charge_manager may request a charge current limit less than the
capability of the supply in certain cases (eg. during PD voltage
transition, to make an effort to comply with reduced load spec).
Depending on the battery / system state, setting a reduced charge
current limit may result in brownout.
Pass the uncapped / max negotiated current to board_set_charge_limit()
so that boards may use it instead of the requested limit in such
circumstances.

BRANCH=gru
TEST=Manual on kevin with subsequent commit, boot system with zinger +
low-charge battery, verify devices powers up to OS without brownout.

TPM2.0 needs more NvMem space and currently the whole block is
contiguous in memory with 2 partitions. This CL removes the
requirement that the partitions are in contiguous which allows for 1
partition to placed at top of RW_A and the other at RW_B.
This CL does not change the size of each partition as that will be
done in a subsequent CL.

Since pretty much always, we've declared console commands to take
a "longhelp" argument with detailed explanations of what the
command does. But since almost as long, we've never actually used
that argument for anything - we just silently throw it away in
the macro. There's only one command (usbchargemode) that even
thinks it defines that argument.
We're never going to use this, let's just get rid of it.

The nvmem_write() and nvmem_move() funcitons return an error
if the write or move operation would exceed the user buffer
boundary. However, the TPM2 functions which call these functions
do not check for errors. Instead TPM2 NvMem relies on the return
value of the nv_commit() function to determine if a TPM command
which modifies NvMem succeeds or fails.
This CL adds a nvmem_write_error flag which is set in cases where
an nvmem_write/nvmem_move returns an error. This error flag
is then checked in nvmem_commit() so that the commit operation can
be abandonded and the error returned back up the TPM2 stack.
Tested in full system for two cases.
Installed TPM certificates on the Cr50, then manually erased NvMem with
flasherase 0x7b000 0x5000 and rebooted system. Then on Kevin console
entered the command <trunks_client --own>
NV_MEMORY_SIZE = 9932
NVMEM_TPM_SIZE = 7168
Case 1 -> Without internal write error state, so commit() always
executes if called. In this case, the Kevin console reports
a TRUNKS_RC_WRITE_ERROR and there is a Cr50 reboot.

Case 2 -> Using internal error state to gate the commit() operation.
In this case, the attempted write overflow sets the internal error
state and the commit() following attempted overflow detection is not
exectued. It results in a different AP TPM error shown below as

is that if after failing on the RSA SRK, the ECC SRK write is still

There seems to be flaky issue where the nvmem tests don't fully

happens when I just run this particular test.

The existing algorithm makes several assumptions for a particular
thermistor circuit. This patch introduces a more generic version
that can be used for multiple thermistors on a single board.
The idea is to approximate a curve produced by solving for voltage
measued by an ADC using the Steinhart-Hart equation. For a straight
line one only needs two data points. For a steady curve data
points can be distributed evenly. For the most part, though, data
points should be provided after a significant change in slope.
More data points give more accuracy at the expense of memory, and
we mostly only care about accuracy in the range between "warm"
and "too hot" so only a few data points should be used.

configured for two RW images as well. This CL reports version

The test/tpm_test/tpmtest.py program has been updated to request
the version information at startup, and it also now reports
similar information, just all on one line:
RO_A:* 0.0.2/a3c3d5ea RO_B: 0.0.2/8895c9eb RW_A: cr50_v1.1 ...
The active images are marked with a '*' following the ':', so
that the same regexp can match either format:
($ro, $rw) = m/RO_[AB]:\s*\*\s+(\S+).*RW_[AB]:\s*\*\s+(\S+)/s;

During initialization the NvMem module looks for either a valid
partition or that the NvMem area is fully erased. If neither of
these two conditions were found, then it was only returning an
error code and logging a message to the console.
This CL modifies nvmem_init() so that if the error case as described
above is detected, then it will call nvmem_setup() which will
create two valid partitions. In addition, the setup function
erases all of the existing data in the NvMem space.
Enhanced the unit test that deals with both partitions being
corrupted so that it verifies the version numbers are correct
and that all user buffer data is set to 0xff.

Currently, the matrix keyboard protocol does not have support for
handling non-matrixed keys. This commit adds support for buttons which
do not appear in the keyboard matrix as well as switches.
Additionally, the keyboard FIFO is now just a general MKBP events FIFO
which MKBP events are free to use. Now, buttons and switches wil join
the key matrix event.

