Min Xu 4b0a622635 OvmfPkg/IntelTdx: Measure Td HobList and Configuration FV
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3853

TdHobList and Configuration FV are external data provided by Host VMM.
These are not trusted in Td guest. So they should be validated , measured
and extended to Td RTMR registers. In the meantime 2 EFI_CC_EVENT_HOB are
created. These 2 GUIDed HOBs carry the hash value of TdHobList and
Configuration FV. In DXE phase EFI_CC_EVENT can be created based on these
2 GUIDed HOBs.

Min Xu a708536dce OvmfPkg: Introduce SecMeasurementLib
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3853

SecMeasurementLib is designed to do the measurement in SEC phase. In
current stage there are 2 functions introduced:
 - MeasureHobList: Measure the Hoblist passed from the VMM.
 - MeasureFvImage: Measure the FV image.

SecMeasurementLibTdx is the TDX version of the library.

Sebastien Boeuf bf25f27e00 OvmfPkg: Don't access A20 gate register on Cloud Hypervisor
Since Cloud Hypervisor doesn't emulate an A20 gate register on I/O port
0x92, it's better to avoid accessing it when the platform is identified

Sebastien Boeuf 3129ed374c OvmfPkg: CloudHv: Rely on QemuFwCfgLibNull implementation
Since Cloud Hypervisor doesn't support the fw_cfg mechanism, it's more
appropriate to rely on QemuFwCfgLibNull implementation of QemuFwCfgLib
since it provides a null implementation that will not issue any PIO
accesses to ports 0x510 and 0x511.

Sebastien Boeuf 5c9f151e0c OvmfPkg: CloudHv: Fix FW_BASE_ADDRESS
The FW_BASE_ADDRESS value provided by OvmfPkgDefines.fdf.inc is
incorrect for the CloudHv target. We know the generated firmware
contains a PVH ELF header, meaning it will be loaded according to the
address provided through this header. And since we know this address
isn't going to change as it's part of CloudHvElfHeader.fdf.inc, we can
hardcode it through a new include file CloudHvDefines.fdf.inc, which
replaces the generic one OvmfPkgDefines.fdf.inc.

With this change, we prevent the firmware from accessing MMIO addresses
from the address range 0xffc00000-0xffffffff since we know the firmware
hasn't been loaded on this address range.

Gerd Hoffmann bd10d4e201 OvmfPkg/Microvm/pcie: mPhysMemAddressWidth tweak
microvm places the 64bit mmio space at the end of the physical address
space.  So mPhysMemAddressWidth must be correct, otherwise the pci host
bridge setup throws an error because it thinks the 64bit mmio window is
not addressable.

On microvm we can simply use standard cpuid to figure the address width
because the host-phys-bits option (-cpu ${name},host-phys-bits=on) is
forced to be enabled.  Side note: For 'pc' and 'q35' this is not the
case for backward compatibility reasons.

Min Xu 64706ef761 OvmfPkg: Search EFI_RESOURCE_MEMORY_UNACCEPTED for Fw hoblist
In current TDVF implementation all unaccepted memory passed in Hoblist
are tagged as EFI_RESOURCE_MEMORY_UNACCEPTED. They're all accepted before
they can be accessed. After accepting memory region, the Hob ResourceType
is unchanged (still be EFI_RESOURCE_MEMORY_UNACCEPTED).

TDVF Config-B skip PEI phase and it tries to find a memory region which
is the largest one below 4GB. Then this memory region will be used as the
firmware hoblist.

So we should walk thru the input hoblist and search for the memory region
with the type of EFI_RESOURCE_MEMORY_UNACCEPTED.

Because EFI_RESOURCE_MEMORY_UNACCEPTED has not been officially in PI spec.
So it cannot be defined in MdePkg/Include/Pi/PiHob.h. As a temporary
solution it is defined in Hob.c.

There is a patch-set for lazy-accept very soon. In that patch-set
EFI_RESOURCE_MEMORY_UNACCEPTED will be defined in MdeModulePkg.

the SEV_STATUS MSR Bit 1 to determine if SEV-ES is enabled. This check
was not part of the original SEV-ES support and was added in

Min Xu a72d552f19 OvmfPkg/OvmfPkgX64: Use different CcProbeLib when SMM is on or off
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3930

CcProbeLib is designed to check the vm guest type. The OvmfPkg/CcProbeLib
reads the OvmfWorkArea (0x80B000) to get the vm guest type which is
written by each guest (SEV or TDX guest). But in SMM drivers the access
to OvmfWorkArea is illegal. PiSmmCpuDxeSmm.inf is an example. It uses
IoLib which in OvmfPkgX64 BaseIoLibIntrinsicSev.inf is included. The
IoLib probes if the working guest is td guest by calling CcProbe().

