When we find that charging is in a wedged state, we may wish to write a
PD log entry, but the PD MCU cannot detect such a state on its own.
Therefore, add a new command to ask the PD MCU to write a log of a given
type, and add a new board-specific custom log event.
BUG=chrome-os-partner:36668
TEST=Manual on samus:
./ectool --dev=1 pdwritelog charge 0
./ectool --dev=1 pdwritelog charge 1
./ectool --dev=1 pdwritelog 1 0
./ectool --dev=1 pdwritelog 2 0
./ectool --dev=1 pdlog
Verify log output matches expectation:
2015-02-12 11:12:49.290 P0 SRC
2015-02-12 11:12:49.296 P1 SNK Charger PD 20286mV max 20000mV / 3000mA
2015-02-12 11:12:49.303 P0 New connection
2015-02-12 11:12:49.310 P0 Board-custom event
--- END OF LOG --
Also, verify kernel logging of wedged event:
[ 181.378420] PDLOG 2015/02/12 19:13:44.019 P0 Event 02 (0000) []
Also, trigger wedged state on Samus and verify log entry is written.