Added mutex lock for nvmem write/move operations. In the
current implementation, there is no single entry point
for the platform specific NvMem calls. The mutex lock is
coupled with a task number so that the same task can attempt
to grab the lock without stalling itself.
In addition to the mutex lock, changed where the cache.base_ptr
variable is updated. Previously, this was done prior to the
partition being copied from flash to the shared memory area.
Now, the variable is only updated after the copy so that read
operations will always read from the correctly from either
flash or from cache memory if a write operation has been
started.

If the Cr50 is in deep sleep, it does a full warm boot when it
sees the SPS_CS_L assert. The master doesn't wait for it to
boot (because it doesn't know it has to) and starts clocking in
data bits right away. The Cr50 can't set up the SPS controller
quickly enough to capture those bits, so the first N bits/bytes
are lost and the master keeps clocking, waiting for the SPI
response which it will never get.
To be certain that the Cr50 is awake, this CL causes the
test (master) to assert SPS_CS_L briefly, then wait a little bit
for the Cr50 to wake up from deep sleep (50ms should be plenty),
and THEN it can send the rest of the SPI traffic.
The Cr50 won't enter deep sleep until it's been at least a second
since the last SPI activity, so we don't have to worry about it
going to sleep between SPI commands as long as they're not
terribly far apart.
The kernel driver will have to implement this same hack too,
since the SPI bus doesn't have a suspend/resume protocol like the
USB does. We've known this for some time. It would be nice if
this weren't needed, but it's a hardware constraint.

This adds USB support to Set and Get the Device Configuration.
These control transfers are standard device requests that need to
be added in order to behave properly for USB suspend/resume (and
in general). Before this CL, the Get command always failed and
the Set command had no effect internally. With this CL it works.
Note that this particular change only supports ONE configuration
for the Cr50. If/when we add additional configuration
descriptors, we'll need to update it again.
BUG=chrome-os-partner:50721
BRANCH=none
TEST=make buildall; manual tests on Cr50
This CL includes a test program. Connect the Cr50 to the build
host, and use that program to read and change the configuration.
cd test/usb_test
make
./device_configuration
./device_configuration 0
./device_configuration 1
./device_configuration 2
You may need to use sudo if your device permissions aren't sufficient.

It was observed that the b1 test board falls into bootstrap mode once
the reset button is pressed after a firmware upgrade.
The reason turns out to be that the wrong lead was considered to be
the reset pin, the BIO4, responsible for bootstrapping, was used
instead of the reset pin.
Come to think of it, there is no need to reset the device each time
the FTDI SPI interface is initialized. Let's just drive the bootsrtap
pin to the correct level and not generate the reset pulse at all.
BRANCH=none
BUG=chrome-os-partner:37754
TEST=pressing the reset button on the b1 board now properly restarts
the device.

This extends the test harness with a test verifying firmware upgrade.
The test in fact just determines the area available for upgrade, picks
the appropriate image and sends it to the device, 1K at a time.
The test does not verify that the device in fact switched to the new
image, the test succeeds if the device accepts all update messages.

The ultra debug board uses a different FTDI chip (vid:did 0403:6010),
which has two ports.
The SPI interface on this chip is hooked up to the second port, but
the code indiscriminately uses the first port when trying to open the
SPI channel, on all devices known to it.
Adding a new field in the supported_devices table allows to keep
default behavior, but use port B (the second port) when required.
Also, fix printout formatting problem.

There is no point in defining tpm test exception classes per test
type, one common class is enough, especially if the source module of
the exception is reported.
BRANCH=none
BUG=none
TEST=tried running the test without the USB FTDI cable plugged in, got
the following error message:
$ ./test/tpm_test/tpmtest.py
Starting MPSSE at 800 kHz
Error in tpmtest.py:54: Failed to connect

For some reason the default linker does not find libftdi1 anymore.
Other Chrome OS packages linking to this library still build just
fine, it turns out they are using the default gcc for linking.
Let's do the same for building tpmtest library.
BRANCH=none
BUG=none
TEST=the following sequence now works fine:
cd test/tmp_test
touch *
make
and the resulting library allows to successfully run TPM tests on
the b1 board.
