In platform which support ACPI 2.0 only, the base address of ACPI region
is not page aligned. This unalinged base address leads to failure at
BuildMemoryAllocationHob when parsing ACPI node in FdtParserLib, before
building gUniversalPayloadAcpiTableGuid GUID HOB.
Align base address of ACPI region down to EFI_PAGE_SIZE to make sure
base address always aligned.

PixelsPerScanLine is required in some UEFI capable OS distribution.
To align with simple-framebuffer definition in kernel Documentation:
devicetree/bindings/display/simple-framebuffer.txt, no property node
will be introduced for PixelsPerScanLine.
Set value of PixelsPerScanLine to HorizontalResolution, as they are
identical in most cases.

Current implementation only supports serial port sub-node under
PCI root bridge node.
This enhancement support serial port node regardless it is under
root node or PCI root bridge node using a single FDT passing function.

If alignment check is enabled in AARCH64 platform, FDT parser might
dereference non-aligned 64-bit address to fetch 64-bit data.
Use unaligned data read to avoid triggering unaligned data access.

Per other platform request , need to add SMBIOS device node into FDT.
In the current phase(1) , only supporting SM3EntryPoint structure.

FdtNumRsv and FdtGetMemRsv were added for the benefit of UefiPayloadPkg,
but their naming matches neither upstream libfdt nor tianocore coding
style rules. And there was scope for improvement of the doxygen
descriptions as well.
These functions currently have only one in-tree user, UefiPayloadPkg
FdtParserLib. So rename them more conformant
FdtGetNumberOfReserveMapEntries
and
FdtGetReserveMapEntry
and update the description comment blocks, at the same time as
updating the existing user.

DT has a way to provide reserved images in a simpler tabular
manner. UPL should be able to support that.

In order to properly enable multisegment RB, we need
to grab ecam data from the FDT for each bridge.
Current UNIVERSAL_PAYLOAD_PCI_ROOT_BRIDGES struct from
MdeModulePkg does not include definition for ecam. In
order to maintain backward compatibility and also avoid
diverging too much from core, we are going to define a
new HOB for UPL segment information and pass it to
GetPciSegmentInfo function. Ths function then grabs specifically
ecam info from the segment hob along with other rb specific
information to create final RB info required by multi segment
PCI driver.
Additionally we would like to support legacy implementations which
rely on ACPIBoard HOB to fill up segment info. So if UplSegmentInfo Hob
is not found we try and look for other hob.

We need to let UEFI know that there are cetain memory types
which are special purpose (CXL/HBM) etc and we may want to
avoid using them for UEFI purposes. Hence UPL needs to know
about such memory types.

Option node provides info that is to be consumed by during
metadata creation for other nodes like root bridge; pci-enum-done
etc. Handle that dependency by storing option values in a variable
and then apply it during post processing. Ideally such cross node
dependency should be avoided in design. Scope for futher improvements.
