From 81f560498bf1ca2bfa738741f63f9bc90a4db7d2 Mon Sep 17 00:00:00 2001 From: Jeff Fan Date: Tue, 19 Jul 2016 08:41:57 +0800 Subject: [PATCH] UefiCpuPkg/MtrrLib: Add notes for usage by BSP/APs Except for MtrrSetAllMtrrs(), others services are not suggested to be invoked by APs because they are not necessary and may invoke DEBUG() to dump MTRR setting.
