API and ensures the EnableMultiPhaseSiliconInit
UPD is set to its default state as `disable` so that FSP-S don't
consider MultiPhaseSiInit API is a mandatory entry point prior to
calling other FSP API entry points.
List of changes:
1. Add `FSPS_HAS_ARCH_UPD` Kconfig for SoC to select if
`FSPS_ARCH_UPD` structure is part of `FSPS_UPD` structure.
2. Drop `soc_fsp_multi_phase_init_is_enable()` from JSL and Xeon-SP
SoCs, a SoC override to callout that SoC doesn't support calling
MultiPhase Si Init is no longer required.
3. Add `FSPS_USE_MULTI_PHASE_INIT` Kconfig for SoC to specify if
SoC users want to enable `EnableMultiPhaseSiliconInit` arch UPD (using
`fsp_fill_common_arch_params()`) and execute FspMultiPhaseSiInit() API.
4. Presently selects `FSPS_USE_MULTI_PHASE_INIT` from IA TCSS common
code.
5. Add `fsp_is_multi_phase_init_enabled()` that check applicability of
MultiPhase Si Init prior calling FspMultiPhaseSiInit() API to
honor SoC users' decision.
6. Drop `arch_silicon_init_params()` from SoC as FSP driver (FSP 2.2)
would check the applicability of MultiPhase Si Init prior calling
FspMultiPhaseSiInit() API.
Additionally, selects FSPS_HAS_ARCH_UPD for Alder Lake as Alder Lake
FSPS_UPD structure has `FSPS_ARCH_UPD` structure and drops
`arch_silicon_init_params()` from SoC
`platform_fsp_silicon_init_params_cb()`.
Skip EnableMultiPhaseSiliconInit hardcoding for Tiger Lake and uses
the fsp_is_multi_phase_init_enabled() function to override
EnableMultiPhaseSiliconInit UPD prior calling MultiPhaseSiInit FSP API.
TEST=EnableMultiPhaseSiliconInit UPD is getting set or reset based on
SoC user selects FSPS_USE_MULTI_PHASE_INIT Kconfig.

Intel TGL BIOS specification (doc ##611569) Revision 0.7.6 Section
7.2.5.1.5 recommends reserving the following resources for each PCIe
USB4 root port:
- 42 buses
- 194 MiB Non-prefetchable memory
- 448 MiB Prefetchable memory
This change enables reserving of resources for USB4 when mainboard
selects the newly added Kconfig SOC_INTEL_ENABLE_USB4_PCIE_RESOURCES.
This is similar to the change for ADL in commit 8d11cdc6fa
("soc/intel/alderlake: Add Kconfig for recommended PCIe TBT resources").

The code under `cpu/x86/tsc` is only compiled in when its `Makefile.inc`

option is enabled.
Include `cpu/x86/tsc/Makefile.inc` once from `cpu/x86/Makefile.inc` and
drop the now-redundant inclusions from platform code. Also, deduplicate
the `UDELAY_TSC` guards.
