Scanning for PCI Option ROMs on UEFI works with full PCI enumeration.
On platforms where the bootloader has done PCI enumeration a
platform specific driver needs to provide the Option ROMs.
As this is not specific to any platform, but rather to the UEFI as
payload concept, add the PCI platform driver to UefiPayloadPkg.
On coreboot the ROM BAR is part of the PCI bridge MMIO window and
can safely enabled if existing.
The Option ROMs are not passed in by bootloader in a HOB as:
- they might not fit into a HOB
- this is EDK2 specific and would just bloat the bootloader code
- would waste lot's of non reclaimable memory if placed in e820
reserved DRAM space

BMP files by tools other than MS paint can have a
variable number of padding bytes, which results in
the DataSize being less than (ImageSize - HeaderSize).
Fix the check to be less stringent.
Test: use BMP created by/saved by Photoshop

This is a shoehorned-in implementation of an ACPI BGRT
table, ported pretty much directly from the version used
under CorebootPayloadPkg.
EDK2 provides a facility to do this already, but it assumes
the ACPI tables already exist as EFI structures, so would need
to write code to populate those using the tables already in RAM
created by coreboot. This seemed like the easier option ATM.

kvm FSB clock is 1GHz, not 100 MHz. Timings are off by factor 10.
Fix all affected build configurations. Not changed: Microvm and
Cloudhw (they have already have the correct value), and Xen (has
no fixed frequency, the PCD is configured at runtime by platform
initialization code).

In TDX, Application Processor busy-loops on Mailbox for OS to issue
MpProtectedModeWakeupCommandWakeup command to UEFI. As the AP acking to
it, it clears the command member according to ACPI spec 6.4, 5.2.12.19
Multiprocessor Wakeup Structure: "The application processor need clear the
command to Noop(0) as the acknowledgement that the command is received."
However, AsmRelocateApMailBoxLoop wrongly clears WakeupVector. Correctly
clear command instead of WakeupVector.
Without this patch, TD guest kernel fails to boot APs.

The BaseMemEncryptSevLib functionality was updated to rely on the use of
the OVMF/SEV workarea to check for SEV guests. However, this area is only
updated when running the X64 OVMF build, not the hybrid Ia32/X64 build.
Base SEV support is allowed under the Ia32/X64 build, but it now fails
to boot as a result of the change.
Update the ResetVector code to check for SEV features when built for
32-bit mode, not just 64-bit mode (requiring updates to both the Ia32
and Ia32X64 fdf files).

Adds a new library class VariableFlashInfoLib that abstracts access
to variable flash information. The instance provided first attempts
to retrieve information from the Variable Flash Info HOB. If that
HOB is not present, it falls back to the PCDs defined in
MdeModulePkg.
This fall back behavior provides backward compatibility for platforms
that only provide PCDs but also allows platforms that need to
dynamically provide the information using the Variable Flash Info HOB
to do so at runtime.

Adds a new GUID that is used to identify a HOB that passes variable
flash information to UEFI variable drivers in HOB consumption phases
such as DXE, Traditional MM, and Standalone MM.
This information was previously passed directly with PCDs such
as EfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableBase
and gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableSize.
However, the Standalone MM variable driver instance does not have
direct access to the PCD database. Therefore, this HOB will first
be considered as the source for variable flash information and
if platforms do not produce the HOB, reading the information from
the PCDs directly will be a backup to provide backward
compatibility.