So CcProbeLibNull will be included when SMM_REQUIRE is set. Currently
only TDVF uses CcProbe to check the guest type, and TDVF doesn't
support SMM, so this fix has no side-effect.

QemuFwCfg is much more powerful than BhyveFwCtl. Sadly, BhyveFwCtl
decided to use the same IO ports as QemuFwCfg. It's not possible to use
both interfaces simultaneously. So, prefer QemuFwCfg over BhyveFwCtl.

Min Xu 892787fed5 OvmfPkg/OvmfPkgX64: Adjust load sequence of TdxDxe and AmdSevDxe driver
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3904

TdxDxe driver is introduced for Intel TDX feature. Unfortunately, this
driver also breaks boot process in SEV-ES guest. The root cause is in
the PciLib which is imported by TdxDxe driver.

In a SEV-ES guest the AmdSevDxe driver performs a
MemEncryptSevClearMmioPageEncMask() call against the
PcdPciExpressBaseAddress range to mark it shared/unencrypted. However,
the TdxDxe driver is loaded before the AmdSevDxe driver, and the PciLib
in TdxDxe is DxePciLibI440FxQ35 which will access the
PcdPciExpressBaseAddress range. Since the range has not been marked
shared/unencrypted, the #VC handler terminates the guest for trying to
do MMIO to an encrypted region.

Adjusting the load sequence of TdxDxe and AmdSevDxe can fix the issue.

Are auto generated by the following generators:
  OvmfPkg/Bhyve/BhyveRfbDxe/VbeShim.sh
  OvmfPkg/QemuVideoDxe/VbeShim.sh

Therefore, Uncrustify causes a file update to produce a very large
diff due to formatting changes.

This change does the following:
  1. Reverts the Uncrustify changes applied to the files in commit
     ac0a286f4d.
  2. Uses a new UncrustifyCheck CI plugin configuration option to
     exclude the files from future formatting checks.

Min Xu 44a53a3bdd OvmfPkg: Introduce IntelTdxX64 for TDVF Config-B
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

Intel's Trust Domain Extensions (Intel TDX) refers to an Intel technology
that extends Virtual Machines Extensions (VMX) and Multi-Key Total Memory
Encryption (MKTME) with a new kind of virutal machines guest called a
Trust Domain (TD). A TD is desinged to run in a CPU mode that protects the
confidentiality of TD memory contents and the TD's CPU state from other
software, including the hosting Virtual-Machine Monitor (VMM), unless
explicitly shared by the TD itself.

There are 2 configurations for TDVF to upstream. See below link for
the definitions of the 2 configurations.
https://edk2.groups.io/g/devel/message/76367

This patch-set is to enable the basic feature of Config-B in OvmfPkg.
 - Add a standalone IntelTdxX64.dsc to a TDX specific directory for a
   *full* feature TDVF. (Align with existing SEV)
 - IntelTdx.dsc includes Tdx/Legacy OVMF basic boot capability. The
   final binary can run on Tdx/Legacy OVMF.
 - PEI phase is skipped.

By design in Config-B there should be more advanced features, such as:
 - RTMR based measurement and measure boot.
 - Remove unnecessary drivers to reduce attack surface, such as
   network stack.

To make the code review more efficiency, Config-B is split into 2 waves:
 - Basic feature of Config-B
 - Advanced feature of Config-B

This patch contains 2 files (IntelTdxX64.dsc/IntelTdxX64.fdf) which
enable the basic feature of Config-B. In the waves of Advanced feature
of Config-B, we will re-visit these 2 files.

TDX_PEI_LESS_BOOT is defined in IntelTdxX64.dsc to indicate it boots up
without PEI phase.

is skipped so that the attack surfaces are reduced as much as possible.

PeilessStartup() does below tasks:
1. Contruct the FW hoblist.
   Since PEI is skipped, we must find a memory region which is the
   largest one below 4GB. Then this memory region will be used as the
   firmware hoblist.
2. Initialize the platform.
3. Build various Hobs, such as SecFv Hob, DxeFv Hob, Stack Hob, etc.
4. At last DXE Core is located / loaded and transfer control to it.

