6b5bc77c9b treewide: Remove "this file is part of" lines
Stefan thinks they don't add value.

Command used:

The exceptions are for:

f3f36faf35 src (minus soc and mainboard): Remove copyright notices
They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
  copyright holder?
- People sometimes have their editor auto-add themselves to files even
  though they only deleted stuff
- Or they let the editor automatically update the copyright year,
  because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?

Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

e0060a80f0 ec/google/chromeec: Fix dev ops for chromeec
CB:38541 ("ec/google/chromeec: Add SSDT generator for ChromeOS EC")
added a new device_operations structure for chromeec for handling ACPI
SSDT generation. However, this resulted in the original
device_operations which handled lpc read resources to be skipped. This
change fixes the above regression by combining the device operations
for reading resources and ACPI SSDT generation into a single structure
and retains the old logic for enabling of pnp devices.

9ed10bff31 ec/google/chromeec: Introduce SKU_ID helpers
The following introduces helpers that, by default,
accommodate a larger SKU id space. The following
is the rational for that:

 Allow INT32_MAX SKU id encodings beyond UINT8_MAX.
 This allows for the SKU id to accommodate up to 4 bytes
 however we reserve the highest bit for SKU_UNKNOWN to be encoded.

However, the legacy UINT8_MAX encoding is supported by leveraging
the Kconfig by overriding it with the legacy max of 0xff.

Follow ups migrate boards to this common framework.

V.2: Fixup array size && drop sku_id SKU_UNKNOWN check and pass
     whatever is set to userspace as firmware doesn't care about
     the value.
V.3: Use SPDX-License header.

eb3cd85610 ec/google/chromeec: Add SSDT generator for ChromeOS EC
Upcoming patches for the Linux kernel (5.6 ?) would like to consume
information about the USB PD ports that are attached to the device. This
information is obtained from the CrOS EC and exposed in the SSDT ACPI
table.

Also, the device enable for this PCI device is moved from ec_lpc.c to
a new file, ec_chip.c, where EC-related ACPI methods can live.  It
still allows other code to call functions on device enable (so that
PnP enable for the LPC device still gets called).

After ChromiumOS CL:1293132 and CL:1295890, Chrome EC can store the flag
telling if the last reboot was triggered by AP watchdog for some boards
(e.g., Kukui).

This CL adds a new function google_chromeec_get_ap_watchdog_flag(),
which reads the AP watchdog flag from Chrome EC, and updates the tables
of reset causes and reset flags.

A new Kconfig option CHROMEOS_USE_EC_WATCHDOG_FLAG is added for
elog_handle_watchdog_tombstone() to determine if watchdog reset was
triggered by the AP watchdog flag from EC instead of the tombstone in
AP.

This patch clarifies the definition of google_chromeec_command.

Currently absence of the definition isn't causing any problem because
wrapper APIs check 'ret != 0' or wrapper APIs check 'ret < 0' for an
interface which returns only negative error codes.

However, there is a chance that a new wrapper API will be addedl which
check 'ret < 0' to catch errors, assuming other interfaces behave the same.
Or existing wrapper APIs will be broken as soon as they're compiled for
another interface.

d182b63347 mainboard/google/fizz: Check HDMI HPD and DisplayPort HPD
Some type-c monitors do not immediately assert HPD. If we continue
to boot without HPD asserted, Depthcharge fails to show pictures
on a monitor even if HPD is asserted later.

Also, if an HDMI monitor is connected, no wait is needed. If only
an HDMI monitor is connected, currently the API always loops until
the stopwatch expires.

This patch will make the AP skip DisplayPort wait loop if it detects
an HDMI monitor. And if an HDMI monitor is not detected, the AP will
wait for DisplayPort mode (like before) but also its HPD signal.

This patch also extends the wait loop time-out to 3 seconds.

BUG=b:72387533
BRANCH=none
TEST=Verify firmware screen is displayed even when a type-c monitor
does not immediately assert HPD. Verify if HDMI monitor is connected,
AP does not wait (and firmware screen is displayed on HDMI monitor).

1dfc2c3e54 google/chromeec: Enable unified host event programming interface
Unified Host Event Programming Interface (UHEPI) enables a unified host
command EC_CMD_PROGRAM_HOST_EVENT to set/get/clear different host events.
Old host event commands (0x87, 0x88, 0x89, 0x8A, 0x8B, 0x8C, 0x8D, 0x8E,
0x8F) is supported for backward compatibility. But newer version of
BIOS/OS is expected to use UHEPI command (EC_CMD_PROGRAM_HOST_EVENT)

The UHEPI also enables the active and lazy wake masks. Active wake mask
is the mask that is programmed in the LPC driver (i.e. the mask that is
actively used by LPC driver for waking the host during suspended state).
It is same as the current wake mask that is set by the smihandler on host
just before entering sleep state S3/S5. On the other hand, lazy wake masks
are per-sleep masks (S0ix, S3, S5) so that they can be used by EC to set
the active wake mask depending upon the type of sleep that the host has
entered. This allows the host BIOS to perform one-time programming of
the wake masks for each supported sleep type and then EC can take care
of appropriately setting the active mask when host enters a particular
sleep state.

BRANCH=none

ChromeEC is getting ready to bump up the hostevents and wake masks to
64-bits. The current commands to program hostevents/wake masks will
still operate on 32-bits only. A new EC host command will be added to
handle 64-bit hostevents/wake masks. In order to prevent individual
callers in coreboot from worrying about 32-bit/64-bit, the same API
provided by google/chromeec will be updated to accept 64-bit
parameters and return 64-bit values. Internally, host command handlers
will take care of masking these parameters/return values to
appropriate 32-bit/64-bit values.

47dffa59f3 chromeec: Remove checks for EC in RO
This patch removes checks that ensure EC to be in RO for recovery
boot. We do not need these checks because when recovery is requested
automatically (as opposed to manually), we show 'broken' screen where
users can only reboot the device or request recovery manually.

If recovery is requested, Depthcharge will check whether EC is in RO
or not and recovery switch was pressed or not. If it's a legitimate
manual recovery, EC should be in RO. Thus, we can trust the recovery
button state it reports.

This patch removes all calls to google_chromeec_check_ec_image,
which is called to avoid duplicate memory training when recovery
is requested but EC is in RW.

Chrome EC uses IO ports 0x800 -> 0x9ff to communicate over LPC;
however, those ports were not declared as a resource. This had two
major downsides:
* It allowed the allocator to assign said ports to other devices
* It required manually open up an IO window in the LPC bridge.
The LPC bridge on many chromeec boards had to be painstakingly
adjusted to meet these constraints.

The advantage of declaring the resources upfront is that the lpc
bridge can now scan its child resources and automatically open up
IO windows, as requested by its LPC children devices.
