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%.

This patch moves ME host firmware status register structures to ME
header file. It also marks unused structure fields to reserved.
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
beneficial if two different SoC platforms would like to use the same
ME specification and not necessarilly share the same SoC directory.

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

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.

IFDv1 always has 8 regions, while IFDv2 always has 16 regions.
It's platform specific which regions are used or are reserved.
The 'SPI programming guide' as the name says is a guide only,
not a specification what the hardware actually does.
The best to do is not to rely on the guide, but detect how many
regions are present in the IFD and expose them all.
Very early IFDv2 chipsets, sometimes unofficially referred to as
IFDv1.5 platforms, only have 8 regions. To not corrupt the IFD when

When AP boots up after Cr50 firmware update and reboot, AP finds
that Cr50 reset is required for Cr50 to pick the new firmware so
it trigger Cr50 reset and power off the system, AP expects system

the case for Chromebox, Chromebox EC set AP_IDLE flag when system
is shutting down, when AP_IDLE flag is set in EC, the system stays
at S5/G3 and wait for power button presssend. It cause an issue in
factory that the operator needs to press power button to power on
the DUT after Cr50 firmware update.

Due to mainboard restrictions a SATA link at Gen 3 (6 Gbps) can cause
issues as the margin is not big enough. Limit SATA speed to Gen 2 to
achieve a more robust SATA connection.

In cases where there are limitations on the mainboard it can be
necessary to limit the used SATA speed even though both, the SATA
controller and disk drive support a higher speed rate. The FSP parameter
'SataSpeedLimit' allows to set the speed limit.
This patch provides a chip config so that this FSP parameter can be
set as needed in the devicetree on mainboard level.

Now that power sequencing has been implemented, switch from using ACPI
"probed" flag to "detect" flag for all i2c touchscreens. This removes
non-present devices from the SSDT and relieves the OS of the burden of
probing.
BUG=b:121309055
TEST=build/boot Windows/linux on multiple dedede variants, verify all
touchscreens functional in OS, dump ACPI and verify only i2c devices
actually present on the board have entries in the SSDT.

The GPIOs themselves are configured as level triggered, and the drivers
(both Linux and Windows) work better with LEVEL vs EDGE triggering.

For touchscreens on dedede variants, drive the enable GPIO high
starting in romstage, then disable the reset GPIO in ramstage. This will
allow coreboot to detect the presence of i2c touchscreens during ACPI
SSDT generation (implemented in a subsequent commit).
Since the fast majority of dedede variants have a touchscreen option,
and those that do use the same GPIOs for enable/reset, set the GPIOs for
touchscreen operation in the baseboard and then override for the few (3)
variants that do not have a touchscreen.

Add method variant_romstage_gpio_table() with empty weak implementation
to allow variants to override as needed for touchscreen power
sequencing (to be implemented in a subsequent commit). Call method
