Subject: [PATCH v4 5/5] UefiCpuPkg/SmmCpuFeaturesLib: Use FixedPCD on non-STM library
Date: Wed,  4 Oct 2017 14:02:27 -0500	[thread overview]
Message-ID: <1507143747-18377-6-git-send-email-leo.duran@amd.com> (raw)
In-Reply-To: <1507143747-18377-1-git-send-email-leo.duran@amd.com>

Consume a FixedPCD to replace Intel-specific macro.
The new PCD will allow SMM support on AMD-based x86 systems.

PcdCpuSmmSmramSaveStateMapOffset - SMRAM Save State Map Offset.
