New Revision: 220925
URL: http://svn.freebsd.org/changeset/base/220925
Log:
Add some more bit definitions:
- TCO_MESSAGEx: TCO specific regs providing the ability to monitor BIOS
bootup activity.
- TCO_NEWCENTURY: reporting RTC year roll over.
- TCO_NMI2SMI_EN, TCO_NMI_NOW: controlling SMIs conversion to NMIs and
NMI trigger.
- SMI_GBL_EN: Enabling SMI delivery for all the northbridge controller.
