db48f7ea48 ec/google/wilco: Add wake pin configuration
Add a way for the mainboard to provide a wake pin that the EC
will use to wake the system.  This defines a _PRW object.

f5d688a5a2 ec/google/wilco: Add ACPI SuperIO devices
Add ACPI devices for the basic SuperIO functionality provided by the EC
for PS/2 keyboard, PS/2 mouse (trackpad emulation), and legacy UART.

The specific defines to enable these devices should be declared by the
mainboard before including this ASL, the same as the Chrome EC behavior.

4af38d440d ec/google/wilco: Add ACPI battery and AC objects
Add the expected objects (_BST, _BIF, _BIX) for reading battery
information and status from the embedded controller, and the
expected objects for reporting AC power status.

The battery was tested by booting with a battery attached and checking
that it is present in /sys/class/power_supply/BAT0 and that the values
are consistent and within expected ranges.

The AC device was tested by checking the AC status in sysfs when AC
is inserted or removed while the system is running.

a802be2910 ec/google/wilco: Add ACPI EC infrastructure
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.

ea98b40efe ec/google/wilco: Add a bootblock function for early init
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.

21dde8b25f ec/google/wilco: Add Wilco EC mailbox interface
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.

ecf6531c47 ec/google/chromeec: Define a sync IRQ 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.

================================================================================

ADVICE: (for Warning #3115, ASL_MSG_RETURN_TYPES): Some of the execution paths
do not return a value. All control paths that return must return a value
otherwise unexpected behaviour may occur. This error occurs because a branch on
an conditional op-code returns a value and another does not, which is
inconsistent behaviour.

_Q09 is a reserved method and can't return a value. Change the logic
so that no return is used and avoid this test error.

BUG=b:112476331
TEST=Run FWTS.

bd21f2844b chromeec: Read EC uptime info on boot
Additional diagnostic information about the EC and the most recent
reasons why it has reset the AP are read out and logged via printk.
This may aid in debugging spurious hangs and/or resets on the AP by
providing traceability to the EC when it triggered the reset.  Merely
knowing that the EC was also recently reset may provide valuable
intelligence.  See also https://crrev.com/c/1139028.
