- '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