Discussion in https://bugzilla.tianocore.org/show_bug.cgi?id=1496 shows
that 8254TimerDxe was not written for OVMF. It was moved over from
PcAtChipsetPkg to OvmfPkg in 2019.  Probably because OVMF was the only
user left.

Most likely the reason OVMF used 8254TimerDxe initially was that it could
just use the existing driver in PcAtChipsetPkg.  And it simply hasn't
been changed ever.

CSM support was moved in 2019 too. (CSM support depends on 8254/8259
drivers). So 8254TimerDxe will be used when CSM_ENABLE=TRUE.

There are 4 .dsc which include the 8254Timer.
 - OvmfPkg/AmdSev/AmdSevX64.dsc
 - OvmfPkg/OvmfPkgIa32.dsc
 - OvmfPkg/OvmfPkgIa32X64.dsc
 - OvmfPkg/OvmfPkgX64.dsc

For the three OvmfPkg* configs using 8254TimerDxe with CSM_ENABLE=TRUE
and LapicTimerDxe otherwise.

For the AmdSev config it doesn't make sense to support a CSM. So use
the lapic timer unconditionally.

Min Xu 2520182122 OvmfPkg: Update IoMmuDxe to support TDX
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

The IOMMU protocol driver provides capabilities to set a DMA access
attribute and methods to allocate, free, map and unmap the DMA memory
for the PCI Bus devices.

The current IoMmuDxe driver supports DMA operations inside SEV guest.
To support DMA operation in TDX guest,
CC_GUEST_IS_XXX (PcdConfidentialComputingGuestAttr) is used to determine
if it is SEV guest or TDX guest.

Due to security reasons all DMA operations inside the SEV/TDX guest must
be performed on shared pages. The IOMMU protocol driver for the SEV/TDX
guest uses a bounce buffer to map guest DMA buffer to shared pages in
order to provide the support for DMA operations inside SEV/TDX guest.

The call of SEV or TDX specific function to set/clear EncMask/SharedBit
is determined by CC_GUEST_IS_XXX (PcdConfidentialComputingGuestAttr).

Min Xu fae5c1464d OvmfPkg: Add TdxDxe driver
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

TdxDxe driver is dispatched early in DXE, due to being list in APRIORI.
This module is responsible for below features:
 - Sets max logical cpus based on TDINFO
 - Sets PCI PCDs based on resource hobs
 - Set shared bit in MMIO region
 - Relocate Td mailbox and set its address in MADT table.

1. Set shared bit in MMIO region

Qemu allows a ROM device to set to ROMD mode (default) or MMIO mode.
When it is in ROMD mode, the device is mapped to guest memory and
satisfies read access directly.

In EDK2 Option ROM is treated as MMIO region. So Tdx guest access
Option ROM via TDVMCALL(MMIO). But as explained above, since Qemu set
the Option ROM to ROMD mode, the call of TDVMCALL(MMIO) always return
INVALID_OPERAND. Tdvf then falls back to direct access. This requires
to set the shared bit to corresponding PageTable entry. Otherwise it
triggers GP fault.

TdxDxe's entry point is the right place to set the shared bit in MMIO
region because Option ROM has not been discoverd yet.

2. Relocate Td mailbox and set the new address in MADT Mutiprocessor
Wakeup Table.

In TDX the guest firmware is designed to publish a multiprocessor-wakeup
structure to let the guest-bootstrap processor wake up guest-application
processors with a mailbox. The mailbox is memory that the guest firmware
can reserve so each guest virtual processor can have the guest OS send
a message to them. The address of the mailbox is recorded in the MADT
table. See [ACPI].

TdxDxe registers for protocol notification
(gQemuAcpiTableNotifyProtocolGuid) to call the AlterAcpiTable(), in
which MADT table is altered by the above Mailbox address. The protocol
will be installed in AcpiPlatformDxe when the MADT table provided by
Qemu is ready. This is to maintain the simplicity of the AcpiPlatformDxe.

AlterAcpiTable is the registered function which traverses the ACPI
table list to find the original MADT from Qemu. After the new MADT is
configured and installed, the original one will be uninstalled.

-  query whether TDX is enabled.

Please be noted, there a lot of duplicated codes for Page Table

(PageTablesLib) so that it is more friendly for review and maintain.
There is a new feature requirement
https://bugzilla.tianocore.org/show_bug.cgi?id=847 which is to

Min Xu e23f8f52fd OvmfPkg: Update PlatformInitLib for Tdx guest
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

There are below changes in PlatformInitLib for Tdx guest:

1. Publish ram regions
In Tdx guest, the system memory is passed in TdHob by host VMM. So
the major task of PlatformTdxPublishRamRegions is to walk thru the
TdHob list and transfer the ResourceDescriptorHob and MemoryAllocationHob
to the hobs in DXE phase.

