Add a library class, and a UEFI_DRIVER lib instance, that are layered on
top of PciCapLib, and allow clients to plug an EFI_PCI_IO_PROTOCOL backend
into PciCapLib, for config space access.
(Side note:
Although the UEFI spec says that EFI_PCI_IO_PROTOCOL_CONFIG() returns
EFI_UNSUPPORTED if "[t]he address range specified by Offset, Width, and
Count is not valid for the PCI configuration header of the PCI
controller", this patch doesn't directly document the EFI_UNSUPPORTED
error code, for ProtoDevTransferConfig() and its callers
ProtoDevReadConfig() and ProtoDevWriteConfig(). Instead, the patch refers
to "unspecified error codes". The reason is that in edk2, the
PciIoConfigRead() and PciIoConfigWrite() functions [1] can also return
EFI_INVALID_PARAMETER for the above situation.
Namely, PciIoConfigRead() and PciIoConfigWrite() first call
PciIoVerifyConfigAccess(), which indeed produces the standard
EFI_UNSUPPORTED error code, if the device's config space is exceeded.
However, if PciIoVerifyConfigAccess() passes, and we reach
RootBridgeIoPciRead() and RootBridgeIoPciWrite() [2], then
RootBridgeIoCheckParameter() can still fail, e.g. if the root bridge
doesn't support extended config space (see commit 014b472053).
For all kinds of Limit violations in IO, MMIO, and config space,
RootBridgeIoCheckParameter() returns EFI_INVALID_PARAMETER, not
EFI_UNSUPPORTED. That error code is then propagated up to, and out of,
PciIoConfigRead() and PciIoConfigWrite().

Add a library class, and a BASE lib instance, that are layered on top of
PciCapLib, and allow clients to plug a PciSegmentLib backend into
PciCapLib, for config space access.
(Side note:
The "MaxDomain" parameter is provided because, in practice, platforms
exist where a PCI Express device may show up on a root bridge such that
the root bridge doesn't support access to extended config space. Earlier
the same issue was handled for MdeModulePkg/PciHostBridgeDxe in commit
014b472053. However, that solution does not apply to the PciSegmentLib
class, because:
(1) The config space accessor functions of the PciSegmentLib class, such
as PciSegmentReadBuffer(), have no way of informing the caller whether
access to extended config space actually succeeds.
(For example, in the UefiPciSegmentLibPciRootBridgeIo instace, which
could in theory benefit from commit 014b472053, the
EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Pci.Read() status code is explicitly
ignored, because there's no way for the lib instance to propagate it
to the PciSegmentLib caller. If the
EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Pci.Read() call fails, then
DxePciSegmentLibPciRootBridgeIoReadWorker() returns Data with
indeterminate value.)
(2) There is no *general* way for any firmware platform to provide, or
use, a PciSegmentLib instance in which access to extended config space
always succeeds.
In brief, on a platform where config space may be limited to 256 bytes,
access to extended config space through PciSegmentLib may invoke undefined
behavior; therefore PciCapPciSegmentLib must give platforms a way to
prevent such access.)

Call Tcg2PhysicalPresenceLibProcessRequest() to process pending PPI
requests from PlatformBootManagerAfterConsole().
Laszlo understanding of edk2 is that the PPI operation processing was
meant to occur *entirely* before End-Of-Dxe, so that 3rd party UEFI
drivers couldn't interfere with PPI opcode processing *at all*.
He suggested that we should *not* call
Tcg2PhysicalPresenceLibProcessRequest() from BeforeConsole(). Because,
an "auth" console, i.e. one that does not depend on a 3rd party
driver, is *in general* impossible to guarantee. Instead we could opt
to trust 3rd party drivers, and use the "normal" console(s) in
AfterConsole(), in order to let the user confirm the PPI requests. It
will depend on the user to enable Secure Boot, so that the
trustworthiness of those 3rd party drivers is ensured. If an attacker
roots the guest OS from within, queues some TPM2 PPI requests, and
also modifies drivers on the EFI system partition and/or in GPU option
ROMs (?), then those drivers will not load after guest reboot, and
thus the dependent console(s) won't be used for confirming the PPI
requests.

Introduce TlsAuthConfigLib to read the list of trusted CA certificates

The fw_cfg file is formatted by the "p11-kit" and "update-ca-trust"
utilities on the host side, so that the host settings take effect in guest

contents are sanity-checked by NetworkPkg/HttpDxe code that was added in

Link TlsAuthConfigLib via NULL resolution into TlsAuthConfigDxe. This sets
EFI_TLS_CA_CERTIFICATE_VARIABLE in time for both
NetworkPkg/TlsAuthConfigDxe (for possible HII interaction with the user)
and for NetworkPkg/HttpDxe (for the effective TLS configuration).
The file formatted by "p11-kit" can be large. On a RHEL-7 host, the the
Mozilla CA root certificate bundle -- installed with the "ca-certificates"
package -- is processed into a 182KB file. Thus, create
EFI_TLS_CA_CERTIFICATE_VARIABLE as a volatile & boot-time only variable.
Also, in TLS_ENABLE builds, set the cumulative limit for volatile
variables (PcdVariableStoreSize) to 512KB, and the individual limit for
the same (PcdMaxVolatileVariableSize) to 256KB.

Use ZeroMem() to initialize (or re-initialize) all fields in temporary
PCI_ROOT_BRIDGE_APERTURE variables to zero. This is not mandatory but
is helpful for future extension: when we add new fields to
PCI_ROOT_BRIDGE_APERTURE and the default value of these fields can
safely be zero, this code will not suffer from an additional
change.

QemuBootOrderLib expects PlatformBootManagerLib to call the following
triplet:
(1) EfiBootManagerConnectAll(),
(2) EfiBootManagerRefreshAllBootOption(),
(3) SetBootOrderFromQemu().
This leads to bad performance, when many devices exist such that the
firmware can drive them, but they aren't marked for booting in the
"bootorder" fw_cfg file. Namely,
(1) EfiBootManagerConnectAll() talks to all hardware, which takes long.
Plus some DriverBindingStart() functions write NV variables, which is
also slow. (For example, the IP config policy for each NIC is stored
in an NV var that is named after the MAC).
(2) EfiBootManagerRefreshAllBootOption() generates boot options from the
protocol instances produced by (1). Writing boot options is slow.
(3) Under the above circumstances, SetBootOrderFromQemu() removes most of
the boot options produced by (2). Erasing boot options is slow.
Introduce ConnectDevicesFromQemu() as a replacement for (1): only connect
devices that the QEMU user actually wants to boot off of.
(There's a slight loss of compatibility when a platform switches from
EfiBootManagerConnectAll() to ConnectDevicesFromQemu().
EfiBootManagerConnectAll() may produce UEFI device paths that are unknown
to QemuBootOrderLib (that is, for neither PCI- nor virtio-mmio-based
devices). The BootOrderComplete() function lets such unmatched boot
options survive at the end of the boot order. With
ConnectDevicesFromQemu(), these options will not be auto-generated in the
first place. They may still be produced by other means.
SetBootOrderFromQemu() is not modified in any way; reordering+filtering
boot options remains a separate task.)

The "/MAC(" suffix of the translated UEFI devpath prefix is unnecessary
for matching, because the virtio-mmio base address in VenHwString is
unique anyway. Furthermore, the partial string "MAC(" cannot be processed
by ConvertTextToDevicePath(), which will become relevant later in this
series. Remove "/MAC(".
While at it, remove a bogus comment on PCI.
