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FV3 HOBs have superceded FV2 HOBs for describing extracted FVs.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.

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:

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.

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

Introduce a driver that allows users to disable the EFI Memory Attribute
protocol through an HII setup option, in order to work around a broken
version of rhboot's shim used in some distros (e.g. CentOS Stream 9)
which incorrectly invokes the protocol and results in a Synchronous
Exception.
Default is enabled, which can also be overridden at build time by
changing `gEmbeddedTokenSpaceGuid.PcdMemoryAttributeEnabledDefault`.
It is only applicable to ARM64 and there isn't any other technical
reason for disabling this security feature.

The RealTimeClockLib class header in edk2 mistakenly declares a function
called LibRtcVirtualNotifyEvent(). No component ever calls this function
crossing module boundaries; all RealTimeClockLib instances in edk2 and
edk2-platforms are supposed to register (and do register) their
SetVirtualAddressMap() notification functions.
At this point, the word "LibRtcVirtualNotifyEvent" no longer occurs in any
of edk2, edk2-platforms, even edk2-non-osi, except the library class
header proper. Remove the LibRtcVirtualNotifyEvent() function declaration.

For the implementation which utilizes libfdt provided in EmbeddedPkg
however it uses strncmp function in the libfdt helper library,
libfdt_env.h should provide the macro implied with edk2 strncmp
implementation.
The example is RISC-V OpenSBI library. edk2 RISC-V port uses OpenSBI
library and incorporate with edk2 libfdt. edk2 libfdt_env.h provides
the necessary macros to build OpenSBI which uses fdt functions in edk2

strncmp function which is not defined in edk2 libfdt_env.h. This commit

These can be used, for instance, to automate the population of an SMBIOS
Type 0 BIOS Release Date when building a UEFI firmware (which is how we
plan to use these macros for the Raspberry Pi platform).
These macros should work for any compiler that follows ISO/IEC 9899, but
we add a check for the compiler we have tested to be on the safe side.
Note that we decided against adding a #error or #warn for compilers that
haven't been validated, as we don't want to introduce breakage for people
who may already be using the header with something else than gcc, MSVC or
Clang. Instead, we expect those to send a patch that adds their compiler
to the list, once they have tested the macros there.

predefined boot options in platform driver. This interface
will be used in ArmPkg/PlatformBootManagerLib.

This driver is used to simulate a keyboard. For example, user
could read GPIO setting or data from RAM address. If the value
matches the expected pattern, it could trigger a key pressed
event.
User needs to implement hooks of PLATFORM_VIRTUAL_KBD_PROTOCOL.
There're 4 hooks in this protocol.
Register(): Quote the interface that user needs. For example, user
needs to locate GPIO protocol if he wants to simulate a GPIO value
as a key.
Reset(): Do the initialization before reading value.
Query(): Read value. If the value matches the expected pattern,
trigger a key pressed event.
Clear(): Clean the value if necessary.

Some platforms don't format a variable store template at build time;
instead they format the non-volatile varstore flash chip during boot,
dynamically. Introduce NvVarStoreFormattedLib to enable such platforms to
delay the "variable read" service drivers until the platform specific
module(s) report that the variable store has been formatted.
The platform-specific module that performs the formatting during startup
is usually an FVB or MM FVB driver. Under the proposed scheme, it becomes
responsible for installing gEdkiiNvVarStoreFormattedGuid with a NULL
interface in the protocol database. In turn, the platform DSC will hook
NvVarStoreFormattedLib into the variable service driver, to make the
latter wait for the FVB driver. Platforms that need not delay the variable
service driver like this may still use the same FVB driver;
gEdkiiNvVarStoreFormattedGuid will simply be ignored.

Commit a099239015eb ("EmbeddedPkg/FdtLib: Update FdtLib to v1.4.5")
updated our FdtLib implementation to a more recent upstream version,
but omitted fdt_overlay.c due to its ambiguous licensing situation.
This has been resolved now, so take the latest upstream version of
the file (which received no other modifications in the mean time)
and add it to FdtLib.
Note that fdt_overlay.c has a dependency on strtoul() which EDK does
not provide natively, so add a private implementation that wraps the
BaseLib routines that do roughly the same.

Delete a bunch of Pcds, a guid, and a related header file - probably Ebl
