Move the TryRunningQemuKernel() call back to its original place. This
improves the UEFI boot time for VMs that have "-kernel", many disks or
NICs, and no "bootindex" properties. A well-known example is
guestfish/libguestfs.
For more info on the TryRunningQemuKernel() location, see the following

The PrePi code we inherited from ArmPlatformPkg contains a rather
obscure optimization, where entry points of the PE/COFF and LZMA
handling routines are recorded in special HOBs, allowing DXE core
to call into that code directly rather than carry its own copy of
these libraries.
Given that no ArmVirtPkg platforms actually include the library
resolutions* that take advantage of these optimizations, let's not
bother with them, and remove the associated code.

The QemuVirtMemInfoLib ArmVirtMemInfoLib implementation created for
ArmVirtQemuKernel does exactly what we need for ArmVirtQemu, the only
difference being that the latter is PrePeiCore based, and so it uses
a different method to ensure that PcdSystemMemorySize is set when
ArmVirtGetMemoryMap() is called.
On ArmVirtQemu, we currently abuse the implied ordering guarantees
provided by ArmPlatformLib, by implementing this as follows:
ArmPlatformPkg/MemoryInitPei/MemoryInitPeim.inf [ArmVirtPkg/ArmVirtQemu.dsc]
InitializeMemory() [ArmPlatformPkg/MemoryInitPei/MemoryInitPeim.c]
ArmPlatformInitializeSystemMemory() [ArmVirtPkg/Library/ArmVirtPlatformLib/Virt.c]
//
// set PcdSystemMemorySize from the DT
//
MemoryPeim() [ArmVirtPkg/Library/ArmVirtMemoryInitPeiLib/ArmVirtMemoryInitPeiLib.c]
InitMmu() [ArmVirtPkg/Library/ArmVirtMemoryInitPeiLib/ArmVirtMemoryInitPeiLib.c]
ArmPlatformGetVirtualMemoryMap() [ArmVirtPkg/Library/ArmVirtPlatformLib/VirtMem.c]
//
// consume PcdSystemMemorySize
//
Given that we are trying to get rid of ArmPlatformLib, or at least remove
some of these API functions that are never used for their original purpose
by any platforms, we need to move the PCD assignment elsewhere.
So create a PEIM-only version of QemuVirtMemInfoLib especially for
ArmVirtQemu, and add the PCD assignment code to its constructor.

- remove support for uncached DRAM mappings
- replace EFI_D_xxx with DEBUG_xxx throughout
- use a temp variable to hold the top of the physical address space
- use AllocatePool () instead of AllocatePages (), given that we use

The VariableRuntimeDxe driver may use CopyMem () on NOR flash regions,
assuming such regions always have full memory semantics. Given that
those regions cannot be mapped as ordinary memory on ARM (due to the
fact that the NOR flash requires device semantics while in write mode)
this prevents us from using BaseMemoryLibOptDxe in VariableRuntimeDxe,
since it may use unaligned accesses and/or DC ZVA instructions, both
of which are incompatible with mappings using device semantics.
Note that there is no way we can work around this by changing the
mapping type between 'memory' and 'device' when switching from read to
write mode and back, because the runtime mapping is created by the OS,
and cannot be changed at will.
So let's just switch to the unaccelerated version of BaseMemoryLib which
does not have the same problem.

One of the reasons for introducing virtio-gpu support to OvmfPkg and
ArmVirtpkg was the fact that under KVM virtualization on ARM, the
legacy VGA cannot be used reliably. This is due to an implementation
detail of QEMU+KVM, which remaps cached host memory into the guest
address space as a framebuffer behind a PCI BAR. Given that the purpose
of a memory mapped framebuffer is its side effects, such BARs should
never be mapped cacheable in the guest, and the mismatched attributes
between host and guest result in a loss of coherency, visible as
corruption in the framebuffer image.
This issue does not occur under TCG emulation, nor did we expect it to
actually bring down the guest under KVM, and so it was deemed harmless
to keep support for the VGA device as well. However, as it turns out,
the fact that the framebuffer BAR is mapped using device semantics by
default may result in unalignment faults when we use the ordinary string
copy routines on the contents. In theory, we could work around this by
remapping the BAR as write combining, but it appears the generic PCI
bus driver does not actually implement this.
So let's remove the QemuVideoDxe driver altogether. This may result
in loss of functionality for use cases that rely on the framebuffer
to be directly addressable (such as EFIFB), but given that this never
worked reliably under KVM in the first place, let's not let that stop
us from dropping support for it.

