ap_state doesn't disable/enable the detect ap interrupt correctly. This
means cr50 is mostly just polling the AP state. Cr50 may not realize the
AP is up until almost a second after it first turned on. This change
reenables the detect ap on interrupt while debouncing the AP state or if
Cr50 thinks the AP is off, so cr50 can more quickly detect the
transition from off to on.
This issue doesn't affect devices that detect the AP with TPM_RST_L,
because we never disable the TPM_RST_L interrupt and that handler calls
ap_on_deferred directly.

pwr_avg provides an average voltage, current, and power over the last

This change allows us to have better power tracking while minimizing
the power impact on the EC, because
- the pwr_avg command only needs to be called once every minute, and is
short, thus less expensive to parse on ECs without a UART buffer
- the work done to keep the avg is partially done by the batteries
already and it's just a question of retrieving it.

After a call to pthread_create(), it is indeterminate which thread the
caller or the new thread will next execute. Synchronize with the new
thread and allow it to initialize (and print to console, before the
print can potentially interfere with other prints) before proceeding.

Cr50 should not automatically touch the EC reset when enabling the
USB-EC SPI bridge. Otherwise, this could interefere with ECs that might
have internal SPI flash and need to have their resets deasserted in
order to access the internal SPI flash.
This commits simply removes the assertion of EC reset when enabling the
USB-EC SPI bridge. The user or external scripts should control the
resets as necessary using servo or the cr50 console.

Current revision of nautilus boards will lose VBAT on power cycle and
therefore cannot successfully save the reset flag state.
Implement workaround that will allow boards to continue to work for
FAFT testing by indicating to the skylake chipset power code that it
could skip the PMIC reset when doing 'reboot ap-off'.

Enable deep sleep on rk3399 devices and start using SYS_RST_L to track
the AP state.
We can only release this once the EC has the proper support. It needs to
assert SYS_RST_L in S5.
If we have an old EC and this change in the Cr50 firmware, Cr50 won't be
able to tell when the AP is off. I think this will just cause an
interrupt storm on the AP UART and might not go into regular sleep in
S5.
If the EC change gets released before Cr50, Cr50 won't go to sleep in
S5, because SYS_RST_L is a wake on low pin. Cr50 will immediately wake
up from the SYS_RST_L pin when it enters sleep.
