b03d6f15b4 soc/intel/meteorlake: Fix incorrect prev_sleep_state issue
The patch fixes indication of incorrect `prev_sleep_state` on the next
boot after global reset trigger. The existing code misses an important check about `if PCH doesn't set the WAK_STS` while checking power
failure. As a result, every early warm/global reset is considered
as power failure after looking into the PMC MMIO CON-A register
alone (as ignoring the ACPI PM_CTRL.WAK_STS bit).

As per the code comment this code logic is expected to check the power
failure reason if PCH doesn't set the WAK_STS while waking from G3
state.

TEST=Able to build and boot google/rex.

Without this patch:

Observation: Resuming after a warm reset is considered as
`prev_sleep_state 5` although the SLP_TYP is zero and WAK_STS bit
is set.

d4cc902c57 soc/intel/meteorlake: Avoid redundant chipset programming in romstage
This patch refactors the mainboard_romstage_entry() function to avoid
redundant chipset programming caused by global reset due to CSE FW
sync operation. Hence, keeping only the minimal and mandatory
operations required to perform CSE FW sync successfully.

This would help to optimize the boot flow by removing redundant
programming like SA, SMBUS twice in every CSE FW update path.

ba2cef5b54 soc/intel/common/block/early_graphics: Introduce a 200 ms delay
It has been reported that the PEIM graphics driver may temporarily
fail communication with the display if the time between libgfxinit
turning off the displays and the PEIM driver initialization is too
short. 200 ms has been identified as a safe delay.

This is a temporary workaround and an investigation is in progress to
come up with a better and long term solution.

adbdc5c1bd soc/intel/elkhartlake: Provide a way to enable real-time tuning
Intel provides a Real-Time Tuning Guide for Elkhart Lake to improve
real-time behaviour of the SoC (see Intel doc #640979). It describes,
amongst knobs for the OS, a couple of firmware settings that need to be
set properly to reduce latencies in all the subsystems. Things like
clock and power gating as well as low power states for peripherals and
buses are disabled in this scenario.

This patch takes the mentioned UEFI parameters from the guide and
translates them to FSP-M and FSP-S parameters. In addition, a chip
config switch guards this tuning which can be selected on mainboard
level if needed.

When this real-time tuning is enabled, the overall system performance
in a real-time environment can be increased by 2-3%.

The idea here is to decouple ME specification defined structures from
the source file `.c` and keep those into header files so that in future
those spec defined header can move into common code.

The current and future SoC platform will be able to select the correct
ME spec header based on the applicable config. It might be also

f3a672908f device/Kconfig: Fix selection of software connection manager
The patch that introduced the selection of software connection manager,
CB:64561 - 060df17f1d (soc/intel/alderlake/acpi: Add Kconfig options for
SCM and FCM) added a default to enable the software configuration
manager directly in the choice.

This leads to warnings when running make menuconfig:
src/soc/intel/alderlake/Kconfig:439:
warning: defaults for choice values not supported
src/soc/intel/meteorlake/Kconfig:337:
warning: defaults for choice values not supported
src/soc/intel/tigerlake/Kconfig:299:
warning: defaults for choice values not supported

I'm not sure why the Kconfig linter didn't catch this, but this
issue is currently breaking the build for me.  This patch fixes
it so that instead of setting the default directly, a new Kconfig
value is selected that then sets the default correctly.

205437b759 soc/intel/common: Fix cpu index calculation
get_cpu_index() helper function returns cpu's index based on it's APIC
id position from the ascending order list of cpus' APIC IDs.
In order to calculate the cpu's index, the helper function needs to
traverse through each cpu node to find their APIC IDs. So, the function
traverse the CPU node list from the cpu whose APIC ID is 0 assuming it
is the first cpu node in the list. This logic works fine where BSP's
APIC ID is 0. But, starting from MTL, APIC ID for BSP need not be 0 as
APIC ID numbering first get assigned for CPU Die Efficient cores, then
Performance cores.
Please refer section# 6.1 of doc#643504 for more details on APIC IDs.

Considering the APIC Id allotment for MTL cores, as existing code
traversing begins from the cpu that has APIC Id#0 which may not be the
first cpu node in the list so index calculation results in wrong value.

The patch addresses above described issue by traversing all the CPU
nodes to calculate the cpu index. Also, prevents inconsistent report
of /sys/devices/system/cpu/cpu*/cpufreq/* and
/sys/devices/system/cpu/cpuXX/acpi_cppc  on each reboot.

TEST=Verified that the get_cpu_index helper function returns the correct
index id for a CPU on Rex.

and cbmem_top that the allocator will consider as unassigned memory.
Resources could incorrectly be assigned to that region and the final
MTRR solution will also try to skip that hole, therefore using a lot
more variable MTRRs than needed.

TESTED on Archer City 2S system: Uses 1 variable MTRR in the final
setup instead of 7.

060df17f1d soc/intel/alderlake/acpi: Add Kconfig options for SCM and FCM
Software Connection Manager doesn't work with Linux 5.13 or later,
resulting in TBT ports timing out. Not advertising this results
in Firmware Connection Manager being used and TBT works
correctly.

Add Kconfig options to chose between SCM (Software Connection
Manager) and FCM (Firmware Connection Manager). FCM is primary, as
it's more compatible save for ChromeOS devices as ChromeOS uses
SCM.

Linux patch:

Tested with StarBook Mk VI (i7-1260P).