2. Build MemoryAllocationHob for Tdx Mailbox and Ovmf work area.

3. Update of PlatformAddressWidthInitialization. The physical
address width that Tdx guest supports is either 48 or 52.

4. Update of PlatformMemMapInitialization.
0xA0000 - 0xFFFFF is VGA bios region.  Platform initialization marks the
region as MMIO region. Dxe code maps MMIO region as IO region.
As TDX guest, MMIO region is maps as shared.  However VGA BIOS doesn't need
to be shared.  Guest TDX Linux maps VGA BIOS as private and accesses for
BIOS and stuck on repeating EPT violation.  VGA BIOS (more generally ROM
region) should be private.  Skip marking VGA BIOA region [0xa000, 0xfffff]
as MMIO in HOB.

Min Xu 2b80269d98 OvmfPkg: Update Sec to support Tdx
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

There are below major changes in this commit.

1. SecEntry.nasm
In TDX BSP and APs goes to the same entry point in SecEntry.nasm.

BSP initialize the temporary stack and then jumps to SecMain, just as
legacy Ovmf does.

APs spin in a modified mailbox loop using initial mailbox structure.
Its structure defition is in OvmfPkg/Include/IndustryStandard/IntelTdx.h.
APs wait for command to see if the command is for me. If so execute the
command.

2. Sec/SecMain.c
When host VMM create the Td guest, the system memory informations are
stored in TdHob, which is a memory region described in Tdx metadata.
The system memory region in TdHob should be accepted before it can be
accessed. So the major task of this patch is to process the TdHobList
to accept the memory. After that TDVF follow the standard OVMF flow
and jump to PEI phase.

PcdUse1GPageTable is set to FALSE by default in OvmfPkgX64.dsc. It gives
no chance for Intel TDX to support 1G page table. To support 1G page
table this PCD is set to TRUE in OvmfPkgX64.dsc.

TDX_GUEST_SUPPORTED is defined in OvmfPkgX64.dsc. This macro wraps the
Tdx specific code.

TDX only works on X64, so the code is only valid in X64 arch.

Min Xu b22ac35b75 OvmfPkg: Update PlatformInitLib to process Tdx hoblist
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

When host VMM create the Td guest, the system memory informations are
stored in TdHob, which is a memory region described in Tdx metadata.
The system memory region in TdHob should be accepted before it can be
accessed. So the newly added function (ProcessTdxHobList) is to process
the TdHobList to accept the memory. Because TdHobList is provided by
host VMM which is not trusted, so its content should be checked before
it is consumed by TDVF.

Because ProcessTdxHobList is to be called in SEC phase, so
PlatformInitLib.inf is updated to support SEC.

Note: In this patch it is BSP which accepts the pages. So there maybe
boot performance issue. There are some mitigations to this issue, such
as lazy accept, 2M accept page size, etc. We will re-visit here in the
future.

EFI_RESOURCE_MEMORY_UNACCEPTED is a new ResourceType in
EFI_HOB_RESOURCE_DESCRIPTOR. It is defined for the unaccepted memory
passed from Host VMM. This is proposed in microsoft/mu_basecore#66
files#diff-b20a11152d1ce9249c691be5690b4baf52069efadf2e2546cdd2eb663d80c9
e4R237 according to UEFI-Code-First. The proposal was approved in 2021
in UEFI Mantis, and will be added to the new PI.next specification.

Per the MdePkg reviewer's comments, before this new ResourceType is
added in the PI spec, it should not be in MdePkg. So it is now
defined as an internal implementation and will be moved to
MdePkg/Include/Pi/PiHob.h after it is added in PI spec.
See https://edk2.groups.io/g/devel/message/87641

PcdTdxAcceptPageSize is added for page accepting. Currently TDX supports
4K and 2M accept page size. The default value is 2M.

Tdx guest is only supported in X64. So for IA32 ProcessTdxHobList
just returns EFI_UNSUPPORTED.

