fa643a9fc7 cr50: add support for creating multiple serial endpoints
CR50 will need three serial endpoints for the streaming AP and EC UART
and exporting its own console through USB. This change adds a macro to
create endpoints that can be recognized by the usb_serial driver.

99f62cb3a9 common: Adds a JEDEC SFDP v1.* based Serial NOR Flash driver
Adds a JEDEC SFDP v1.* compatible Serial NOR Flash driver to control
multiple Serial NOR Flash devices (NOR EEPROMs, etc.). The SFDP tables
are used to discover parts' page sizes and capacities.

This driver only supports parts with capacities under 4GiB. If the
parts are larger than 16MiB, then the 0xB7 4-Byte addressing mode
entry opcode and 0xE9 4-Byte addressing mode exit opcode are required.
This driver also assumes that a 4KiB erase opcode of 0x20 is always

ae89bb6f49 cr50: SHA1 and SHA256 implementation with hardware support
This change includes hardware and software support for SHA1/256 on
CR50. When running in the RO image, only hardware sha256 support is
included. When running in the RW image, the code auto-selects between
the software and hardware implementation. Software implementation path
is taken if the hardware is currently in use by some other context.

Refactor the CR50 loader to use this abstraction.

The existing software implementation for SHA1 and SHA256 is used for
the software path.

16a18a5e0e driver: Refactor Kionix Accelerometer drivers.
This commit adds a new basic driver for the Kionix KX022 Accelerometer.
Currently, the driver is capable of reading the sensor data and
manipulating its ODR, resolution, and range.

This sensor also has integrated support for Directional
Tap/Double-Tap(TM), however that functionality is not yet implemented in
the driver.

Lastly, since this accelerometer is very similar to the previous KXCJ9,
this commit tries to combine the drivers.

Note, the variant of the Kionix accelerometer MUST be specified in the
private data structure.

15135076e2 Cr50: Enable TPM-protocol data over the SPI bus
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.

bd7e885ae7 Stream: Remove in_stream/out_stream interface
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
test echo code from the discovery-stm32f072 board and updating
the mcdp28x0 driver to use the queue interfaces).

855646e36b Producer/Consumer: Refactor to use Queue policies
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.

7c1231c55f pd: initial split of protocol code to create port controller
Initial split of the USB PD protocol code to create the new port
controller (TCPC) and port management (TCPM) blocks. The intention
is that the TCPC code will eventually reside on a different MCU,
along with the USB PD phy layer. The TCPM will stay with the protocol
and policy layers and provide a standard interface to TCPC (over
i2c).

As a first step, this CL merely splits up the files and directly
calls functions to reach across between TCPM and TCPC.

746debdf20 spi_flash: Rework protection translation functions
Previously we defined separate functions to map registers to protect
ranges for each supported SPI ROM. This change instead adds a protect range
table + flags for each supported SPI ROM and adds common functions for
translation between ranges + registers. This makes supporting new parts
easier. Since we will never use most supported protection ranges, we can
even simplfy the tables.

The implementation is now similar to flashrom.

1a0235e69f Streams: Define a lower level abstraction for queue access
This adds a new pair of interfaces called producer and consumer
which are simpler (in that they don't hold onto the underlying
queue) than the stream interfaces.  This makes it easier to
share a single queue between the endpoints that will manipulate
it.  It was not possible to share a queue between two objects
that implemented the in_stream and out_stream interfaces.

This also adds a pair of adaptors that can convert a producer
or consumer into a stream of the correct type.  These adaptors
will be used for existing code once the usb-stream and usart
drivers are converted over to use the producer/consumer
interfaces instead of the stream interfaces.

b8f73a451d charge_manager: Add module for managing battery charge limits
charge_manager is intended to manage charge limits from various tasks
(typically PD charge tasks and USB / BC 1.2 charge tasks). These tasks
can update the charge limit of a port by calling charge_manager_update
(thread-safe function). If the charge limit has changed,
charge_manager_refresh will be queued as a deferred task, which will
select the "best" charge port and set the proper charge limit.

In order to use charge_manager, a board needs to do the following:

1. Declare PD_PORT_COUNT in usb_pd_config.h
2. Implement board_set_charge_limit
3. Implement board_set_active_charge_port
4. Call charge_manager_update whenever the available charge on a port changes.

BUG=chrome-os-partner:31361
TEST=Manual on samus_pd, with subsequent commit. Insert and remove
various chargers, check console to verify PD charger always has priority
and correct current limit is set based upon 'best' charger.
