The new util/chromeos/update_ec_headers.sh utility is used to update

ec_cmd_api.h is a new file from the chrome EC repo which defines the API
for communicating with the EC. It is a companion to the existing
ec_commands.h by defining functions corresponding to EC host command
opcodes and request/response struct definitions.

This reverts commit 4dba71fd25.
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

With CB:16732, EC can provide default lid switch implementation(LID0
ACPI device). Up until that point, mainboard has been providing default
switch implementation. When EC provides lid switch implementation, the
lid switch state is read from EC either through MMAP or LPC interface.
Hence there is no need to keep mainboard's LIDS ACPI object in sync with
EC's lid switch state. Use only EC's lid switch state on boards using
EC's implementation. This paves the way to remove LIDS ACPI object on
those mainboards.

Handle the new host event EC_HOST_EVENT_BODY_DETECT_CHANGE.
Previously, the EC sent the host event EC_HOST_EVENT_MODE_CHANGE when
body detection changed between lap/desk mode. However, that event is a
wake event, which resulted in spurious AP wake events being triggered
when the EC detected lap/desk mode changes while the AP was suspended.
To resolve this, the new host event EC_HOST_EVENT_BODY_DETECT_CHANGE was
added, which will not be a wake event. This CL adds handling for the new

command's return value as stored in cmd_code because that level of
detail is not very interesting. Higher value error codes are returned in
actual result structures.
This host command can return EC_RES_ERROR for out of range PWM values
which is already a generic error and unlikely to happen since we already
limit the range to 0..100 here. Finally, none of the callers in coreboot

PNOT() should be called when the battery status changes, to give the SOC
an opportunity to handle it. This is in preparation for the low/no
battery boot changes.
This CL also updates the PNOT() comments to better match the name of the
function and why it's called.

The agah EC code will monitor adapter current to choose corresponding
DPTF oem variable table. When it changes, this event will send to the
ACPI FW through host event and then pass onto the DPTF kernel driver.
This patch adds support for that feature.

TEST=add Printf() calls to the ACPI,
and check these Printf() will show up in the kernel log

The DPTF power participant device needs to be notified when power
source changes so it can re-evaluate power source and power source
change count, this can be later used by DPTF along with methods
provided by EC.

The flag EC_BATT_FLAG_CUT_OFF was added with the CL:
3704470: battery: Set battery cutoff flag
https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/3704470
This flag is set in the ACPI memory mapped area when the command
`ectool batterycutoff` is issued so ACPI code can respond
appriopriately. This CL adds the flags to coreboot ACPI.

Since there are many identifiers whose name contain "__unused" in
headers of musl libc, introducing a macro which expands "__unused" to
the source of a util may have disastrous effect during its compiling
under a musl-based platform.
However, it is hard to detect musl at build time as musl is notorious
for having explicitly been refusing to add a macro like "__MUSL__" to
announce its own presence.
Using __always_unused and __maybe_unused for everything may be a good
idea. This is how it works in the Linux kernel, so that would at least
make us match some other standard rather than doing our own thing
(especially since the other compiler.h shorthand macros are also
inspired by Linux).
