Add command for Haswell to pause in s5 at shutdown
At normal AP shutdown, Haswell systems skip S5 entirely and go directly to
G3. It's sometimes handy to pause in S5 as the other systems do, for things
like power-cycle tests that use the RTC to do a delayed wake from S5.
This CL adds a console command and a host command to enable/disable that
pause in S5.
The default is to skip S5, and the override value is not persistent across
EC reboots, so whenever the EC hibernates or reboots (Refresh + Power, software
sync), you'll have to re-enable it again.
BUG=chrome-os-partner:22346
BRANCH=falco,ToT
TEST=manual
On Haswell systems only.
To enable the pause in S5 at shutdown, do either of these:
EC console: gsv s5 1
root shell: ectool pause_in_s5 on
Shut the AP down politely, and it should pause in S5 for 10 seconds before
continuing to G3. You can see this by watching the EC console.
To disable the pause in S5 at shutdown, do any of these:
EC console: gsv s5 0
root shell: ectool pause_in_s5 off
or
press Refresh + POWER
Boot the system, then politely shut down. This time it should go directly to
G3 without pausing in S5.
