Use the correct PCD type for PcdPlatformBootTimeOut so it gets wired up
to the Timeout EFI variable automatically, which is how the boot manager
stores the timeout preference.
Note that this changes the default to 5 seconds, which appears to be
common across platforms.

Alex reports that the cache invalidation performed by
ArmVirtMemoryInitPeiLib takes a non-negligible amount of time at boot.
This cache invalidation used to be necessary to avoid inconsistencies
between the CPU's cached and uncached views of the permanent PEI memory
region, given that the PEI phase is where the MMU gets enabled.
The only allocations done from permanent PEI memory with the MMU off are
pages used for page tables, and since commit 748fea6279
("ArmPkg/ArmMmuLib AARCH64: invalidate page tables before populating
them"), each of those is invalidated in the caches explicitly, for
reasons described in the patch's commit log. All other allocations done
in PEI are either from temporary PEI memory, which includes the stack,
or from permanent PEI memory but after the MMU has been enabled.
This means that the cache invalidation in ArmVirtMemoryInitPeiLib is no
longer necessary, and can simply be dropped.

A Configuration Manager that uses the Dynamic Tables framework

This Configuration Manager uses the FdtHwInfoParser module to
parse the Kvmtool Device Tree and generate the required

Therefore, enable ACPI table generation for Kvmtool.

Add Configuration Manager to enable ACPI tables for Kvmtool
firmware. The Configuration Manager for Kvmtool uses the DT
Hardware Information Parser module (FdtHwInfoParser) to parse
the DT provided by Kvmtool. The FdtHwInfoParser parses the DT
and invokes the callback function HW_INFO_ADD_OBJECT to add
the Configuration Manager objects to the Platform Information
repository.
The information for some Configuration Manager objects may not
be available in the DT. Such objects are initialised locally
by the Configuration Manager.
Support for the following ACPI tables is provided:

In NOOPT and DEBUG builds, if "PcdMaximumLinkedListLength" is nonzero,
then several LIST_ENTRY *node* APIs in BaseLib compare the *full* list

This turns the time complexity of node-level APIs from constant to linear,
and that of full-list manipulations from linear to quadratic.
(See some example OVMF numbers in the previous patch.)
Checking list lengths against an arbitrary maximum -- default value, and
current ArmVirtPkg setting: 1,000,000 -- seems useless even in NOOPT and

Some UEFI shell commands read and write files in chunks. The chunk size is
given by "PcdShellFileOperationSize", whose default in
"ShellPkg/ShellPkg.dec" is 4KB (0x1000).
The virtio-fs daemon of QEMU advertizes a 128KB maximum buffer size by
default, for the FUSE_WRITE operation.
By raising PcdShellFileOperationSize 32-fold, the number of FUSE write
requests shrinks proportionately, when writing large files. And when a
Virtio Filesystem is not used, a 128KB chunk size is still not
particularly wasteful.

"vm_image: 'ubuntu-latest'" now refers to Ubuntu Focal (20.04LTS), not
Ubuntu Bionic (18.04LTS), according to
<https://github.com/actions/virtual-environments/issues/1816>.
In Focal, the "qemu" package is a dummy package with no dependencies, and
so the actual emulators are not pulled in. Compare:
https://packages.ubuntu.com/bionic/qemuhttps://packages.ubuntu.com/focal/qemu
This causes CI runs to fail.
It would be best to switch to the "qemu-system" package name, which
continues to depend on the emulators:
https://packages.ubuntu.com/bionic/qemu-systemhttps://packages.ubuntu.com/focal/qemu-system
However, while that package does make the emulators available, the
emulators crash. So for now, stick with the previous Ubuntu environment,
which continues to be supported, per
<https://github.com/actions/virtual-environments/issues/1816>.

The new MACRO ENABLE_MD5_DEPRECATED_INTERFACES
would be introduced to enable MD5. Make the
definition ahead of the change to avoid build
error after the MACRO changed.

Kvmtool is a virtual machine manager that can be used
to launch guest VMs. Support for Kvmtool virtual
platform has been added to ArmVirtPkg.
Add kvmtool to the ArmVirtPkg dictionary to prevent
the CI Spell check plugin from failing.

