The OFW device path that QEMU exports in the "bootorder" fw_cfg file, for
a device that is plugged into the main PCI root bus, is:
/pci@i0cf8/...
Whereas the same device plugged into the N'th extra root bus results in:
/pci@i0cf8,N/pci-bridge@0/...
(N is in hex.)
Extend TranslatePciOfwNodes() so that it not assume a single PCI root;
instead it parse the extra root bus serial number if present, and resolve
it in the translation to the UEFI devpath fragment.
Note that the "pci-bridge@0" node is a characteristic of QEMU's PXB
device. It reflects the actual emulated PCI hierarchy. We don't parse it
specifically in this patch, because it is automatically handled by the
bridge sequence translator added recently in SVN rev 17385 (git commit
feca17fa4b) -- "OvmfPkg: QemuBootOrderLib: parse OFW device path nodes of
PCI bridges".
The macro EXAMINED_OFW_NODES need not be raised from 6. The longest OFW
device paths that we wish to recognize under this new scheme comprise 5
nodes. The initial "extra root bus" OFW fragment, visible at the top,
takes up 2 nodes, after which the longest device-specific patterns (IDE
disk, IDE CD-ROM, ISA floppy, virtio-scsi disk) take 3 more nodes each.

SeaBIOS requires the OpenFirmware device paths exported in the "bootorder"
fw-cfg file to refer to extra (PXB) root buses by their relative positions
(in increasing bus number order) rather than by actual bus numbers.
However, OVMF's PCI host bridge / root bridge driver creates PciRoot(UID)
device path nodes for extra PCI root buses with UID=bus_nr, not position.
(These ACPI devpath UID values must, and do, match the UID values exposed
in QEMU's ACPI payload, generated for PXB root buses.)
Therefore the boot order matching logic will have to map extra root bus
positions to bus numbers. Add a small group of utility functions to help
with that.

QEMU provides an fw_cfg file called "etc/extra-pci-roots", containing a

In this patch we assume that root bus number 0 is always there (same as
before), and scan the rest of the extra root buses, up to and including
255. When an extra root bus is found, we install the PCI root bridge IO
protocol for the previous root bus (which might be bus 0 or just the
previous extra root bus).
The root bridge protocol created thus will report the available bus number
range
[own bus number, next extra root bus number - 1]
The LHS of this interval will be used for the root bus's own number, and
the rest of the interval (which might encompass 0 additional elements too)
can be used by the PCI bus driver to assign subordinate bus numbers from.
(Subordinate buses are provided by PCI bridges that hang off the root bus
in question.)
For MMIO and IO space allocation, all the root buses share the original
[0x8000_0000, 0xFFFF_FFFF] and [0x0, 0xFFFF] ranges, respectively.

On output, the EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Configuration() function
produces a pointer to a buffer of ACPI 2.0 resource descriptors:
Resources A pointer to the ACPI 2.0 resource descriptors that describe
the current configuration of this PCI root bridge. The
storage for the ACPI 2.0 resource descriptors is allocated by
this function. The caller must treat the return buffer as
read-only data, and the buffer must not be freed by the
caller.
PciHostBridgeDxe currently provides this buffer in a structure with static
storage duration. If multiple root bridges existed in parallel, the
pointers returned by their Configuration() methods would point to the same
static storage. A later Configuration() call would overwrite the storage
pointed out by an earlier Configuration() call (which was possibly made
for a different, but still alive, root bridge.)
Fix this problem by embedding the configuration buffer in
PCI_ROOT_BRIDGE_INSTANCE.
While we're at it, correct some typos (Desp -> Desc), spell out a missing
pack(1) pragma, and improve formatting.

Currently we define a device path for each root bridge statically (for all
one of them). Since we'll want to create a dynamic number of root bridges,
replace the static device paths with a common template, embed the actual
device path into the private root bridge structure, and distinguish the
device paths from each other in the UID field (as required by ACPI).

The entry point function of this driver, InitializePciHostBridge(), and
the static storage duration objects it relies on, are speculatively
generic -- they nominally support more than one host bridges, but (a) the
code hardwires the number of host bridges as 1, (b) it's very unlikely
that we'd ever like to raise that number (especially by open-coding it).
So let's just remove the the nominal support, and simplify the code.

The ASSERT() in SetPciIntLine() assumes that Device 0 on "the" root bus
corresponds to the PCI host bridge (00:00). This used to be true, but
because we're going to have extra root buses (with nonzero bus numbers),
soon this assumption may no longer hold. Check for the zero root bus
number explicitly.

Instead of using a NULL implementation of ArmPlatformSysConfigLib for
DXE_RUNTIME_DRIVER modules, which prevents them from accessing system
control registers even at boot time, use the new implementation that
only switches into a non-functional mode at runtime, and operates as
before otherwise.

This adds a ArmPlatformSysConfigLib implementation that is usable by
DXE_RUNTIME_DRIVER modules. Since the system registers that this library
encapsulates are not usable at runtime, this driver allows access to
those registers only at boot time.

Revise some errors which may lead NULL pointer be dereferenced:
* DnsDhcp.c: Paralist may be used without any initialized
* DnsHeader and RcvString may be null but be dereferenced
* HttpDriver.c: revise an if judgment
* HttpImpl.c: add a judgment to avoid null dereferenced

The FileReserved variable in QemuFwCfgFindFile() is only used to skip
over the reserved field in file headers, which causes newer versions of
GCC to flag it with a "variable set but not used" warning (which is normally
not visible since as of right now these warnings are supressed). It's true
that the value read into FileReserved is never used, but this is
intentional. This patch adds a do-nothing reference to silence the
warning.

System may break during time based AuthVariable update, causing certdb inconsistent. 2 ways are used to ensure update atomic.
1. Delete cert in certdb after variable is deleted
2. Clean up certdb on variable initialization
