The FDT client protocol methods dealing with "reg" properties return
the size of a "reg" element. Currently, we have hardcoded this as '8',

different values, have a single 'reg' element size is not unambiguous,

In general, on an ARM system, mapping normal memory as device memory may
have unintended side effects, given that unaligned accesses or loads and
stores with special semantics (e.g., load/store exclusive) may fault or
may not work as expected.
Under KVM, the situation is even worse, since the host may not expect the
guest to perform uncached accesses, and so writes to such an uncached
region may get lost completely.
Since the only safe mapping type under KVM is EFI_MEMORY_WB, remove all
other memory type attributes.

functionality was not added to QemuBootOrderLib, because it was (and is)
independent from QEMU and fw_cfg.)
Remove any boot options that point to binaries built into the firmware and

- FvMain's base address or size changed (historical -- see commit
e191a3114f),
- FvMain's FvNameGuid changed,
- the FILE_GUID of the pointed-to binary changed,
- the referenced binary is no longer built into the firmware.
For example, multiple such "EFI Internal Shell" boot options can coexist.
They technically differ from each other, but may not describe any built-in
shell binary exactly. Such options can accumulate in a varstore over time,
and while they remain generally bootable (thanks to the efforts of
BmGetFileBufferByFvFilePath()), they look bad.

Turns out Gary's argument in 14b2ebc30c is not only valid for Xen. The
same situation arises with QEMU if:
- the user specifies no boot order via fw_cfg at all (so QemuBootOrderLib
won't touch the boot order), and
- the varstore file has just been created from the varstore template.
In this case the user is dropped to the UEFI shell (because the shell is
registered earlier than all the auto-generated options), which is likely
not what the user wants.

In the course of porting ArmVirtPkg to the MdeModulePkg BDS, commit
1f73aef50c
ArmVirtPkg/PlatformBootManagerLib: add EnableQuietBoot & DisableQuietBoot
open-coded the EnableQuietBoot() function (and its dependencies / friends)
from IntelFrameworkModulePkg BDS.
This code duplication can be avoided; the functionality is available from
the following three libraries in MdeModulePkg:
- BootLogoLib: provides the BootLogoEnableLogo() function. It does not
provide the internal ConvertBmpToGopBlt() function -- that one is
delegated to ImageDecoderLib (function DecodeImage()).
- ImageDecoderLib: a general library that registers decoder plugins for
specific image formats, and provides the generic DecodeImage() on top.
- BmpImageDecoderLib: one of said decoder plugins, for handling BMP images
(which is the format of our logo).
In this patch, we revert 1f73aef50c, and atomically incorporate the
above libraries. This is inspired by Nt32Pkg commit 859e75c4fc42:

