af4c0a431c ec/ene_kb3940q: correct ACPI battery data fed into ToString()
ToString() requires the input buffer data to be null-terminated,
but the data returned by the EC is not, leading Windows to fail
to report any battery data at all.  Correct this by concatenating
a null terminator (0x00) to the end of the buffer data before
inputting to ToString() where needed

TEST: boot Windows on google/butterfly, observe battery data
reported correctly.

2ac86c37b2 ec/google/chromeec: Fix typo in ECUI device
The IO region defined for EC_HOST_CMD_REGION1 was incorrectly
using EC_HOST_CMD_REGION0 for the range maximum so the region
was showing a minimum of 0x880 and a maximum of 0x800.

Both min and max should report the same value as this region
is fixed and cannot be relocated by the OS.

f63fbdb63a mb/lenovo/x201: Add support for ThinkLight
The thinkpad-acpi driver uses the UCMS (CMOS) ACPI method to control the
ThinkLight from the Operating System. This patch adds partial support for
that method, enough to enable or disable the ThinkLight:

echo on >/proc/acpi/ibm/light
echo off >/proc/acpi/ibm/light

With the original BIOS the UCMS method exposes a wide range of values
through a generic /proc/acpi/ibm/cmos interface. With the changes suggested
in this patch that interface is also exposed but only accepts the commands
to enable or disable the ThinkLight; all other commands are ignored.

This change would potentially benefit all currently supported Thinkpad
models, I only have an X201 available for tests though.

58c3938705 vboot: Move remaining features out of vendorcode/google/chromeos
This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

Currently, when using `iasl` 20140926-32 [Oct  1 2014] from Debian 8

ASL 2.0 supports `<<`. For consistency, right now, coreboot still uses
the old syntax. So use `ShiftLeft` instead, which also fixes the build
issue with older ASL compilers.

068edc1c52 ec/lenovo/h8: Fix mute LEDs
thinkpad_acpi expects a SSMS method to turn on/off the mute LED
and a MMTS method to turn on/off the microphone mute LED. With
these methods implemented the driver can correctly sync the LEDs
with the corresponding statuses.

There seems to be two different bits to mute the audio in the
Lenovo H8 EC:
 * AMUT, used internally (for example to disable the audio before
    entering S3).
 * ALMT, controllable by the OS, which also toggles the mute LED
    (if present).

Tested on a X220T and on a X201.

9b798d7904 ec/lenovo/h8: Guard against EC bugs in the battery status logic.
On my Thinkpad with an H8-compatible ENE KB9012 EC (GDHT92WW 1.52), when
the battery is nearly full and we switch from battery to AC by plugging

discharging state is cleared immediately.

This leads to the code trying to process an invalid rate value >0x8000,
leading to a displayed rate of >1000W.

This patch changes the logic to deal with these corner cases.

96a4317fa9 ec/google/chromeec: let platform prepare for reboot when resetting EC
This fixes an issue on systems where the S3 state in the pm1 control
registers are not cleared when vboot determines recovery mode is
required on an S3 resume. The EC code will reboot the system knowing
that the EC was in RW. However, on subsequent entry into romstage the
S3 path will be taken and fails to recover cbmem -- forcing another
reboot. To work around that, signal to the platform a reboot is
happening and let the platform perform the necessary fix ups to the
register state.

(bits 2 and 3) is the configuration field. According to Peter Stuge,
AOCF can be configured in this way:

    00 => AC S3 S4 S4 USB on, battery S3 USB on, battery S4 S5 off
    11 => AC S3 S4 S4 USB on, battery S3 S4 S5 USB off
    10, 01 => equivalent to 00

This commit also adds a new configuration field in the CMOS of the
X220 and the X201 to activate this feature. It probably can be also
added to all the ThinkPads that support this functionality.

With this functionality USB devices are able to negotiate full power
from the dedicated port (usually the yellow one) even in S3.

Tested on a X201 and X220 with an Android smartphone: with this
feature enabled it shows "Charging" when connected during S3, without
it it shows "Charging slowly" (or it doesn't charge at all on the
X201).

For some reasons the "AC only" mode doesn't work, so it has been
disabled.

cd2afc0df0 google/chromeec: Add common infrastructure for boot-mode switches
Instead of defining the same functions for reading/clearing boot-mode
switches from EC in every mainboard, add a common infrastructure to
enable common functions for handling boot-mode switches if
GOOGLE_CHROMEEC is being used.

Only boards that were not moved to this new infrastructure are those
that do not use GOOGLE_CHROMEEC or which rely on some mainboard specific
mechanism for reading boot-mode switches.

BUG=None
BRANCH=None
TEST=abuild compiles all boards successfully with and without ChromeOS
option.

6444b52ce0 Revert "ec/lenovo/h8: don't load configuration when booting from s3"
This reverts commit 83df672d2c.

It's based on the assumption that the H8 keeps its configuration
during a suspend/resume cycle. User reports indicate that this might
not be true.

Caching the settings in a cbtable entry might be a better approach.

Kconfig hex values don't need to be in quotes, and should start with
'0x'.  If the default value isn't set this way, Kconfig will add the
0x to the start, and the entry can be added unnecessarily to the
defconfig since it's "different" than what was set by the default.

A check for this has been added to the Kconfig lint tool.
