Since this library is only consumed by EmbeddedPkg/ResetRuntimeDxe, and

Instead of relying on VirtFdtDxe to populate the GIC related PCDs, move
this handling to our implementation of ArmGicArchLib, and retrieve the
required DT info using the new FDT client protocol.
This removes one of the reasons we need to load VirtFdtDxe first using
an 'A PRIORI' declaration in the platform FDF.
As Laszlo kindly confirms:
So, ultimately, the only user of this library instance is
"ArmPkg/Drivers/ArmGic/ArmGicDxe.inf". ... Indeed, checking the build
report file for ArmVirtQemu (AARCH64), I find ArmVirtGicArchLib (and
ArmGicLib too) only under "ArmPkg/Drivers/ArmGic/ArmGicDxe.inf".
which means that the constructor is only invoked once, and so the dynamic
PCDs are set in time for ArmGicDxe to consume them, and never afterwards.

Unlike Linux on x86, which typically honors the PCI configuration performed
by the firmware, Linux on ARM assumes that the PCI subsystem needs to be
configured from scratch. This is not entirely unreasonable given the
historical background of embedded systems using very basic bootloaders,
but is no longer tenable with Linux on arm64 moving to UEFI and ACPI in the
server space. For this reason, PCI support in the arm64 kernel running under
ACPI is likely to move to the x86 model of honoring the PCI configuration
done by the firmware.
So let's align with that in our DT based configuration as well, and set the
/chosen/linux,pci-probe-only property to 1 in the Device Tree before we
hand it to the OS.
In case we are exposing an emulated VGA PCI device to the guest, which may
subsequently get exposed via the Graphics Output protocol and driven as an
efifb by the OS, this ensures the PCI resource allocations for the framebuffer
are not overridden, since that would cause the framebuffer to stop working.

The legacy 32-bit SMBIOS entry point has little use on AARCH64 systems,
since many such systems have no 32-bit addressable physical RAM, and so
OSes that implement SMBIOS will have to be able to deal with the 64-bit
entry point anyway.
Given that the OS will map main memory in 1 GB chunks if it can, and that
punching a page sized hole (e.g., for SMBIOS data) into it will result in
the whole 1 GB chunk being mapped using 2 MB and 4 KB blocks instead, it
is important to group memory reservations from the OS as much as we can,
and allocating below 4 GB for no good reason interferes with that.
This is especially important under virtualization, considering that each
*level* of lookup at stage 1 (the guest virtual page table) will result in
a full page table walk at stage 2 (the guest PA to host PA mapping).
So expose only the 64-bit entry point when the SMBIOS tables adhere to
version 3.0 or later.

The ID mapping routines on virtual platforms simply map the entire
hardware supported physical address space as device memory, and then
punch some holes for regions that need to be mapped cacheable.
On virtual platforms hosted on CPUs that support a large physical
address range, this may result in a lot of overhead, i.e., 4 KB of page
tables for each 512 GB of address space, which quickly adds up (i.e.,
2 MB for the architectural maximum of 48 bits).
Since there may be a platform specific limit to the size of the (I)PA
space that is not reflected by CPU id registers, restrict the range of
the ID mapping to gEmbeddedTokenSpaceGuid.PcdPrePiCpuMemorySize bits.
This makes sense by itself, since we cannot manipulate mappings above
that limit anwyay (because they are not covered by GCD), and it allows
the PCD be set to a lower value by platforms whose (I)PA space is
smaller than the hardware supported maximum.

The ARM architecture version 7 and later mandates that device mappings
have the XN (non-executable) bit set, to prevent speculative instruction
fetches from read-sensitive regions. This implies that we should not map
regions as device if we want to execute from them, so the NOR region that
contains our FD image should be mapped as normal memory instead.
The MMU code deals correctly with overlapping ARM_MEMORY_REGION_DESCRIPTOR
entries, and later entries in the array take precedence over earlier ones.
So simply add an entry to the end of the array that overrides the mapping
attributes of the FD image, wherever it resides.

