ChangeLog:
Add initial ACPI support for M57SLI. Activates/Enables: * native Coreboot ACPI for M57SLI * Soft-Power-Off * PowerNow! * High Precision Event Timer * Windows booting with ACPI support Signed-off-by: Harald Gutmann <harald.gutmann@gmx.net> Acked-by: Myles Watson <mylesgw@gmail.com> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4364 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
