Author: ruik Date: 2009-02-19 09:39:16 +0100 (Thu, 19 Feb 2009) New Revision: 3955
Removed: trunk/coreboot-v2/src/mainboard/amd/dbm690t/acpi/cpstate.asl trunk/coreboot-v2/src/mainboard/amd/pistachio/acpi/cpstate.asl Modified: trunk/coreboot-v2/src/mainboard/amd/dbm690t/acpi/dsdt.asl trunk/coreboot-v2/src/mainboard/amd/dbm690t/acpi_tables.c trunk/coreboot-v2/src/mainboard/amd/pistachio/acpi/dsdt.asl trunk/coreboot-v2/src/mainboard/amd/pistachio/acpi_tables.c Log: This patch is for AMD boards which can do the P state generation. This just removes the ugly binary DSDT patching and all other related stuff. Stick to infrastructure in previous patch.
