bb15561db5 cleanup: DECLARE_CONSOLE_COMMAND only needs 4 args
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.

and EC is eligable to enter heavy sleep idle task.
Wakeup from S0ix by lid open, any key press, power button or track pad
will be done by PCH block by asserting SLP_S0.

823d3a2d51 ec_commands: Add "hibdelay" as an EC host command.
Currently, the only way to prevent a system from hibernating is via the
EC console command "hibdelay".  This commit adds the host command
equivalent so that it can be set elsewhere.  The host command takes the
amount of time in seconds to delay hibernation by and responds with the
current time in the G3 power state, the time remaining before
hibernation should be invoked, and the current setting of the
hibernation delay.

60ddb3987a samus: change hibernate delay to 7 days
Add macro for default hibernate delay, and set to 7 days on samus.

Added ccprintf("Target shutdown: %.6ld\n", target_time); to print

1) If CONFIG_HIBERNATE_DELAY_SEC is left at default 3600 (samus
board.h does not overwrite it), then target time is 3600s.
2) If CONFIG_HIBERNATE_DELAY_SEC is defined in samus/board.h, then
target time equals that value.
3) If CONFIG_HIBERNATE_DELAY_SEC is defined as 1 week and
CONFIG_HIBERNATE_BATT_PCT is defined to 10% and
CONFIG_HIBERNATE_BATT_SEC is 1 day, then when battery is between 8-10%
target time is 1 day and if battery is at 11%, target time is 1 week.

565f1cb5ae Add CONFIG_BRINGUP option to help debug signals for bringup
When this option is configured, two changes take place.

First, the AP doesn't power on by default when the EC reboots. To boot it,
you can run the "powerbtn" command, or poke the power button manually, or
any of the normal things.

Second, we watch for power-related signal changes (anything that's connected
to the power_signal_interrupt() function) and keep track of them as they
happen. After a second with no further changes, we print the time and value
of each change. For example:

ffac23c0ea Add cprints() and ccprints()
Our code base contains a lot of debug messages in this pattern:
  CPRINTF("[%T xxx]\n") or ccprintf("[%T xxx]\n")
The strings are taking up spaces in the EC binaries, so let's refactor
this by adding cprints() and ccprints().

cprints() is just like cprintf(), except that it adds the brackets
and the timestamp. ccprints() is equivalent to cprints(CC_CONSOLE, ...)

This saves us hundreds of bytes in EC binaries.

We don't have available GPIO pin for power button as the hibernate

So, put the EC in a decent infinite loop to pretend the hibernate mode
and wait for particular wake-up event. This should be fine because
the AP is already down before EC hibernates.
