Subject: [PATCH v4 1/5] UefiCpuPkg/UefiCpuPkg.dec: Create FixedPCDs for SMM support
Date: Wed,  4 Oct 2017 14:02:23 -0500	[thread overview]
Message-ID: <1507143747-18377-2-git-send-email-leo.duran@amd.com> (raw)
In-Reply-To: <1507143747-18377-1-git-send-email-leo.duran@amd.com>

Introduce a couple of FixedPCDs to replace Intel-specific macros.
The new PCDs will allow SMM support on AMD-based x86 systems.

1) PcdCpuSmmSmramSaveStateMapOffset - SMRAM Save State Map Offset.
2) PcdCpuSmmPSDOffset - Processor SMM Descriptor Offset in SMRAM.