With the SerialDxe change in commit 4cf3f37c87ba ("MdeModulePkg SerialDxe:
Process timeout consistently in SerialRead", 2017-07-18), setting
EFI_SERIAL_INPUT_BUFFER_EMPTY in the "Control" output parameter, in the
GetControl() SerialPortLib function, is no longer a "small optimization".
Namely, due to the SerialDxe change, the GetOneKeyFromSerial() call in
TerminalDxe's TerminalConInTimerHandler() can take very long if the input
queue is empty, even if GetOneKeyFromSerial()'s return value causes the
loop to be exited right after, in the first iteration.
This issue causes a boot hang in ArmVirtQemu: with the input queue empty,
TerminalConInTimerHandler() takes so long to return that, by the time it
returns, there's another execution queued already (due to the associated
timer event being signaled meanwhile). The boot process is stuck in the
timer event handler.
Therefore even the first GetOneKeyFromSerial() iteration must be prevented
in TerminalConInTimerHandler() if the input queue is empty, and that
requires implementing GetControl() for real.
Implement the SetAttributes(), SetControl() and GetControl() APIs (of
SerialPortExtLib origin) in FdtPL011SerialPortLib with calls to matching
PL011UartLib functions. This follows the example of
"ArmPlatformPkg/Library/PL011SerialPortLib" and also matches Star's
original idea under [1].
The patch can be considered a continuation of commit ad7f6bc2e116
("ArmVirtPkg: Use SerialDxe in MdeModulePkg instead of EmbeddedPkg",
2015-11-26), based on the mailing list threads [1] [2] [3].

Commit 7b1dc6c569a 'ArmVirtPkg: switch to generic ResetSystemRuntimeDxe'
replaced all references in ArmVirtPkg to the deprecated ResetRuntimeDxe
from EmbeddedPkg with the well maintained generic alternative that lives
in MdeModulePkg.
However, as it turns out, the generic driver has a dependency on the
library class ReportStatusCodeLib, whose default resolution is an
implementation that is not safe for use at runtime, resulting in crashes
when trying to invoke it from the OS.
Since we have no use for status codes in any of the ArmVirtPkg
platforms, let's replace all resolutions with a common one to the NULL
implementation.

For obscure reasons, ARM platforms use a different implementation of
the ResetSystem() runtime service call than other platforms. So let's
switch all ArmVirtPkg platforms to the generic version instead.
Given that all platforms use an implementation of EfiResetSystemLib [as
consumed by the ResetRuntimeDxe in EmbeddedPkg that we are replacing]
which is unlikely to be depended upon by out of tree platforms, let's
simply modify this library into an implementation of ResetSystemLib
instead [which is what the generic driver in MdeModulePkg consumes]
This does mean we need to update all clients at the same time, which
is why all changes are part of the same patch.
As before, warm reset and platform specific reset are mapped onto
cold reset (which is the only thing PSCI implements, at least the
version we depend on). The new library function EnterS3WithImmediateWake()
is left unimplemented, as permitted by the ResetSystemLib library class.

Include XenPlatformHasAcpiDtDxe and PlatformHasAcpiDtDxe in the 32-bit
builds too.
Please see https://bugzilla.tianocore.org/show_bug.cgi?id=524
why it is needed. With this patch my arm uefi VM boots.

Remove the library class resolution for ARM's BdsLib: no included
module actually depends on it, and it will be removed shortly.

Given the agreement on the edk2-devel regarding the fact that the
notion whether or not a 'platform has ACPI' is a universal one, move
the PlatformHasAcpi GUID to MdeModulePkg.

The relocatable build of ArmVirtQemuKernel is designed to be executed
from RAM, and contains some scratch memory at the start of the image
to use as a stack very early on, and to preserve the DTB image received
from QEMU while it discovers and initializes memory.
It turns out that 8 KB is a bit on the small side here, especially when
executing with secure world emulation enabled, in which case there are
additional nodes present.
So increase the slack space to 32 KB.
While at it, remove a stale Xen reference that was copy/pasted when this
file was created.

In some cases, (e.g., when running QEMU with TrustZone emulation), the
DT may contain DT nodes whose status is set to 'secure'. Similarly, the
status may be set to 'disabled' if the consumer of the DT image is
expected to treat it as if it weren't there.
So check whether a 'status' property is present, and if so, ignore the
node if the status is not 'okay'.