The TFTP command is easy to use, it has very nice documentation
(accessible with "HELP TFTP" in the shell), and it's a very versatile
tool for downloading files from the host to the guest, via virtual
network, while the guest is in the UEFI shell.
Even better, enabling this command in the shell increases the
uncompressed FVMAIN size only by 8192 bytes, in my AARCH64 build of
VirtArmQemu.dsc, and the final size increase (after LZMA compression)
that is visible in the FVMAIN_COMPACT volume is merely 1976 bytes.

Commit SVN r18503 ("MdeModulePkg DxeCore: Take the range in resource
HOB for PHIT as higher priority") changed the GCD init logic to take
the sum of the region sizes in gMemoryTypeInformation[] into account
when estimating the minimal amount of memory needed to boot the system.
Unfortunately, as an unintended side effect, this change results in boot
failures of ArmVirtQemu when running with QEMU's default memory size of
128 MB. The reason is that the sum of the gMemoryTypeInformation region
sizes plus the size of the inital PEI region exceeds 128 MB. Since we do
not actually need to preallocate 20,000 pages' worth of BootServicesData
memory, reduce this figure to the more reasonable 12,000.

According to the UEFI spec, EFI_EVENT_GROUP_READY_TO_BOOT "is notified by
the system when the Boot Manager is about to load and execute a boot

variable reclaim and (optionally) installs variable usage statistics as
a vendor config table;
- OnReadyToBoot() in

The current implementation of ArmGicGetSupportedArchRevision ()
that is used by all ARM platforms is entirely stateless (in order
to support being executed from flash) so it needs to interrogate
the hardware for the supported GIC revision upon each invocation.
However, this statelessness is only needed for SEC type modules;
in all other cases, we could easily determine the GIC revision once,
and store the result in a global variable.
In preparation of having separate early and normal versions, this patch
introduces the ArmGicArchLib library class and default implementation,
and moves the existing ArmGicGetSupportedArchRevision () into it.

(This patch parallels OvmfPkg commit 37baf06b (SVN r17676).)
PcdSmbiosVersion controls the version number of the SMBIOS entry point
table (and other, related things) that the universal
"MdeModulePkg/Universal/SmbiosDxe" driver, providing EFI_SMBIOS_PROTOCOL,
installs.
The "virt" machine type of QEMU generates SMBIOS payload for the firmware
to install. The payload includes the entry point table ("anchor" table).
OvmfPkg/SmbiosPlatformDxe cannot install the anchor table (because that is
the jurisdiction of the generic "MdeModulePkg/Universal/SmbiosDxe"
driver); however, we can parse the entry point version from QEMU's anchor
table, and instruct "MdeModulePkg/Universal/SmbiosDxe" to adhere to that
version.
As default for PcdSmbiosVersion we should keep the current 0x0300 value
(ie. SMBIOS 3.0) from "MdeModulePkg/MdeModulePkg.dec"; that spec version
was specifically created for ARM / AARCH64 needs.

Many universal DXE drivers in edk2 can be controlled by setting dynamic
PCDs. Such a PCD must be set before the consumer DXE driver is dispatched.
(In general we assume that the DXE driver will consume the PCD in its
entry point, or in the constructor of a library instance it links against.
In special cases this requirement can be relaxed a bit, if we know that
the DXE driver accesses the PCD only in a protocol member function that it
exports.)
On the QEMU platform, the PCD values to be set for the universal drivers
are frequently derived from fw_cfg files that QEMU exports.
In OvmfPkg we tend to handle this in the following way:
- For IA32 and X64, OvmfPkg provides a QemuFwCfgLib instance that is
usable in PEI.
- In PlatformPei, fw_cfg files can be loaded and transformed to PCD
values.
- Any DXE driver is bound to be dispatched after the PEI phase is done.
(In specific cases other ordering solutions might be possible, via Depex
or protocol notify, etc.)
In ArmVirtPkg/ArmVirtQemu, things differ a bit:
- We don't have an ArmVirtPkg-specific ("Platform") PEIM. This is actually
a good thing for now, so let's not introduce one just for this purpose.
- Even if we had such a PEIM, it could not easily access fw_cfg: the MMIO
addresses of the fw_cfg device are available only in the DTB that QEMU
exports.
(Accordingly, our QemuFwCfgLib instance is restricted to DXE_DRIVER
modules: VirtFdtDxe parses the DTB, stores the fw_cfg addresses in PCDs,
and then QemuFwCfgLib's constructor fetches those PCDs.)
There are some examples in ArmVirtPkg where early code is forced to
parse the DTB manually, but those examples are all painful, and our goal
here (controlling universal DXE drivers) doesn't justify more of that
pain.
Therefore, introduce a separate, minimal DXE driver that is dispatched
strictly after VirtFdtDxe (so that it can use QemuFwCfgLib), and strictly
before other DXE drivers (so that it can set dynamic PCDs for them).
Because VirtFdtDxe is already ordered with the APRIORI DXE file, it is
simplest to do the same for the new driver.
Actual fw_cfg files and PCDs shall be accessed in future patches.

