The TMP006 IR sensors are calibrated against the temperature measured on the *external* side on the casing using a thermocouple stick at the vertical of the sensor. The hinge sensor is sending back strange values, and the Tobject from there should not be trusted. The DC-Jack C-case sensor is not calibrated (and will be removed soon).

- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.

Build Options
=============
- CONFIG_WATCHDOG_HELP
Try to detect a watchdog that is about to fire, and print a trace.
This is needed on STM32, where the independent watchdog has no early
warning feature and the windowed watchdog has a very short period.
- CONFIG_PANIC_HELP
Report extra information about a panic, such as the fault address,
here shown as bfar. This shows the reason for the fault and may help
to determine the cause.

mmfs = 00008200, shcsr = 00000000, hfsr = 40000000, dfsr = 00000008
- CONFIG_ASSERT_HELP
Report assertion failures in a vebose manner to aid debugging. When
enabled an ASSERT() which fails will produce message in the form:
ASSERTION FAILURE '<expr>' in function() at file:line
- CONFIG_CONFIGURE_BOARD_LATE
Define this to call configure_board_late() after initial system init
is complete (and after GPIOs are set up).
- CONFIG_AC_POWER_STATUS
Monitor the state of the AC power input and drive out a GPIO to
the AP indicating this state. The GPIO will be driven low when
AC power is not connected, and high when it is connected. This
uses GPIO_AC_STATUS for this purpose.
