This patch adds a module which runs on top of the SPS driver and
implements the TCG SPI TPM protocol.
Basic register read and write functions are implemented as well as
rudimentary TPM state machine (claiming/releasing locality).
An enhancement is made to the SPS driver to ensure that when the CS is
deasserted the transmit FIFO is reset too, on the off chance of the CS
going away mid transaction for whatever reason.
In this implementation the slave is guaranteed to stall the master for
a few bytes in both receive and transmit transactions, which is
further aggravated by the fact that RX FIFO threshold is set to 8
(this is the minimum number of bytes the master has to send to wake up
the slave). This could be fine tuned later, for instance made a
parameter of the receive callback registration function.

The in_stream and out_stream interfaces were a first attempt
at providing an abstraction for multiple stream like devices
(usart, USB, I2C/LPC host interfaces...). But, by baking
the queue into the device it proved to be hard to use and
required additional resources (task or deferred hook) to handle
passing data from one stream to another.
Since then the queue policy and producer/consumer interfaces
have replaced the stream interfaces. This CL removes the old
stream interfaces and updates the only users (deleting the

Previously the Producer and Consumer interfaces tracked the
Consumer and Producer respectively at the other end of the
queue that they interacted with. This was done to avoid
modifying the queue implementation, but resulted in a rougher
interface that required additional initialization steps and
prevented alternative configurations; many producers and one
consumer for example.
This commit uses the new queue policies to track this
information. The new direct policy behaves as the old producer
and consumers did. Now the producers and consumers are just
named references to the queue that they work on and a convenient
location for a notification callback when the queue is updated in
a way that is relevent to the producer or consumer.
All users of Producer and Consumer have been updated including the
stream adaptors which are in use by the echo test code and the
mcdp28x0 driver. Use of the stream adaptors has also been
simplified.

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.

Imported code from VBoot firmware cryptolib and slightly reformat it for
the EC code base.
We already have SHA-256, but for updates over PD, the maximum payload
size is 192 bits, so SHA-1 seems a better trade-off.

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).

This command wedges the I2C bus by writing part of a byte to or reading part
of the response from the slave device.
To enabled the wedge command you must define CONFIG_CMD_I2CWEDGE and you must
define I2C_PORT_HOST, the i2c port to use the wedge command.
BUG=chrome-os-partner:19286
TEST=Manual test on peach pit, spring, and glimmer. Define config in board.h
to enable the command:
On the EC console, execute the following "i2cwedge" command
i2cwedge 0x90 0 1 (wedge write)
or
i2cwedge 0x90 0 2 (wedge read)
and then "battery". Observe that the command reports an error.
Similarly, execute
i2cwedge 0x90 0 5 (wedge write + reboot)
or
i2cwedge 0x90 0 6 (wedge read + reboot)
on the EC console and observe a reboot. Then execute "battery" and observe
that the command works properly.

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.

To test, you'll need a reworked and correctly programmed capsense module.
