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.

On s3 wakeup h8_enable is called which resets the (audio) volume. But the
volume should be the same as before the s3 state. In particular, userland
programs (e.g. pulseaudio) may be out of sync, if the volume can be changed
by hardware buttons also emitting acpi events. Hence, do not reset the

On certain Winbond SuperIO devices, when a PS/2 mouse is not
present on the auxiliary channel both channels will cease to
function if the auxiliary channel is probed while the primary
channel is active. Therefore, knowledge of mouse presence
must be gathered by coreboot during early boot, and used to
enable or disable the auxiliary PS/2 port before control is
passed to the operating system.
Add auxiliary channel PS/2 device presence detect, and update
the Winbond W83667HG-A driver to flag the auxiliary channel as
disabled if no device was detected.

This adds basic ACPI support for the EC used on Purism Librem laptops.

support in the linux kernel for handling the special keys.
Supported functions:
- Battery information
- AC presence
- Lid switch
- Special keys (after loading topstar-laptop driver in linux)
- EC events for turbo enable/disable when on AC power
Things it does not do:
- EC SMI handling
- Fan is left under EC control
This was developed and tested on a Librem 13 laptop, and has not
been directly tested on an Librem 15.

However, we got confirmation that we don't have to update

util/kconfig is excluded because that's imported code that

This patch adds a few retries to NVRAM read/write transactions with the
EC. Failing to read the NVRAM is not fatal to the boot, but it's still
pretty bad... especially since a single initial read failure will cause
vboot to blindly reinitialize the whole NVRAM with zeroes, destroying
important configuration bits like dev_boot_usb. The current EC
transaction timeout is one second, so the three retries added here can
potentially increase boot time by three seconds per transaction... but
this shouldn't happen in any normal case anyway, and if there are errors
a little extra wait is probably preferrable to nuking your NVRAM.
(Also, added a missing newline to an error message in the EC code.)

The new API is in use in depthcharge and is based around the "i2c_transfer"
function instead of i2c_read and i2c_write. The new function takes an array of
i2c_seg structures which represent each portion of the transfer after a start
bit and before the stop bit. If there's more than one segment, they're
seperated by repeated starts.
Some wrapper functions have also been added which make certain common
operations easy. These include reading or writing a byte from a register or
reading or writing a blob of raw data. The i2c device drivers generally use
these wrappers but can call the i2c_transfer function directly if the need
something different.
The tegra i2c driver was very similar to the one in depthcharge and was simple
to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and
replace the ones in coreboot. The Exynos 5420 driver was ported from the high
speed portion of the one in coreboot and was straightforward to port back. The
low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot
and were replaced with the depthcharge implementation.

The SPI drivers for tegra and exynos5420 have code in them which waits for a
frame header and leaves filler data out. The SPI driver shouldn't have support
for frame headers directly. If a device uses them, it should support them
itself. That makes the SPI drivers simpler and easier to write.
When moving the frame handling logic into the EC support code, EC communication
continued to work on tegra but no longer worked on exynos5420. That suggested
the SPI driver on the 5420 wasn't working correctly, so I replaced that with
the implementation in depthcharge. Unfortunately that implementation doesn't
support waiting for a frame header for the EC, so these changes are combined
into one.

There were instances of unneeded arch/hlt.h includes,
various hlt() calls that weren't supposed to exit (but
might have) and various forms of endless loops around
hlt() calls.
All these are sorted out now: unnecessary includes are
dropped, hlt() is uniformly replaced with halt() (except
in assembly, obviously).

The in source comment:
/* This function avoids an error on serial console. */
refers to the resource allocator needing to find a non-NULL
function pointer else complaints of "... missing read_resources"
will be spewed.
Unfortunately/fortunately (depending on the time of day) compiler
optimisers have gotten a bit better at optimising away no-op functions
leading to the very message these stubs attempted to avoid. By using
the DEVICE_NOOP formalism that is static inlined 'suggests' (not enforces)
to the compiler to keep these symbols around.

This patch renames the x86 way of doing things to
explicitly mention CMOS (which is not available on
our ARM platforms) and adds an implementation to
get VBNV through the Chrome EC. We might want to
refine this further in the future to allow VBNV
in the EC even on x86 platforms. Will be fixed when
that appears. Also, not all ARM platforms running
ChromeOS might use the Google EC in the future, in
which case this code will need additional work.

Remove guarding the inclusion of headers based on CONFIG_ options. This
*potentially* could hide issues such as functions being swapped from

the same function same name and type-signature. Hence, depending on the

Add the new Chrome EC protocol version 3 to Coreboot.
Note, protocol version 3 is not applied on any bus implementations yet.
LPC (x86) and I2C (arm/snow) are still using v2 protocol. The first one to use
v3 protocol will be SPI bus (arm/pit). LPC / I2C will be updated to v3 only
when they are ready to change.

Since EC protocol v3, the packet format will be the same for all buses (inclding
I2C, SPI, and LPC). That will simplify the implementation in each individual bus
driver source file.
To prepare for that, we will move the protocol part into crosec_proto.c:
crosec_command_proto, with bus driver in callback "crosec_io".

The LPC-based ChromeOS EC uses several ioport regions to communicate with
the AP. In order for the new unified userspace access method to work, we
need them to be reserved by the BIOS.
Before /proc/ioports shows:
0800-0803
0804-08ff
We'd like just a single 256-byte region at 0x800, but ASL can't handle that.
So this will work:
0800-087f
0880-08ff

Now that we are executing VbInit() in coreboot we can end up
in a situation where the recovery reason is consumed during
VbInit (end of romstage) and then the EC is rebooted to RO
during ramstage EC init, thereby losing the recovery reason.
Two possiblities are to remove the EC check+reboot from ramstage
and let it happen in depthcharge. This however means that the
system has to boot all the way into depthcharge and then reboot
the EC and the system again.
Instead if we do a check in romstage before VbInit() is called
then we can reboot the EC into RO early and avoid booting all
the way to depthcharge first.
This change adds a ramstage version the EC init function and
calls it from the shared romstage code immediately after the
PCH decode windows are setup.
