Move the ACPI table helper macros from EmbeddedPkg's AcpiLib.h to
MdeModulePkg's AcpiHelperMacros.h.
These macros describe ACPI data initializers and do not depend on the
AcpiLib library interface. Keeping them in AcpiLib.h forces users that
only need the macros to include the AcpiLib library header unnecessarily.
Place the macros in a common MdeModulePkg public header so ACPI table
producers can include the macro definitions directly without implying
use of AcpiLib.
The companion edk2-platforms change is:
"Global: Include AcpiHelperMacros.h for ACPI helper macros"
Tested:
DynamicTablesPkg: X64/AARCH64 DEBUG/RELEASE/NOOPT

EmbeddedPkg's PrePiLib and OvmfPkg's PeilessStartupLib (which
uses PrePiLib) only produce FV2 HOBs for extracted FVs. However,
FV3 HOBs have superceded FV2 HOBs for describing extracted FVs.
This commit updates both of these libs to also produce FV3 HOBs,
following PEI's pattern of producing an FV, FV2, and FV3 HOB for
each extracted FV.
Eventually, only FV3 HOBs will be produced, so this paves the way
for that.

PrePiLib is incorrectly producing FV2 HOBs. The FvName field of
the FV2 HOB is intended to be the parent FV's name. This way the
HOB consumer phase can identify when an FV has already been
extracted: if the file name of the extracted FV and the parent
FV name match in the FV2 HOB.
With the incorrect FvName, DXE will re-extract the already
extracted FV, which can be a large performance hit (some platforms
we have seen ~1 second).
This requires an update to FfsProcessFvFile to pass the parent
FV handle through so the FV2 HOB can be correctly produced.
OvmfPkg consumers are also updated.

FfsGetVolumeInfo() in PrePiLib does not zero the VolumeInfo
buffer before writing to it. However, it has some fields that
are expected to be zero if certain conditions are not met.
For example, the FvName is expected to be all 0's if the
extended header is not present in the FV. Currently,
the FvName field will point to garbage if the caller does
not zero the buffer first.
Flip the expectation and have FfsGetVolumeInfo() zero the
buffer before it writes to it.

PrePiLib only searches for the existence of an FV2 HOB to
determine if an FV has already been extracted. However,
FV2 HOBs have been superceded by FV3 HOBs for describing extracted
FVs.
This commit updates PrePiLib to check for the existence of either
an FV2 or FV3 HOB for this FV and skips extracting if either is
found.

GBL (Generic Bootloader) is Google's UEFI-based bootloader for Android.
It runs as an EFI application and delegates board- and platform-specific
operations to the underlying firmware through GBL-defined EFI protocols.
This patch adds only the header definitions (GUIDs, revisions and
interfaces) for those protocols, covering Android Verified Boot, AVF,
A/B boot-control, boot-memory, debug, Fastboot (and its transport) and
OS configuration.
For details, see:

Replace manual alignment checks with IS_ALIGNED() and
ADDRESS_IS_ALIGNED().
Convert the following bitmask and modulo forms:
- ((E & ((PowOf2Expr) - ONE)) == ZERO)
- ((E & ((PowOf2Expr) - ONE)) != ZERO)
- ((E % (PowOf2Expr)) == ZERO)
- ((E % (PowOf2Expr)) != ZERO)
to the corresponding helper macro forms:
+ IS_ALIGNED (E, PowOf2Expr)
+ !IS_ALIGNED (E, PowOf2Expr)
PowOf2Expr is limited to known power-of-two expressions, including
SIZE_* and BASE_* macros, EFI_PAGE_SIZE, CPU_STACK_ALIGNMENT,
RUNTIME_PAGE_ALLOCATION_GRANULARITY, sizeof() of UEFI integer types
(e.g. BOOLEAN, CHAR16, UINT32, UINTN) and pointer types, and 1 << E1
expressions.
Address checks that cast the checked value to UINTN are written with
ADDRESS_IS_ALIGNED().
The change was generated with the Coccinelle semantic patch below.

This reverts commit 57230fff6b39a665485be1bd43ec608d412ba6fb.
RealTimeClockLib is not a generic library class that is intended to be
used widely to get access to the RTC when the associated runtime
services are not available in the calling context.
The purpose of RealTimeClockLib is to abstract the underlying hardware
access from the generic RealTimeClockRuntimeDxe driver, which backs the
runtime services.
This means it does not belong in a different package; it belongs in the
same package as the driver.

Symptom:Unsafe typecasting may lead to out‑of‑bound memory access
RootCause: FileSize and FileLength are declared as
UINT32 and masked with 0x00FFFFFF to store only the lower 24 bits.
Although this approach yields the correct result,
it introduces a potential risk due to unsafe typecasting and
dereferencing.
Solution: Using the predefined macro FFS_FILE_SIZE()
from MdePkg\Include\Pi\PiFirmwareFile.h,
which safely performs the same operation by reconstructing
the size using individual byte access.
This commit also addresses the fix for coverity isssue "OVERRUN"

Replace traditional `#ifndef`/`#define`/`#endif` include guards with
`#pragma` once.
`#pragma once` is a widely supported preprocessor directive that
prevents header files from being included multiple times. It is
supported by all toolchains used to build edk2: GCC, Clang/LLVM, and
MSVC.
Compared to macro-based include guards, `#pragma once`:
- Eliminates the risk of macro name collisions or copy/paste errors
where two headers inadvertently use the same guard macro.
- Eliminate inconsistency in the way include guard macros are named
(e.g., some files use `__FILE_H__`, others use `FILE_H_`, etc.).
- Reduces boilerplate (three lines replaced by one).
- Avoids polluting the macro namespace with guard symbols.
- Can improve build times as the preprocessor can skip re-opening the
file entirely, rather than re-reading it to find the matching
`#endif` ("multiple-include optimization").
- Note that some compilers may already optimize traditional include
guards, by recognzining the idiomatic pattern.
This change is made acknowledging that overall portability of the
code will technically be reduced, as `#pragma once` is not part of the
C/C++ standards.
However, this is considered acceptable given:
1. edk2 already defines a subset of supported compilers in
BaseTools/Conf/tools_def.template, all of which have supported
`#pragma once` for over two decades.
2. There have been concerns raised to the project about inconsistent
include guard naming and potential macro collisions.
Approximate compiler support dates:
- MSVC: Supported since Visual C++ 4.2 (1996)
- GCC: Supported since 3.4 (2004)
(http://gnu.ist.utl.pt/software/gcc/gcc-3.4/changes.html)
- Clang (LLVM based): Since initial release in 2007

When allocating Runtime memory the MemoryAllocation HOB's length needs
to meet the alignment requirements of Runtime memory. On AARCH64
architectures this alignment is not the default of 4KB.
Instead it is set by the RUNTIME_PAGE_ALLOCATION_GRANULARITY
definition, which is 64KB.
This change enforces the RUNTIME alignment as part of generating the
MemoryAllocationHob for runtime memory types.

ArmVirtPkg uses PrePiMemoryAllocationLib and PeiServicesLib in
the same module. PeiServicesLib depends on MemoryAllocationLib,
fulfilled by PrePiMemoryAllocationLib in this instance. However,
PeiServicesLib uses AllocateCopyPool() which is not provided in
PrePiMemoryAllocationLib. CLANGPDB AARCH64 finds this as a link
error. Other toolchains are optimizing the call out since that
code path is not used in this module.
This adds AllocateCopyPool() to PrePiMemoryAllocationLib to
satisfy the dependency.
