The relations between T0SZ, the number of translation levels and the
size/alignment of the root table can be expressed in simple arithmetic
expressions, so get rid of the lookup table.
Note that this disregards the fact that the maximum value of T0SZ is
39 not 42 (as one would expect for the smallest VA size using 2 levels)
but since this corresponds to a VA size of 32 MB and 4 MB, respectively,
neither of which are sufficient to run UEFI, we can safely ignore the
distinction.

ArmPlatformPkg/NorFlashDxe: use strictly aligned CopyMem()
The UEFI spec stipulates that unaligned accesses should be enabled
on CPUs that support them, which means all of them, given that we
no longer support pre-v7 ARM cores, and the AARCH64 bindings mandate
support for unaligned accesses unconditionally.
This means that one should not assume that CopyMem () is safe to call
on regions that may be mapped using device attributes, which is the
case for the NOR flash. Since we have no control over the mappings when
running under the OS, and given that write accesses require device
mappings, we should not call CopyMem () in the read path either, but
use our own implementation that is guaranteed to take alignment into
account.

ShellPkg/UefiHandleParsingLib: fix retval for empty child controller array
The ParseHandleDatabaseForChildControllers() function intends to work like
this:
(1) It allocates a "HandleBufferForReturn" local array that's guaranteed
to be big enough for all found handles,
(2) it collects the handles, both counting them in the (mandatory)
"MatchingHandleCount" output parameter, and saving them in the local
"HandleBufferForReturn" array,
(3) if the caller is not interested in the actual handles, then
"HandleBufferForReturn" is released,
(4) if the caller is interested in the handles, and we've found some, then
"HandleBufferForReturn" is passed out through the
"MatchingHandleBuffer" output parameter,
(5) if the caller is interested in the actual handles, but we've found
none, then the "MatchingHandleBuffer" output parameter is set to NULL.
The ASSERT() at the end of the function makes this clear, but the
implementation does not conform to (5). Fix it.

According to PCI spec the next AER capability is relative to
the beginning of PCI configuration space. Hence substract the

For historical reasons, the files under ArmLib are split up into 'common'
files under Common/, containing common C files as well as AArch64 and Arm
specific asm files, and ArmV7 and AArch64 files under ArmV7/ and AArch64/,
respectively. This presumably dates back to the time when ArmLib supported
different revisions of the 32-bit architecture (i.e., pre-V7)
Since the PI spec requires V7 or later, we can simplify this to Arm/ and
AArch64, which aligns ArmLib with the majority of other modules that carry
ARM or AArch64 specific code.
So move the files around so that shared files live at the same level as
ArmBaseLib.inf, and ARM/AArch64 specific files live in Arm/ or AArch64/,
respectively.
ArmPlatformPkg: remove EFI_MEMORY_UC attribute from normal memory
On ARM systems, 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.
Similarly, DC ZVA instructions are only supported on normal memory, not
device memory.
So remove the EFI_MEMORY_UC attribute that we set by default on system RAM.
If any region requires this attribute, it is up to the driver to set this
attribute, and to ensure that no offending operations are performed on it.
ArmVirtPkg: restrict mapping attributes of normal memory to EFI_MEMORY_WB
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.

OvmfPkg/QemuBootOrderLib: drop too strict "/HD(" suffix from vblk prefix
Translating QEMU's virtio-block OpenFirmware device path to a UEFI device
path prefix was one of the earliest case handled in QemuBootOrderLib. At
that time, I terminated the translation output (the UEFI devpath prefix)
with a "/HD(" suffix.
The intent was for the translation to prefix-match only boot options with
HD() device path nodes in them, that is, no auto-generated "device level"
boot options. This was motivated by prioritizing specific boot options
created by OS installers over auto-generated "device level" options.
However, practice has shown that:
- OS installers place their installed boot options first in the boot order
anyway,
- other device types (SATA disks, virtio-scsi disks), where "/HD(" is not
appended, work just fine,
- requiring "/HD(" actually causes problems: after the OS-installed
specific boot option has been lost (or purposely removed), the
auto-generated "device level" boot option does the right thing (see the
Default Boot Behavior under
<http://blog.uncooperative.org/blog/2014/02/06/the-efi-system-partition/>).
The "/HD(" requirement causes such boot options to be dropped, which
prevents "fallback.efi" from running.
Relax the matching by removing the "/HD(" suffix from the translated
prefix.
ArmPkg/DefaultExceptionHandlerLib AARCH64: add minimal backtrace to crash dump

ArmVirtPkg/PciHostBridgeDxe: don't set linux,pci-probe-only DT property
Setting the linux,pci-probe-only was intended to align OSes booting via
DT with OSes booting via ACPI in the way they honor the PCI configuration
performed by the firmware. However, ACPI on arm64 does not currently honor
the firmware's PCI configuration, and the linux,pci-probe-only completely
prevents any PCI reconfiguration from occurring under the OS, including
what is needed to support PCI hotplug.
Since the primary use case was OS access to the GOP framebuffer (which
breaks when the framebuffer BAR is moved when the OS reconfigures the
PCI), we can undo this change now that ArmVirtQemu has moved to a GOP
implementation that does not expose a raw framebuffer in the first place.
This effectively reverts commit 8b816c624dd4 ("ArmVirtPkg/VirtFdtDxe: set
/chosen/linux,pci-probe-only to 1 in DTB")

MdeModulePkg/EbcDxe AARCH64: simplify interpreter entry point thunks
The prototypes of EbcInterpret() and ExecuteEbcImageEntryPoint() are
private to the AARCH64 implementation of EbcDxe, so we can shuffle
the arguments around a bit and make the assembler thunking glue a lot
simpler.
For ExecuteEbcImageEntryPoint(), this involves passing the EntryPoint
argument as the third parameter, rather than the first, which allows
us to do a tail call. For EbcInterpret(), instead of copying each
argument beyond #8 from one native stack frame to the next (before
another copy is made into the VM stack), pass a pointer to the
argument stack.
