68abc0f428 watchdog: Give more leeway to the independent watchdog
It would be really nice to be guaranteed to see watchdog warnings
before we actually hit a watchdog reset even if something strange is
going on with the CPU.  Let's increase the margin between the timer
and the independent so that the hardware watchdog is really hit as a
last resort.

It seems like a 1.6 second hardware watchdog wouldn't be the end of
the world so let's bump that way rather than increasing the number of
warnings.

4702a1d19b watchdog: Help ensure that the stm32 watchdog help prints
On stm32 we were programming the WATCHDOG_HELP timer with the same
value as the independent watchdog (which automatically resets the
CPU).  That means we weren't guaranteed to see the WATCHDOG_HELP.  It
happened to work most of the time due to the the LSI oscillator fudge
(we assumed the watchdog was on a 56 kHz oscillator when it was
probably on a 38 kHz one), but let's give ourselves a guaranteed gap.

It's unlikely that this extra gap will actually help on most machines
(if we're running at 53 kHz or lower we already had this much margin),
but it's nice to be safe.

0d0b53e7ca zinger: change watchdog timeout to 1.8 second
Increase watchdog timeout to 1.8 second. The pd_task can delay up
to 1.5 seconds, so the watchdog must be at least that value.
On Zinger, the new timeout period will be 2 seconds with LSI clock at 50kHz

Note: the LSI frequency range is tighter on STM32F0 and cannot go up to
56kHz.

2478058b7a Emit error when board.h or config_chip.h is included before config.h
If board.h or config_chip.h is included before config.h, CONFIG_* flags
may be incorrect. For example, if config.h says:

    ...
  #define CONFIG_DEFINED_FLAG
    ...
  #include "board.h"
    ...

And board.h says:

  #ifndef __BOARD_H
  #define __BOARD_H
    ...
  #undef CONFIG_DEFINED_FLAG
    ...
  #endif

Then this code:

  #include "board.h"
  #include "config.h"

would results in CONFIG_DEFINED_FLAG being defined, instead of undefined
as stated in board.h.

Avoid this by emitting error when board.h or config_chip.h is included
before config.h.

72357cd1ed samus: Allow samus to charge w/o battery or with dead battery
Use a EC to PD host command to notify the PD MCU when a battery
is present and charged enough that it is ok to negotiate for a
higher power. The PD MCU will not negotiate until the host command
is received, which allows the system to be powered without a
battery or with a dead battery with 5V.

BUG=chrome-os-partner:28611
BRANCH=none
TEST=Tested on a samus:

1) Tested the normal case of battery charged and plugged in. When
charger is plugged in, the device immediately starts negotiating
for 20V and starts charging.
2) Tested with no battery. Plug in a charger, samus boots and stays
alive. VBUS measured at 5V. When a battery is plugged in, device
negotiates for 20V and starts charging.
3) Tested dead battery by taking a battery with no charge, and
plugging in zinger. Everything boots, but PD does not negotiate
for power. Then when battery reaches 1%, PD negotiates and zinger
switches to 20V without causing a reboot.

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:

242f195771 rambi: glimmer: Disable key scanning in suspend when lid is open
Added ability to disable the keyboard to wake from suspend when the lid
is outside a certain angle range. This has been added to glimmer by
defining CONFIG_LID_ANGLE_KEY_SCAN in its board.h.

Also modified the lid angle calculation to include a reliability
flag which can be used to tell when the hinge aligns too closely
with gravity and the lid angle value is unreliable.

BUG=none
BRANCH=rambi
TEST=Tested on a glimmer:

In S3, verified that when the lid is open past ~180 deg, the keyboard
does not wake the machine. Also verified that if you align hinge with
gravity, the keyboard enabled/disabled status remains the same (since
we can't actually trust the lid angle value).

6f2869903d rambi: Add motion sense task to track motion
Added motion sense task to Clapper and Glimmer. This task samples
the accelerometers and calculate a lid angle. Note that as
the machine is rotated towards the hinge angle aligning
with gravity, the lid calculation becomes less trustworthy.

Added a math_util file to hold various mathematical functions
useful for calculating lid angle that may be helpful in other
places.

For each board with accelerometers we need to define some
orientation specific data in board.c. There is a calibration
procedure through the EC console that can be enabled by
defining CONFIG_ACCEL_CALIBRATE. The calibration procedure can
help determine the orientation data required.

For debugging purposes there is a console command to regularly
print to the EC console the accelerometer data and derived lid
angle. The console command can be enabled by defining
CONFIG_CMD_LID_ANGLE.

72481572aa Convert vboot hash calculation from task to deferred function
Vboot hash calculation takes ~350 ms during EC boot.  Since the hash
task is higher priority than the hook task, this starves all the hooks
during boot.

We could, in theory, fix that simply by swapping the priority of the
hook and hash tasks.  But then watchdog detection (in the hook task)
wouldn't detect hangs in the hash task.

A better fix (implemented here) is to convert the hashing operation to
a series of deferred function calls.  This gets rid of the hash task
entirely, and allows all pending hooks and other deferred function
calls to take place between each chunk of hashing.

On STM32-based boards, we need to bump up the hook task stack size,
since hashing is called from several layers deep in the hook task
instead of at the top of its own task, but this is still a net win of
several hundred bytes of SRAM.

BUG=chrome-os-partner:24892
BRANCH=rambi
TEST=Boot EC; look for "hash start" and "hash done" debug output.
