A DMA-like transfer interface has recently been implemented in QEMU for
fw-cfg. For ARM and AARCH64 virtual machines, the binding prescribes a new
8-byte wide register at offset 0x10 in the register block. Make VirtFdtDxe
expose this register if it is present.
Please see "docs/specs/fw_cfg.txt" in the QEMU tree for more information.

When MdeModulePkg/Universal/SmbiosDxe is instructed to compose & install
an SMBIOS 3.0 entry point, it keys the Docrev (specification document
revision) field of that structure off of PcdSmbiosDocRev. An upcoming
OvmfPkg patch will have OvmfPkg/Library/SmbiosVersionLib set this PCD
dynamically. Because we use that driver in the ArmVirtQemu.dsc platform,
we must provide a default for the dynamic PCD.

This reverts git commit d2733aa9 (SVN r18042), because it is empty now.
The original problem:
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.
should be hereafter solved similarly to how
OvmfPkg/Library/SmbiosVersionLib is plugged into
MdeModulePkg/Universal/SmbiosDxe now (originally suggested by Jordan
Justen <jordan.l.justen@intel.com>).

This patch de-duplicates the logic added in commit
ArmVirtPkg: QemuFwCfgToPcdDxe: set SMBIOS entry point version
dynamically
(git c98da334, SVN r18043) by hooking DetectSmbiosVersionLib into
SmbiosDxe.
Although said commit was supposed to work with SMBIOS 3.0 payloads from
QEMU, in practice that never worked, because the size / signature checks
in SmbiosVersionInitialization() would always fail, due to the SMBIOS 3.0
entry point being structurally different. Therefore this patch doesn't
regress ArmVirtPkg.

The ARM build still needs an intermediate loader to boot Linux,
since ARM/Linux has no builtin UEFI boot stub (yet).
So add the LinuxLoader UEFI application to the FV, and enable
the FvSimpleFileSystemDxe driver so that we can invoke the
Linux loader from the shell, e.g.,
Shell> linuxloader fs2:zImage -c console=ttyAMA0

ARM BDS support in ArmVirtQemu has been broken since SVN r17969
("ArmPkg/BdsLib: Remove Linux loader from BdsLib") dated July 14th.
Instead of fixing this, let's get rid of the ARM BDS and LinuxLoader
altogether: they violate both the UEFI spec and the arm64 Linux boot
protocol, and lack the level of integration with the QEMU command
line that the Intel BDS has when running under ArmVirtPkg or OvmfPkg.

(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
flag, TTYTERM or VT100.
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
controller operation.
