Public bug reported:
SRU Justification:
[Impact]
The BlueSphere like boards have a feature where the BMC
can trigger a BlueField ARM reset via ipmitool. The ipmitool
command simply toggles the signal on a BMC GPIO pin which
propagates to HOST GPIO 7. HOST GPIO 7 is setup as an
interrupt for SW resetting ARM.
At the moment, the user needs to manually run bfacpievt
script to create acpi files. These files are responsible for
triggering a "reboot". This patch automates this process.
Now, the reboot is entirely handled by the gpio driver.
[Fix]
* Remove the acpi event handler code and replace it with kernel
emergency_restart
[Test Case]
* On BF-2 board with BMC (such as BlueSphere), trigger ARM reset via BMC
ipmitool command.
[Regression Potential]
No known regression.
