From: Zhao Yakui <yakui.zhao@xxxxxxxxx> Sometimes one IPMI system interface will be detected by several methods. For example: ACPI mechanism, SPMI table, DMI. In such case when one IPMI system interface can be detected in two mechanism, the second mechanism will fail in the detection and can't record which IPMI system interface is detected by it. Use the ACPI detection mechanism firstly to detect the IPMI system interface so that we can know which IPMI system interface is detected in ACPI namespace and then install the IPMI opregion to enable ACPI to access the BMC controller. But the hardcode detection mechanism is still put in the first order.