In MiscInitialization Microvm looks a little weird. Other platforms
call PcdSet16S to set the PcdOvmfHostBridgePciDevId with the value same
as PlatformInfoHob->HostBridgeDevId. But Microvm doesn't follow this
way. In switch-case 0xffff is Microvm, but set with
MICROVM_PSEUDO_DEVICE_ID. So we have to add a new function
( MiscInitializationForMicrovm ) for Microvm and delete the code in
MiscInitialization.

Min Xu 9a9b33b3d6 OvmfPkg/PlatformPei: Move global variables to PlatformInfoHob
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3863

The intention of PlatformInitLib is to extract the common function used
in OvmfPkg/PlatformPei. This lib will be used not only in PEI phase but
also in SEC phase. SEC phase cannot use global variables between
different functions. So PlatformInfoHob is created to hold the
informations shared between functions. For example, HostBridgeDevId
corespond to mHostBridgeDevId in PlatformPei.

In this patch we will first move below global variables to
PlatformInfoHob.
 - mBootMode
 - mS3Supported
 - mPhysMemAddressWidth
 - mMaxCpuCount
 - mHostBridgeDevId
 - mQ35SmramAtDefaultSmbase
 - mQemuUc32Base
 - mS3AcpiReservedMemorySize
 - mS3AcpiReservedMemoryBase

PlatformInfoHob also holds other information, for example,
PciIoBase / PciIoSize. This is because in SEC phase, PcdSetxxx
doesn't work. So we will restruct the functions which set PCDs
into two, one for PlatformInfoLib, one for PlatformPei.

So in this patch we first move global variables and PCDs to
PlatformInfoHob. All the changes are in OvmfPkg/PlatformPei.

 - PlatformAddIoMemoryRangeHob
 - PlatformAddMemoryBaseSizeHob
 - PlatformAddMemoryRangeHob
 - PlatformAddReservedMemoryBaseSizeHob

They correspond the below functions in OvmfPkg/PlatformPei:

 - AddIoMemoryRangeHob
 - AddMemoryBaseSizeHob
 - AddMemoryRangeHob
 - AddReservedMemoryBaseSizeHob

After above hob functions are introduced in PlatformInitLib,
OvmfPkg/PlatformPei is refactored with this library.

Min Xu 57bcfc3b06 OvmfPkg: Create initial version of PlatformInitLib
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3863

There are 3 variants of PlatformPei in OvmfPkg:
 - OvmfPkg/PlatformPei
 - OvmfPkg/XenPlatformPei
 - OvmfPkg/Bhyve/PlatformPei/PlatformPei.inf
These PlatformPeis can share many common codes, such as
Cmos / Hob / Memory / Platform related functions. This commit
(and its following several patches) are to create a PlatformInitLib
which wraps the common code called in above PlatformPeis.

In this initial version of PlatformInitLib, below Cmos related functions
are introduced:
 - PlatformCmosRead8
 - PlatformCmosWrite8
 - PlatformDebugDumpCmos

They correspond to the functions in OvmfPkg/PlatformPei:
 - CmosRead8
 - CmosWrite8
 - DebugDumpCmos

Considering this PlatformInitLib will be used in SEC phase, global
variables and dynamic PCDs are avoided. We use PlatformInfoHob
to exchange information between functions.

EFI_HOB_PLATFORM_INFO is the data struct which contains the platform
information, such as HostBridgeDevId, BootMode, S3Supported,
SmmSmramRequire, etc.

After PlatformInitLib is created, OvmfPkg/PlatformPei is refactored
with this library.

Brijesh Singh c28e376edc OvmfPkg/FvbServicesSmm: use the VmgExitLibNull
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3835

The commit ade62c18f4 caused a boot failure
when OVMF is build with SECURE_BOOT/SMM enabled.

This happen because the above commit extended the BaseMemEncryptSevLib.inf
to include VmgExitLib. The FvbServicesSmm uses the functions provided
by the MemEncryptSevLib to clear the memory encryption mask from the
page table. It created a dependency, as shown below

OvmfPkg/FvbServicesSmm.inf
 ---> MemEncryptSevLib                   class
 ---> "OvmfPkg/BaseMemEncryptSevLib/DxeMemEncryptSevLib.inf"  instance
 ---> VmgExitLib
 ---> "OvmfPkg/VmgExitLib"    instance
 ---> LocalApicLib                       class
 ---> UefiCpuPkg/BaseXApicX2ApicLib/BaseXApicX2ApicLib.inf    instance
 ---> TimerLib                           class
 ---> "OvmfPkg/AcpiTimerLib/DxeAcpiTimerLib.inf"              instance
 ---> PciLib                             class
 ---> "OvmfPkg/DxePciLibI440FxQ35/DxePciLibI440FxQ35.inf"     instance

