Add console command to fake battery state of chargetoolchain-3701.42.Bstabilize-3701.81.Bstabilize-3701.46.Bstabilize-3701.30.0bstabilize-3701.30.0release-R26-3701.B
The new 'battfake' command is really handy for testing low-battery
shutdown logic.
BUG=chrome-os-partner:17124
BRANCH=link
TEST=from EC console:
reboot
battfake -> using real battery level
power on system -> lightbar should be blue
battfake 5
lightbar turns red after a few seconds
UI shows battery is very low
(shows <5% due to different kernel math)
'ectool battery' from root shell shows present capacity ~5% of
design capacity
remove AC power
battfake 4
UI shows low-battery screen and shuts down (may take a minute)
battfake 50
power on system
UI shows battery at 45-55%
battfake 2 -> system shuts down immediately
battfake -1
power on system
UI shows actual battery level
