cr50: check if the new image needs to be enabled and act on it
The AP sends the Cr50 a request to enable the new firmware image. If
the new Cr50 image was found and enabled, the AP expects the Cr50 to
reset the device in 1 second.
While waiting for the Cr50 to reset, the AP logs a newly defined event
and optionally shuts down the system. By default the x86 systems power
off as shutting those systems down is not board specific.
BRANCH=gru,reef
BUG=b:35580805
TEST=built a reef image, observed that in case cr50 image is updated,
after the next reboot the AP stops booting before loading depthcharge,
reports upcoming reset and waits for it.
Once the system is booted after that, the new event can be found
in the log:
localhost ~ # mosys eventlog list