The LocalApicLib provides a constructor, execution of the constructor
causes an exception. The SEV-ES and SEV-SNP do not support the SMM, so
skip including the VmgExitLib chain. Use the module override to use the
VmgExitLibNull to avoid the inclusion of unneeded LocalApicLib dependency
chain in FvbServicesSmm. We ran similar issue for AmdSevDxe driver,
see commit 19914edc5a

After the patch, the dependency look like this:

OvmfPkg/FvbServicesSmm.inf
 ---> MemEncryptSevLib                   class
 ---> "OvmfPkg/BaseMemEncryptSevLib/DxeMemEncryptSevLib.inf"  instance
 ---> VmgExitLib
 ---> "UefiCpuPkg/Library/VmgExitLibNull"    instance

Also add the resolution to the mode list.

This will make OVMF boot up with the display resolution configured by
QEMU, which is 1280x800 by default.  The resolution can be set using the
xres and yres properties.  Here is an example for FullHD:

Gerd Hoffmann 929804b172 OvmfPkg: add PcdVideoResolutionSource
It's a UINT8 (enum) PCD telling where the PcdVideoHorizontalResolution
and PcdVideoVerticalResolution values are coming from.  It can be:

 0 (unset aka default from dsc file), or
 1 (from PlatformConfig), or
 2 (set by Video Driver).

It will be used by video drivers to avoid overriding PlatformConfig
values, or override each others values in case multiple display devices
are present.

The underlying problem this tries to solve is that the GOP protocol has
no way to indicate the preferred video mode.  On physical hardware this
isn't much of a problem because using the highest resolution available
works just fine as that is typically the native display resolution

But in a virtual machine you don't want come up with a huge 4k window by
default just because the virtual vga is able to handle that.  Cutting
down the video mode list isn't a great solution either as that would
also remove the modes from the platform configuration so the user
wouldn't be able to pick a resolution higher than the default any more.

So with patch drivers can use use PcdVideoHorizontalResolution and
PcdVideoVerticalResolution to indicate what the preferred display
resolution is, without overwriting the user preferences from
PlatformConfig if present.

A possible alternative approach would be to extend the GOP protocol, but
I'm not sure this is a good plan given this is mostly a problem for
virtual machines and using PCDs allows to keep this local to OvmfPkg.

FdtClient is unhappy without a device tree, so add an empty fdt

On ARM machines a device tree is mandatory for hardware detection,
that's why FdtClient fails hard.

On microvm the device tree is only used to detect virtio-mmio devices
(this patch series) and the pcie host (future series).  So edk2 can
continue with limited functionality in case no device tree is present:
no storage, no network, but serial console and direct kernel boot
works.

Move SettingsManager and PlatformBuilder classes to PlatformBuildLib.py
file, keep only CommonPlatform class in PlatformBuild.py.  Allows
reusing these classes for other builds.  Pure code motion, no functional
change.

lixianglai 2b20a34fd5 OvmfPkg-EmuVariableFvbRuntimeDxe: Support Access To Memory Above 4G
In FvbInitialize Function,
PcdFlashNvStorageVariableBase64 PcdFlashNvStorageFtwWorkingBase
PcdFlashNvStorageFtwSpareBase will not exceed 0x100000000,
Due to truncation and variable type limitations.
That leads to the NV variable cannot be saved to the memory above 4G.

Modify as follows:
1.Remove the forced type conversion of UINT32.
2.Use UINT64 type variables.

Jason Andryuk f6df289a1c OvmfPkg/OvmfXen: Fix Xen build
commit 202fb22be6 "OvmfPkg/SecMain: validate the memory used for
decompressing Fv" broke building OvmfXen with:

edk2/OvmfPkg/OvmfXen.dsc(...): error 1001: Module type [SEC] is not
supported by library instancer
[edk2/OvmfPkg/Library/BaseMemEncryptSevLib/DxeMemEncryptSevLib.inf]
	consumed by [edk2/OvmfPkg/Sec/SecMain.inf]

The above commit added a reference to MemEncryptSevLib into SecMain.inf,
but OvmfXen.dsc doesn't have a MemEncryptSevLib entry for SEC.  Add one
like OvmfPkgX64.dsc has.

Don't make the package Qemu centric so that we can introduce some
alternative support for other VMMs not using the fw_cfg mechanism.

This patch is purely about renaming existing files with no functional
change.
