Add LastRebootCause property for BMC Reboot Cause feature
Scenario:
Customer want to know the last reboot cause of BMC through OpenBMC WebUI.
Thus, we need to add LastRebootCause property in BMC.interface.yaml.
Meanwhile, we also modify phosphor-state-manager and phosphor-webui
to support show BMC Reboot Cause information in Reboot BMC page.
Tested:
busctl get-property xyz.openbmc_project.State.BMC /xyz/openbmc_project/state/bmc0 xyz.openbmc_project.State.BMC LastRebootCause
When unplug/plug in BMC power cable then return as below: (POR i.e. Power-On-Reset)
s "xyz.openbmc_project.State.BMC.BMCResetCause.POR"
When executing reboot command then return as below:
s "xyz.openbmc_project.State.BMC.BMCResetCause.Watchdog"
