From 469f593498cabf0bf205833bab4218e409929cf8 Mon Sep 17 00:00:00 2001 From: Paul Menzel Date: Tue, 13 Oct 2015 21:07:32 +0200 Subject: cpu/intel: Move Power notification ASL code into `common/acpi` Commit 24813c14 (i945: Consolidate acpi/platform.asl) creates the file in the directory `src/cpu/intel/model_6dx/acpi`, although the devices can also use different Intel CPU models like, for example, `intel/model_6ex` on the Lenovo T60. Therefore move the file to the directory `src/cpu/intel/common/acpi` so that other devices, like Intel GM45 based devices, can also include it.
