In the interest of making long-term branch maintenance incur as little
technical debt on us as possible, we should not maintain any files on
the branch we are not actually using.
This has the added effect of making it extremely clear when merging CLs
from the main branch when changes have the possibility to affect us.
The follow-on CL adds a convenience script to actually pull updates from
the main branch and generate a CL for the update.

The port 80 task just polls every 1ms until disabled when the system
goes into suspend. Therefore, this commit configures a 1ms timer
interrupt that will be used for the port 80 writes instead of using an
entire task. This saves task stack space as well as context switches.

With mec1322's EMI set to decode IO 0x800, it does not have any other
interfaces to support POST code via IO 0x80.
This change is to enable Port80 POST code support via polling method.
Limitation:
- POST Code 0xFF will be ignored.
- POST Code frequency is greater than 1 msec.
BUG=chrome-os-partner:39386
TEST=Verified Port80 POST code is captured in EC console.
Verified "port80 task" console command will disable/enable Port80 task.
Verified "port80 poll" will get the last Port80 POST code.

- Add a special port80 event for LPC reset assertion and use that event
to store the previous post code.
- Add a new command to retrive the last saved post code so I can easily
query it at boot/resume and log unusual codes.
BUG=none
TEST=manual (with additional coreboot/mosys changes)
- interrupt boot process by issuing x86reset on EC console or
by using warm reset button on servo
- read event log with mosys on next boot

- '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

We can clear the reset cause in system pre-init now because of a
previous change which preserves it across a sysjump.
