IPMI: Introduce attention call
Presently abort() function is not working on BMC based machine. System
hangs after abort/assert call. We have to reboot machine from BMC (IPMI
command or BMC console).
This patch introduces attention functionality for BMC based machine.
It logs eSEL event that contains OPAL version, file info and backtrace.
And calls cec_reboot... which takes care of rebooting host.
Note:
- This patch uses ipmi_queue_msg() instead of ipmi_queue_msg_sync() as
we are having some issues with sync path. This will resolved once we
sort out [1].
- This patch calls cec_reboot to reboot machine after logging eSEL event.
It queues IPMI message and bt_poll() should be working until we pass
reboot IPMI message to BMC. Hence we have while loop with time_wait_ms().
Alternatively we can use xscom_trigger_xstop().. but it will stop
immediately and eSEL logging fails.
