Hi David,

Here are my comments:

1. All of the copyright years need to be updated to 2019.
2. Please remove " Contributed-under: TianoCore Contribution Agreement 1.0" from your commit message as it is no longer needed.
3. Please remove interspersed trailing white-space from the following files:

* Platform/Intel/SimicsOpenBoardPkg/AcpiTables/Dsdt.asl
* Platform/Intel/SimicsOpenBoardPkg/AcpiTables/Platform.h
* Platform/Intel/SimicsOpenBoardPkg/Include/Register/X58SmramSaveStateMap.h
* Platform/Intel/SimicsOpenBoardPkg/PlatformPei/Platform.c
* Platform/Intel/SimicsOpenBoardPkg/SimicsOpenBoardPkg.dec

4. Platform/Intel/SimicsOpenBoardPkg/PlatformDxe/Platform.c - Line 2 - " This driver effectuates OVMF's platform..." - This is not OVMF, this is Simics, please update.
5. Platform/Intel/SimicsOpenBoardPkg/SmbiosPlatformDxe/SmbiosPlatformDxe.inf - Line 2 - " This driver installs SMBIOS information for OVMF" - This is not OVMF, this is Simics, please update.

Other than that, looks good! Please send an updated patch.

Thanks,
Nate

+

+ if performing a DMA write operation, the data must not be accessed in system
