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.

Copy ec_commands.h directly from ChromiumOS EC repository (CL:1520574).
Since ec_commands.h already defines usb_charge_mode and only
USB_CHARGE_MODE_DISABLED is used in coreboot, enum usb_charge_mode is
removed from ec.h.
To avoid redefinition of the BIT macro, #ifndef check is added to
include/types.h.

google_chromec_get_event() depends on the main copy of EC which is
used by ACPI subsytem in the kernel for querying events.
google_chromeec_get_event() also clears the event from EC. Thus if the
kernel has to identify the wake source, it has no way to do that. Thus
instead depend on events_copy_b to log the wake source. Please look at
go/hostevent-refactor for more info.

For files built in ramstage and smm -classes, testing

All chip_operations are exluded with use of DEVTREE_EARLY

The BBST() method writes an updated status flag mask that is intended
to be stored back in the battery object. This value needs to be
passed as a reference to an object to prevent it from being evaluated
at the time the method is loaded or it will not actually update the
BSTP value in the battery device.
This was tested by instrumenting the _BST method in the primary
battery and ensuring the value can be updated by the BBST method.

indicates that the EC should transition to S0ix mode and this is
preventing the kernel from going into S0ix on the first try.
As a workaround if we read back from the EC RAM while still in the

This change adds support for the UCSI specification in order to
provide information about the Type-C port and an interface to
perform power and data role swap.
This change is split across the DSDT and SSDT, with the shared
memory and operation region declared in the SSDT after being
allocated in CBMEM.
The OS will fill in the registers in the system memory region and
then call the _DSM method wtih a read or write argument. The DSM
method will copy the required registers to/from the system memory
and the EC and perform the write or read action.
Responses from the EC will generate a new SCI with event code 0x79
which will notify this UCSI ACPI device and the OS driver will take
action to read status from the EC.

There are two known reverse-engineered ways to manage battery
thresholds.
This patch implements them and adds a way to enable them for
different mainboards.
Tested on W530 with 4.18.3-gentoo kernel and X220 with 4.20.11.
Works fine with new Linux userspace API for controlling battery
thresholds, available since 4.17.
(/sys/class/power_supply/BAT0/charge_(start|stop)_threshold).
The new API is supported by TLP (you might need to set NATACPI_ENABLE=1
in /etc/tlp.conf).
tpacpi-bat works fine too.

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.

Add an ACPI device that is compatible with the Intel Virtual
Button kernel driver for reporting tablet mode state and various
virtual button events that may come from the EC.
This driver is used in Windows and in the Linux kernel at
drivers/platform/x86/intel-vbtn.c
Because of a check in the kernel driver it expects the board to
define the SMBIOS enclosure type as convertible for the check at
driver load time for tablet/laptop and dock/undock to work.
The virtual tablet mode button will proxy the tablet mode state
sent from the Sensor Hub to a SW_TABLET_MODE event in the kernel.
The virtual power button is used during S0ix for the EC to wake
the system with an SCI. There are separate press and release
events which are sent for completeness, although the kernel driver
will ignore the release event.

parameter by not dereferencing. This led to the returned csum

Fix this by storing the returned checksum in a temp variable,
and only assigning to csum when the pointer isn't NULL;

EC_SYNC_IRQ from EC to host is level-triggered in practice and
configuring it as edge-triggered on the host results in host missing
events if there are multiple events queued on the EC side. This is
because Linux kernel driver reads one event per irq and the EC does
not de-assert the interrupt line until all events are drained
out. This results in event queue being filled up completely on the EC
and the host failing to see any of those events.
This change configures EC_SYNC_IRQ as level triggered to allow the
host to read events from the the EC as long as the line is asserted.

If remaining charge is more than x% of the full capacity, the
remaining charge is raised to the full capacity before it's
reported to the rest of the system.
Some batteries don't update full capacity timely or don't update it
at all. On such systems, compensation is required to guarantee
the remaining charge will be equal to the full capacity eventually.
On some systems, Rohm charger generates audio noise when the battery
is fully charged and AC is plugged. A workaround is to do charge-
discharge cycles between 93 and 100%. On such systems, compensation
was also applied to mask this cycle from users.
This used to be done in ACPI, thus, all software components except EC
was able to see the compensated charge. This patch is part of the
effort of moving the logic to EC. With this and the EC changes, EC
can see what the rest of the system sees, thus, can control LEDs
synchronously (to the display percentage).
Another rationale of this move is EC can perform more granular and
precise compensation than ACPI since it has more knowledge about the
battery and the charger.

Add the base ACPI support for the Wilco embedded controller, using
ASL 2.0 syntax throughout.
This includes the EC device and its resources, as well as the layout
for the EC RAM and the functions needed to read and write to the EC RAM.
The EC RAM address space is typically read/write, and so the ACPI EC
device expects that a defined Field can be read and/or written. With
this EC the read and write address spaces are different. For example,
a read from address zero will return data that is unrelated to what a
write to address zero expects.
This makes using a typical OperationRegion to describe the EC RAM
address space somewhat impracticle, since field definitions would
overlap. Instead, methods are provided for reading and writing to an
EC RAM offset, and the EC RAM layout is defined as a Package that
describes offset+mask for read or write fields within the EC RAM.

Add a function for use in bootblock stage that performs early init
of the EC, in particular setting it up for UART passthrough so a
legacy serial port can be used by the host.
This needs to be called by the mainboard that intends to use it
in bootblock in order for the UART to be available in later stages.
Some of the PNP style programming may look odd, but it is following
the EC specification which is not entirely standard. This code has
been tested on a board with this EC and it is functional.

Add EC handlers for specific SMM actions:
- on entry to sleep state tell the EC to save state and to prepare for
the host to enter sleep
- on ACPI enable/disable send command to the EC
- add a function to print SMI reasons when eSPI SMI is received
These need to be called by the mainboard handlers which will be done
when a board is added that uses this EC.

Add a chip_operations structure for Wilco EC and hook it into the device
tree so it can be initialized at boot.
Reserve the device resources specified in Kconfig, which will also
create the device IO windows if they have not been created in bootblock.
If the IO windows already exist (becauase they were specified in the
mainboard devicetree.cb) then this will find the existing entry instead.
During device init stage prepare the keyboard for use, which is required
for it to be functional in firmware and OS with this EC. Also send a
command to the EC telling it to pass the power button through to the
host for processing.

The Google "Wilco" Embedded Controller is a new embedded controller that
will be used in some future devices. The mailbox interface is simliar
to the existing Chromium EC protocol version 3, but not close enough
that it was convenient to re-use the full Chrome EC driver.
This commit adds the basic mailbox interface for ramstage which will be
used by future commits to send varous mailbox commands during the boot
process. The IO base addresses for the mailbox interface are defined in
Kconfig so they can be changed by the mainboard if needed.

Some boards are adding a second pin used for synchronization between
the EC and AP. This is a direct connection between the EC and the SOC
that is intended to provide a lower latency interrupt signal for
sensors on the EC.
Currently the runtime EC interrupts assert an SCI before eventually
resulting in a Notify() on the MKBP device that the sensor driver users.
These extra layers add processing time and require additional EC
communication to determine the event source.
This interface was tested on a reworked Nocturne board with modified
EC and a modified kernel driver to ensure that the interrupt asserts
as expected and can be used by the kernel driver.
