Subject: ipmi: raise precedence of PNP based discovery mechanisms (ACPI, PCI)
From: Myron Stowe <myron.stowe@xxxxxx>
This raises the precedence of PNP discovery mechanisms, ACPI and PCI,
above SMBIOS and SPMI as indicated by Appendix C1 of the IPMI
specification.
Reference: IPMI - Intelligent Platform Management Interface Specification
v2.0, Document Revision 1.0, 05.05.2005 Markup
Appendix C1 - Locating IPMI System Interfaces via SMBIOS Tables
"Note that the settings that this structure reports may be over-
ridden by `Plug-and-Play' reassignment by the OS. Therefore, this
structure should be used only when the interface cannot be
discovered via `Plug-and-Play' discovery mechanisms incorporated
in interfaces such as PCI and ACPI."
