627f3a8ac2 KBL/SKL: Add wait between DSW_PWROK and PWRBTN
This patch adds wait between DSW_PWROK and PWRBTN assert. It is
required to be 95 msec or longer for Kaby Lake and Sky Lake.
Refer to the timing diagram for G3 to S0 on Sky Lake or Kaby Lake
platform design guide for details.

BUG=b:62584658
BRANCH=none
TEST=On Fizz, measured time between DSW_PWROK high and PWRBTN assert
for 1:AC plug-in, 2:recovery+power press, 3: reboot ec command.

98dc270b23 power_button_x86: Save and restore power button pulse setting
This change ensures that the power button pulse setting is saved and
restored across a sysjump. It uses the SYSJUMP_TAG "PB" (0x5042).

BUG=b:62445190
BRANCH=None
TEST=The condition mentioned in the bug could be reproduced using
following steps:
1. reboot on EC console
2. Use Vup/Vdn to select any option other than Power off.
3. Press power button

After step #3 above, device would shut down instead of selecting the
option. Verified that with this change, the device does not power off
anymore at step #3.

e8982ea3cd Allow lid-less configuration

patch separate them so that a board with power button but with no

This patch also moves backlight control to the board directory

0af6e77a3a charger: Change unlocked battery level ignore conditions
x86 systems will auto-power-on when power is applied to the EC. When
the battery level is critically low, power-on is prevented, except when
the system is unlocked. So, when unlocked, some systems will
auto-power-on regardless of battery level, overcurrent the charger /
battery, and then repeat forever.

Prevent this reboot loop by ignoring auto-power-up when the battery is
critically low, regardless of system unlocked status.

565f1cb5ae Add CONFIG_BRINGUP option to help debug signals for bringup
When this option is configured, two changes take place.

First, the AP doesn't power on by default when the EC reboots. To boot it,
you can run the "powerbtn" command, or poke the power button manually, or
any of the normal things.

Second, we watch for power-related signal changes (anything that's connected
to the power_signal_interrupt() function) and keep track of them as they
happen. After a second with no further changes, we print the time and value
of each change. For example:

ffac23c0ea Add cprints() and ccprints()
Our code base contains a lot of debug messages in this pattern:
  CPRINTF("[%T xxx]\n") or ccprintf("[%T xxx]\n")
The strings are taking up spaces in the EC binaries, so let's refactor
this by adding cprints() and ccprints().

cprints() is just like cprintf(), except that it adds the brackets
and the timestamp. ccprints() is equivalent to cprints(CC_CONSOLE, ...)

This saves us hundreds of bytes in EC binaries.

dd702e8447 baytrail: Workaround for stuck boot process
In some cases, the system will boot to S0 from the point of view of
the EC, but PLTRST# will never deassert.  Work around this by waiting
50 ms for PLTRST# to deassert.  If it doesn't, force the chipset all
the way down by deasserting RSMRST#, then pulse the power button to
turn it back on.

Also add a powerfail debug command to simulate this failure event, so
that the recovery process can be tested.

Add API to the LPC module to get the state of PLTRST#, and to the
power button state machine to force it released when we shut down the
chipset and and force another power button pulse as we reset the
chipset.
