After final production, it's possible by setting particular
bit using DCFG the OEM/ODM locks down thermal tuning beyond
what is usually done on the given platform.
In that case user space calibration tools should not try
to adjust the thermal configuration of the system.
By adding new DCFG (Device Configuration) it allows the
OEM/ODM to control this thermal tuning mechanism. They can
configure it by adding dcfg config under overridetree.cb file.
The default value for all bits is 0 to ensure default behavior
and backwards compatibility.
For an example if Bit 0 being set represents Generic DTT UI
access control is disabled and Bit 2 being set represents DTT
shell access control is disabled.
Each bit represents different configuration access control
for DTT as per BIOS specification document #640237.
It also gives the provision for user space to check the current
mode. This mode value is based on BIOS specification document
number #640237.
BUG=b:272382080
TEST=Build, boot on rex board and dump SSDT to check DCFG value.
Also, verified the newly added sysfs attribute "production_mode"
present under /sys/bus/platform/devices/INTC1042:00 path.

Macros can be confusing on their own; hiding commas make things worse.
This can sometimes be downright misleading. A "good" example would be
the code in soc/intel/xeon_sp/spr/chip.c:
CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev,
This appears as CHIP_NAME() being some struct when in fact these are
defining 2 separate members of the same struct.
It was decided to remove this macro altogether, as it does not do
anything special and incurs a maintenance burden.

The .inc suffix is confusing to various tools as it's not specific to
Makefiles. This means that editors don't recognize the files, and don't
open them with highlighting and any other specific editor functionality.
This issue is also seen in the release notes generation script where
Makefiles get renamed before running cloc.

To help identify the licenses of the various files contained in the
coreboot source, we've added SPDX headers to the top of all of the
.c and .h files. This extends that practice to Makefiles.
Any file in the coreboot project without a specific license is bound
to the license of the overall coreboot project, GPL Version 2.
This patch adds the GPL V2 license identifier to the top of all
makefiles in the drivers directory that don't already have an SPDX
license line at the top.

This reverts commit 4dba71fd25c91a9e610287c61238a8fe24452e4e.
Add multiple fan support for dptf policies.
This also fixes the Google Meet resolution drop issue as per
b:246535768 comment#12. When system starts Google Meet video call,
it uses the hardware accelerated encoder as expected. But, as soon as
another system connects to the call, an immediate fallback is observed
from hardware to software encoder. Due to this, Google Meet resolution
dropped from 720p to 180p. This issue is observed on Alder Lake-N SoC
based fanless platforms. This same issue was not seen on fan based
systems. With the fix in dptf driver where fan configures appropriate
setting for only fan participant, not for other device participants,
able to see consistent 720p resolution.
BUG=b:246535768,b:235254828
BRANCH=None
TEST=Built and tested on Alder Lake-P Redrix system for two fans

otherwise, it will use the "new" style, which are regular
8-character _HIDs.

In the initial DPTF refactor, the scope of the TCPU device was
incorrectly set as \_SB, instead of \_SB.PCI0. However, because of the
way that the acpi_inject_dsdt() callback currently works (it injects
contents before the dsdt.aml file), the Scope where the TCPU
device lives (\_SB.PCI0) doesn't exist yet. Therefore, to avoid playing
games with *when* things are defined in the DSDT, switch to defining all
of the DPTF devices in the SSDT.

\_SB.DPTF.IDSP adverties to the DPTF daemon which policies the
implementation supports. Added a new acpigen function to figure out
which policies are used, and fills out IDSP appropriately.

DPTF has several options on how to control the fan (fine-grained speed
control, minimum speed change in percentage points, and whether or not
the DPTF device should notify the Fan if it detects low speed).
Individual TSRs can also set GTSH, which is the amount of hysteresis
inherent in the measurement, either from circuitry (if analog), or in
firmware (if digital).

This change adds support for emitting the PPCC table, which describes
the ranges available as knobs for DPTF to tune. It can support min/max
power, min/max time window for averaging, and the minimum adjustment size
(granularity or step size) of each power limit. The current implementation
only supports PL1 and PL2.

This change adds support for generating the _FPS table for the DPTF Fan
object. The table describes different levels of fan activity that may be
applied to the system in order to actively cool it. The information
includes fan speed at a (rough) percentage level, fan speed in RPM,
potential noise level in centibels, and power in mA.

This change generates the DPTF TCHG.PPSS table in the SSDT. This table
describes different charging rates which are available to use. DPTF
can pick different rates in order to passively cool (or not) the
system.

This patch adds support for DPTF Critical Policies, which are consist
of Method definitions only. They are `_CRT` and `_HOT`, which are
defined as temperature thresholds that, when exceeded, will execute a
graceful suspend or a graceful shutdown, respectively.

In this DPTF implementation, the participant device objects are written
into the DSDT with only minimal Names attached (_HID/_ADR, _STA, _UID,
PTYP, and _STR). All other Methods & Names will be written into the
SSDT. If a device is not used in any policy, then its _STA is set to
return 0 ("off").

Currently, configuring and reviewing DPTF parameters is difficult
because DPTF tables and methods are defined in static ASL files, and are
littered with #ifdefs which both define parameters and influence
behavior (e.g., whether a method is included or not). This patch train
is an effort to bring DPTF support to our ACPI DSDT/SSDT generation
framework.
This first patch is very minimal, and includes only creation of the
DPTF device (in the DSDT).