Kvmtool emulates a MC146818 RTC controller in the
MMIO space. To support this the MC146818 RTC driver
PcatRealTimeClockRuntimeDxe has been updated to
support MMIO accesses. PCDs for RTC Index and
Target register base addresses in the MMIO space
have been introduced. The KvmtoolRtcFdtClientLib
reads the MC146818 RTC MMIO base address region
from the Kvmtool device tree and updates the
Index and Target register PCDs.
As these PCDs are defined in PcAtChipsetPkg.dec,
this patch updates the CI script to add this
dependency.

Kvmtool is a virtual machine manager that enables hosting
KVM guests. Kvmtool emulates certain devices like serial
port, RTC, etc. essentially providing a virtual platform.
This patch adds support for kvmtool virtual platform.
Following is a brief description of the firmware
implementation choices:
- Serial Port: 16550 UART
On some platforms the 16550 UART is interfaced using
PCI. Therefore, the 16550 Serial port library is
dependent on the PCI library. The 16550 UART driver
checks the Device ID represented using the PCD
gEfiMdeModulePkgTokenSpaceGuid.PcdSerialPciDeviceInfo
to determine if the UART is behind PCI.
If the Device ID is 0xFF then the serial 16550 UART
is not behind PCI.
On Kvmtool the Serial 16550 UART is not behind PCI,
and therefore a combination of BasePciLibPciExpress
and BasePciExpressLib is used to satisfy the PCI
library dependency.
The PcdSerialPciDeviceInfo is also set to 0xFF to
indicate that the Serial 16550 UART is not behind
PCI. The PCD PcdSerialUseMmio is also set to TRUE
to indicate MMIO accesses are required for the
UART registers.
Additionally two instances of PlatformHookLibs are
provided EarlyFdt16550SerialPortHookLib and
Fdt16550SerialPortHookLib to patch the
PcdSerialRegisterBase so that BaseSerialPortLib16550
and retrieve the base address of the 16550 UART.
- Dependency order for Flash
FaultTolerantWriteDxe makes use of PCDs (e.g.
PcdFlashNvStorageFtwSpareBase64 etc.), which in
case of kvmtool will be evaluated based on the CFI
flash base address read from the DT. These variables
are populated in the NorFlashPlatformLib loaded by
ArmVeNorFlashDxe.
This results in a dependency issue with
FaultTolerantWriteDxe. To resolve this make the
NorFlashPlatformLib as a library dependency for
FaultTolerantWriteDxe.
- RTC Controller
A separate patch updates the MC146818 RTC controller
driver to support MMIO accesses.
A KvmtoolRtcFdtClientLib has been introduced to
extract the base addresses of the RTC controller
from the platform device tree and map the RTC
register space as Runtime Memory.

The PlatformPeim() in the PlatformPeiLib is invoked
by the PrePiMain() and provides the platform an
opportunity to setup the plaform specific HOBs.
This PlatfromPeiLib initialises the Kvmtool platform
HOBs like the Fdt, 16550BaseAddress, etc.

The BaseSerialPort16550 library invokes the
PlatformHookSerialPortInitialize() implemented as
part of the PlatformHook library, to perform platform
specific initialization required to enable use of the
16550 device. The BaseSerialPort16550 library uses
the PcdSerialRegisterBase to obtain the base address
of the UART for MMIO operations.
Some VMMs like Kvmtool provide the base address of
the console serial port in the platform device tree.
This patch introduces two instances of the Platform
Hook library:
1. EarlyFdt16550SerialPortHookLib - parses the
platform device tree to extract the base
address of the 16550 UART and update the PCD
PcdSerialRegisterBase.
2. Fdt16550SerialPortHookLib - reads the GUID
Hob gEarly16550UartBaseAddressGuid (that caches
the base address of the 16550 UART discovered
during early stages) and updates the PCD
PcdSerialRegisterBase.
Note:
a. The PCD PcdSerialRegisterBase is configured
as PatchableInModule.
b. A separate patch introduces a PlatformPeiLib
that trampolines the 16550 UART base address
from the Pcd PcdSerialRegisterBase to the
GUID Hob gEarly16550UartBaseAddressGuid.