Change default terminal type to be consistent with default
ConIn/ConOut device path, which is now determined by TTY_TERMINAL

I can't say this is a bug, as we can pass the whole console device
path to ConnectController, and TerminalDxe driver will pick up the
terminal in the remaining device path. However, in rare circumstances,
the console devices may be disconnected with the driver, and they will
be ignored by ConPlatformDxe until we pass the device path explicitly
just as BDS.
Changing default terminal type to be the same with console device
path could help serial terminal be reconnected with normal connect

Add a fixed pointer PCD to allow build-time selection of VT100 or TTY terminal
type. The default remains VT100 emulation.
Add support for building the ARM QEMU platforms with the TTY terminal
with the "-D TTY_TERMINAL" build option.

The linker script is specific to GCC toolchain.
So, this script will not work with other linkers
(eg: ARM Toolchain Linker, Microsoft Linker, etc).

This fixes the declaration and definition of mSystemMemoryEnd so that it
is correctly annotated as a non-function symbol. Also adds the ASM_PFX
prefix, which is empty on AARCH64 but should be included for correctness.

This fixes the ArmVirtXen build that was broken by r17835, which adds
a global variable mSystemMemoryEnd which is shared between a module
and a library it depends on.
Add the same global variable to the relocatable PrePi used by ArmVirtXen.

This adds the 64 KB alignment overlay linker script to the linker
command line of DXE_RUNTIME_DRIVER modules. This makes these modules
compatible with the new Properties Table feature by aligning the .text
and .data sections to 64 KB.

AuthVariableLib and TpmMeasurementLib library classes are now linked with
MdeModulePkg/Universal/Variable/RuntimeDxe/VariableRuntimeDxe.inf
to optionally support secure variables.
For ArmVirtPkg,
link AuthVariableLib and DxeTpmMeasurementLib in SecurityPkg
when SECURE_BOOT_ENABLE = TRUE,
and link AuthVariableLibNull and TpmMeasurementLibNull in MdeModulePkg
when SECURE_BOOT_ENABLE = FALSE.

Currently, the ArmVirtPkg platforms built with the Intel BDS fail
to signal the end-of-DXE event 'gEfiEndOfDxeEventGroupGuid' when
entering the BDS phase, which results in some loss of functionality,
i.e., variable reclaim in the VariableDxe drivers, and the splitting
of the memory regions that is part of the recently added UEFI 2.5
properties table feature.
As discussed on the edk2-devel mailing list here:
http://thread.gmane.org/gmane.comp.bios.tianocore.devel/16088/focus=16109
it is up to the platform BDS to signal that event, since there may be
platform specific ordering constraints with respect to the signalling
of the event that are difficult to honor at the generic level.
So add the SignalEvent () call to PlatformBdsInit () of ArmVirtPkg's
PlatformBdsLib implementation for the Intel BDS.

This is a followup to r17554 ("ArmVirtPkg: increase memory
preallocations to reduce region count") that increases the sizes
of the preallocated regions to account for the footprint of the
crypto and authentication libraries. This is only done if secure
boot is enabled at build time, to prevent imposing a larger minimum
RAM size on non-secure builds.

Both files originate from ArmPlatformPkg.
The copyright notices at the top of "License.txt" have been refreshed as
follows:
- I grepped ArmVirtPkg for "copyright", case-insensitively
- for each copyright holder company, I unified the intervals to the
strictest superset (no absent year was introduced in this process)
- I listed the copyright notices in decreasing order of last contribution
year.
- When a "last contribution year" was shared by several notices, I sorted
those between each other in descending "first contribution year" order.
