port80: Track and export last post code in previous boot
- 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