QemuBootOrderLib can only filter out and reorder boot options; it cannot
create boot options. It relies on Platform BDS to auto-generate all
possible boot options first (for example, for new virtual devices that
have been configured since the last run of the virtual machine). Then it
will decide, case-by-case, whether each of those auto-generated boot
options should be preserved (and at what position), or removed.
Thus far, the only implementation of SetBootOrderFromQemu(), used in
connection with IntelFrameworkModulePkg BDS, has expected said complete
boot option list as an input parameter:
BdsEntry() [IntelFrameworkModulePkg/Universal/BdsDxe/BdsEntry.c]
// create empty list
InitializeListHead (
&BootOptionList
)
PlatformBdsPolicyBehavior( [ArmVirtPkg/Library/PlatformIntelBdsLib/IntelBdsPlatform.c]
BootOptionList
)
BdsLibConnectAll()
BdsLibEnumerateAllBootOption(
BootOptionList
)
// at this point, BootOptionList starts with the preexistent boot
// options, and ends with the auto-generated options
SetBootOrderFromQemu( [OvmfPkg/Library/QemuBootOrderLib/QemuBootOrderLib.c]
BootOptionList
)
// write out changed boot order to UEFI variables
// The "BootOrder" variable may have changed. Refresh BootOptionList
// from it, and return it to BdsEntry().
With MdeModulePkg BDS, a BootOptionList is not propagated from BdsEntry()
to SetBootOrderFromQemu() and back. All processing is based directly on
the underlying "BootOrder" and "Boot####" variables.
In OvmfPkg, commit d27ec22d11 introduced a new instance of
QemuBootOrderLib, called QemuNewBootOrderLib. It is based on
UefiBootManagerLib, and rather than taking a complete BootOptionList as a
parameter, it expects that the "BootOrder" and "Boot####" variables are
complete in the above sense.
Rebase the boot order manipulation to UefiBootManagerLib and
QemuNewBootOrderLib, while keeping the requirement satisfied, like this:
BdsEntry() [MdeModulePkg/Universal/BdsDxe/BdsEntry.c]
PlatformBootManagerAfterConsole() [ArmVirtPkg/Library/PlatformBootManagerLib/PlatformBm.c]
EfiBootManagerConnectAll()
EfiBootManagerRefreshAllBootOption()
// at this point all auto-generated options exist at the end of
// "BootOrder"
SetBootOrderFromQemu() [OvmfPkg/Library/QemuNewBootOrderLib/QemuBootOrderLib.c]
// read boot options from "BootOrder" and "Boot####", then
// manipulate them
This patch parallels OvmfPkg commit 04fe914ba5.
Once the USE_OLD_BDS fallback is removed from OvmfPkg, the parameter list
of the SetBootOrderFromQemu() prototype can be updated to VOID.

This implements a library ArmVirtPL031FdtClientLib which is intended to
be incorporated into RealTimeClockRuntimeDxe via NULL library class
resolution. This allows us to make RealTimeClockRuntimeDxe depend on the
FDT client protocol, and discover the PL031 base address from the device tree
directly rather than relying on VirtFdtDxe to set the dynamic PCDs.
The NULL library class resolution approach to strictly order production and
consumption of dynamic PCDs is not generally safe in cases such as this one,
where the producer and the consumer of the PCD are both libraries. However,
since the PCD is produced in this library's constructor, and the consumer
library's constructor 'LibRtcInitialize' is not a 'true' constructor (it is
invoked explicitly by RealTimeClockRuntimeDxe), this case is guaranteed to
be safe after all.

Make BaseCachingPciExpressLib depend on PciPcdProducerLib, so that we
have a chance to populate PcdPciExpressBaseAddress based on the contents
of the device tree.
Also update the platforms under ArmVirtPkg that support PCI to use the
special MAX_UINT64 value as the build time default for
PcdPciExpressBaseAddress.

This implements a library FdtPciPcdProducerLib which is intended to
be incorporated into modules that consume the PCI related dynamic PCDs
PcdPciExpressBaseAddress and PcdPciDisableBusEnumeration, either via NULL
library class resolution or via a direct dependency (for other libraries
or modules in ArmVirtPkg). This allows us to make them depend on the FDT
client protocol, and populate these PCDs based on the presence and the
contents of a 'pci-host-ecam-generic' DT node.
This also overloads the meaning of PcdPciExpressBaseAddress, which we will
set to MAX_UINT64 to signify that the actual values of these two PCDs have
not been assigned yet.

Make this library depend on the FDT client protocol to access the
host supplied device tree directly rather than depending on VirtFdtDxe
to set them using dynamic PCDs.
Since this library is used by several drivers (BdsDxe, SmbiosPlatformDxe,
SmbiosDxe and QemuFwCfgAcpiPlatformDxe), we will end up parsing the device
tree and the fwcfg node at least four times. However, no dynamic PCDs are
involved anymore, and will even be removed completely in a subsequent
patch. So the conversion is not optimal, but guaranteed to be safe.

Instead of relying on VirtFdtDxe to detect the PSCI method, move our
EfiResetSystemLib to the FDT client protocol to interrogate the device
tree directly.
Since this library is only consumed by EmbeddedPkg/ResetRuntimeDxe, and
considering that the PCD is no longer set, and even removed completely in a
subsequent patch, this conversion is guaranteed to be safe.

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.
