- 'port80 intprint' toggles printing port 80 codes in interrupt handler (turning that off speeds up port 80 capture a bit, if you're sending port 80 codes very rapidly) - 'port80 flush' flushes the log buffer - log buffer expanded to 256 entries - log buffer tracks S3->S0 power state transitions, so you can tell where each boot starts This uses ~500 bytes more RAM on the EC, but we've got piles of RAM (with this change we're using 17KB out of 32KB). BUG=none TEST=manual - boot system - port80 -> prints data - port80 intprint -> now disabled - reboot; wait for reboot; no port80 debug output during boot - port80 -> prints data from previous boot AND this one - port80 flush - port80 -> nothing in log Change-Id: I64ee72fb13ab0fdd85d04b9640b5390fdac31400 Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/29420 Reviewed-by: Bill Richardson <wfrichar@chromium.org> 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_NEW_STACK
When reporting a panic, change to a completely new stack. This might
help get a useful trace out a situation where the stack or stack
pointer has been corrupted.
- 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.

- 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
