From 585a4006976e903599b7128200a29b5729777818 Mon Sep 17 00:00:00 2001 From: zbao Date: Thu, 12 Apr 2012 11:27:26 +0800 Subject: Leverage the Pstate table created by AGESA. The name of processor created by AGESA is P00n, whose P is BLDCFG_PROCESSOR_SCOPE_NAME(is 'C' if it is undefined.) and n starts from 0. The dsdt should be aligned with that. This feature has only been tested on persimmon. The changes on all the other boards were propagated.
