When combining UEFI firmware built from Tianocore with ARM Trusted
Firmware running in EL3, it is the responsibility of ATF that only
a single core enters the UEFI firmware in EL2, and the remaining cores
are released directly to the OS via PSCI SMC calls.
In this case, we don't need the MpCore flavor of PrePi or PrePeiCore,
but the UniCore flavor currently checks the CPU identification registers
directly, and refuses to proceed if the boot CPU is part of a MpCore
system.
So drop the ASSERT()'s that implement this check.

The CpuIo2 protocol is required by the generic PciHostBridgeDxe driver,
which relies on it to back its own I/O and MMIO operations.
Since ARM has no native I/O port equivalent, such accesses can only
originate from PCI drivers, and the PCI I/O space is translated to MMIO
in this case.
So we can implement this protocol using MMIO operations only, and take
the PCI I/O translation offset into account when performing I/O port
accesses.

SMM communication buffer is only EfiReservedMemoryType/EfiRuntimeServicesCode/
EfiRuntimeServicesData/EfiACPIMemoryNVS. So that the communication buffer will
not touch any OS memory.
The assumption is that a platform reports valid SMM communication buffer at
EndOfDxe, because EndOfDxe is last hook point that SMM code can call-out to
get memory map information.
A platform MUST finish SMM communication buffer allocation before EndOfDxe.
If a DXE or OS driver need do communication after EndOfDxe, it can either
allocate SMM communication buffer before EndOfDxe and save it, or consume
EDKII_PI_SMM_COMMUNICATION_REGION_TABLE table to get general fixed comm buffer.

OVMF's PlatformBdsLib currently makes SMM vulnerable to the following
attack:
(1) a malicious guest OS copies a UEFI driver module to the EFI system
partition,
(2) the OS adds the driver as a Driver#### option, and references it from
DriverOrder,
(3) at next boot, the BdsEntry() function in
"IntelFrameworkModulePkg/Universal/BdsDxe/BdsEntry.c" processes
Driver#### and DriverOrder between the calls to PlatformBdsInit() and
PlatformBdsPolicyBehavior(),
(4) OVMF locks down SMM only in PlatformBdsPolicyBehavior(), hence the
driver runs with SMM unlocked.
The BdsEntry() function of the MdeModulePkg BDS driver (in file
"MdeModulePkg/Universal/BdsDxe/BdsEntry.c") recommends to "Signal
ReadyToLock event" in PlatformBootManagerBeforeConsole() -- which
corresponds to PlatformBdsInit() --, not in
PlatformBootManagerAfterConsole() -- which corresponds to
PlatformBdsPolicyBehavior().
Albeit an independent question, but it's worth mentioning: this patch also
brings OvmfPkg's PlatformBdsInit() closer to ArmVirtPkg's. Namely, the
latter signals End-of-Dxe in PlatformBdsInit() already.

In the edk2 tree, there are currently four drivers that consume
PcdAcpiS3Enable:
IntelFrameworkModulePkg/Universal/Acpi/AcpiS3SaveDxe/AcpiS3SaveDxe.inf
MdeModulePkg/Universal/Acpi/BootScriptExecutorDxe/BootScriptExecutorDxe.inf
MdeModulePkg/Universal/Acpi/S3SaveStateDxe/S3SaveStateDxe.inf
MdeModulePkg/Universal/Acpi/SmmS3SaveState/SmmS3SaveState.inf
From these, AcpiS3SaveDxe is the only one that isn't also a client of the
S3BootScriptLib class; all the others (BootScriptExecutorDxe,
S3SaveStateDxe, SmmS3SaveState) are clients of the S3BootScriptLib class.
In turn, the edk2 tree contains only one non-Null instance of the
S3BootScriptLib class:
MdeModulePkg/Library/PiDxeS3BootScriptLib/DxeS3BootScriptLib.inf
Therefore we can safely state that BootScriptExecutorDxe, S3SaveStateDxe,
and SmmS3SaveState are all linked against PiDxeS3BootScriptLib.
Now, if PcdAcpiS3Enable is FALSE when either of BootScriptExecutorDxe,
SmmS3SaveState, or SmmS3SaveState is dispatched, then the following
happens:
- The constructor of PiDxeS3BootScriptLib, function
S3BootScriptLibInitialize(), registers a protocol installation callback
for gEfiDxeSmmReadyToLockProtocolGuid. Namely, the function
S3BootScriptEventCallBack().
- The driver immediately exits with EFI_UNSUPPORTED from its entry point
function, upon seeing PcdAcpiS3Enable == FALSE. (See commits
800c02fbe2, 125e093876, and d2d38610603f6.)
- This leaves a dangling callback pointer in the DXE core.
- When Platform BDS installs gEfiDxeSmmReadyToLockProtocolGuid (which is a
valid thing to do for locking down SMM, even in the absence of S3
support!), things blow up.
Fix this issue by returning immediately from S3BootScriptLibInitialize()
if PcdAcpiS3Enable is FALSE -- it is useless to initialize the library
instance if the containing driver module exits first thing in its entry
point.
