When TOT link moved to 128KB images, I missed two references to 80KB. Fix those, so TOT now builds 128KB images for all lm4-based platforms. BUG=chromium:252584 BRANCH=none (link branch will stay at 80KB images) TEST=sysjump rw doesn't crash Change-Id: I5f25cf97ec706374d03ce8ecff6572c1c84242b5 Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/60153 Reviewed-by: Duncan Laurie <dlaurie@chromium.org>
- 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.
=== EXCEPTION: 03 ====== xPSR: 01000000 ===========

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_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.
- CONFIG_PMU_FORCE_FET
Force switching on and off the FETs on the PMU controlling various
power rails during AP startup and shutdown sequences.
This is mainly useful for bringup when we don't have the corresponding
sequences in the AP code.
- CONFIG_KEYBOARD_TEST
Turn on keyboard testing functionality. This enables a message which
received a list of keyscan events from the AP and processes them.
This will cause keypresses to appear on the AP through the same
mechanism as a normal keyboard press.
