1) Don't assert prochot by default, this signal has an inverter
and driving it high is asserting prochot until it gets deasserted
during S3->S0 transition.
2) Clear PMIC power source interrupts in pmic_init in case they
were inadvertently set by misbehaving PMIC. The BATTSHORT event
that matters for PROCHOT assertion is masked so it should never
be set anyway, but I found a system where it was set. This register
does not seem to get cleared by an LDO reset so PROCHOT was stuck on
until battery cutoff.

This adds the CCD configuration module, and the console commands to
control it. It is not wired up to any of the CCD capabilities; that's
coming in the next CL.
Briefly:
* CCD configuration is persistently stored in nvmem_vars. Use ccdinfo to
print it.
* CCD can be Locked, Unlocked (some capabilities), or Opened
(all capabilities), using the ccdlock / ccdunlock / ccdopen commands.
* CCD config can be restricted by setting a password via ccdpass.
* Individual config capabilities can be set via ccdset. Some of those will
be used to gate access to things like write protect and UARTs. Others
affect the requirements for ccdunlock / ccdopen (for example, is physical
presenc required).
* The entire config can be reset via ccdreset. If only unlocked, config
that is restricted to Opened is not reset.
* If CR50_DEV=1, ccdoops will force-reset and open the config.
See go/cr50-ccd-wp for more information.

This will be used as part of case closed debugging configuration.
Currently, this only adds the state machine, and a test command which
is available when CR50_DEV=1. It also adds a new sleep mask flag for
physical presence detect, instead of oveloading FORCE_NO_DSLEEP.
The physical presence state machine supports both short (tap 5 times
in 15 seconds) and long (short, followed by 4 more taps 1-5 minutes
apart) sequences. It will call a callback function at the end of the
sequence, so that multiple things can each request physical presence
in turn. This will be used by ccdopen / ccdunlock / testlab commands
for CCD V1.
Eventually, CCD config will replace the unlock sequence handling in
wp.c. But for now, we don't touch that.

Newer boards (version > 4) will behave as expected.

which steps from one color (some RGB combo) to another gradually. When
the new or old color is white, then precomputed steps computed from
HSI space are used. Other transisions involving either just red/green
use linear steps computed dynamially based on the total change.
This CL also creates a new task for the LED code so that the color
transitions won't hold off other hook tasks for too long a period of
time. Changed the LED tick time to be 500 msec as it's no longer tied

Implement U2F (universal second factor authentication) feature
over TPM vendor commands.
The raw U2F APDU as defined by the FIDO Alliance 'U2F Raw Message Formats'
specification can be sent using the VENDOR_CC_U2F_APDU command.
So the vendor command is taking a ISO7816-4:2005 APDU format frame as input
as defined by the spec and returns another APDU using ISO7816-4 status
code.
The APDU is processed by the common U2F code using u2f_apdu_rcv(),
this hardware specific code provides:
- the user physical presence detection (done by the power button press)
returned by the pop_check_presence() callback.
- the connection to the cryptographic hardware to generate/derive the
keys used by the U2F and individual attestation functions.
This feature/vendor command has 3 modes:
- disabled
- U2F (only the commands/flags defined by the U2F specification)
- G2F (the U2F commands plus some extensions for individual attestation)

The Eve board defines left and right LEDs, but the LED control loop is
checking for auto control to be disabled on the power/battery LED IDs.
This is breaking factory testing for LED colors when the battery level
is low because it is flashing RED and ignoring the colors that the
factory software attempts to set.

The INFO1 mask field contents serves as input for the rollback
protection mechanism, when the RO decides if an RW is allowed to run
on the device.
The existing code updates INFO1 mask to match the lowest rollback
priority of the two images (RW_A and RW_B) present on the device.
INFO1 mask should be also updated when the current image is endorsed
by the host. In this case the alternative RW is destroyed, so the
INFO1 mask could be set based solely on the currently running image.
This patch refactors the code to allow setting INFO1 mask based on one
or both RW headers' contents.
BRANCH=cr50
BUG=b:62138152
TEST=verified that "normal" INFO1 mask updates still work as before,
the mask is modified to match the image with the lowest rollback

currently running image.
