Now that GenFw correctly propagates the minimum alignment of the ELF
input sections to the PE/COFF binary, we can simply select 'auto'
alignment in the FDF Rule section instead of tweaking it by hand.
Also add the FIXED FFS attribute to the module types that may execute
in place. This enables a newly added optimization in GenFfs that strips
redundant padding, preventing excessive waste of FV space if the section
alignment is considerable (i.e., 2 KB or 4 KB)

The ACPI .aslc files contain a ReferenceAcpiTable() function whose
sole purpose is to ensure that the table itself does not get optimized
away. However, when using clang, these dummy functions result in a 4 KB
section alignment requirement, which is silly since everything except
the .data section is discarded later anyway.
So instead, make ReferenceAcpiTable a CONST pointer to VOID*. This way,
we still have a .text section, which is mandatory for the PE/COFF
conversion, but no executable code with small model relocations that
impose additional alignment requirements.

Since PrePeiCore's .text section contains an AARCH64 exception
vector table, its 2 KB alignment propagates to other sections as
well. Since this is a SEC module, it should not have any writable
data in the first place, so change some non-const PPI globals to
const. The resulting binary has no .data section at all, which
saves 2 KB in the XIP image.

The current implementation of ArmGicGetSupportedArchRevision ()
that is used by all ARM platforms is entirely stateless (in order
to support being executed from flash) so it needs to interrogate
the hardware for the supported GIC revision upon each invocation.
However, this statelessness is only needed for SEC type modules;
in all other cases, we could easily determine the GIC revision once,
and store the result in a global variable.
In preparation of having separate early and normal versions, this patch
introduces the ArmGicArchLib library class and default implementation,
and moves the existing ArmGicGetSupportedArchRevision () into it.

Note: The reason why the start of the System Memory has not been

The NorFlashDxe uses an explicit 'BEFORE xxx' Depex declaration to
ensure that it is dispatched before VariableRuntimeDxe, and uses the
file GUID of the latter as 'xxx' explicitly to accomplish that.
However, when enabling UEFI Secure Boot, this breaks down since the
authenticated VariableRuntimeDxe is a completely separate driver, with
a different GUID. Also, the hardcoded dependency on gEfiVariableGuid,
which is not used under UEFI Secure Boot, needs to be factored out in
order to allow this driver to be used.
So clone NorFlashDxe.inf into NorFlashAuthenticatedDxe.inf, and fix
up the dependencies so they refer to gEfiAuthenticatedVariableGuid and
SecurityPkg/VariableAuthenticated/RuntimeDxe/VariableRuntimeDxe.inf
instead.

In order to prevent memory corruption issues caused by the fact that,
under virtualization, the guest is incoherent with the hypervisor's view
of memory until it enables its caches and MMU, this patch reshuffles the
init sequence so that the Xen shared memory regions are not touched
before the caches and MMU are enabled.
In addition, the loaded image itself is invalidated by virtual address,
to ensure that any runtime changes (such as the applied relocations) will
not suddenly become invisible once we turn the caches on.

shadowing NOR flash with system RAM). This is never the case for the
Qemu target, which is the only platform affected by this change, since
the Xen target already uses this library explicitly.
This allows us to remove the Xen-specific declaration of this library
dependency. For the Qemu target, this change will not take effect until
after the MemoryInitPeim<->MemoryInitPeiLib dependency resolution is
fixed in a subsequent patch.

The "virt" machine type of qemu-system-(arm|aarch64) had no PCIe support
prior to qemu commit
4ab29b82 arm: Add PCIe host bridge in virt machine
With that commit, the "virt" board acquired the capability to expose an
XHCI controller. Using a USB keyboard as example, the command line options
were
-device nec-usb-xhci -device usb-kbd
However, due to a slight XHCI emulation bug in QEMU -- dating back to
several years earlier -- edk2's XHCI driver would encounter a failed
ASSERT().
This emulation problem has been fixed in QEMU commit
aa685789 xhci: generate a Transfer Event for each Transfer TRB with the
IOC bit set
and now edk2's XHCI driver works well on QEMU's "nec-usb-xhci" device.
Let's enable the driver in ArmVirtualizationQemu, as XHCI emulation is
reportedly more virtualization-friendly than EHCI, consuming less CPU.
(ArmVirtualizationXen is not modified because it includes no USB-related
drivers at all.)
This patch should not regress existing QEMU command lines (ie. expose the
failed ASSERT()) because QEMU's "-device nec-usb-xhci" has never before
resulted in USB devices that worked with edk2 firmware builds, hence users
have never had a reason to add that option.
Now that they learn about XHCI support in ArmVirtualizationQemu by reading
this commit message, they (or their packagers) will also know to update
qemu to aa685789 or later (in practice that means the upcoming 2.3
release), at least if they want to use '-device nec-usb-xhci' with edk2,
for the first time ever.

Including a prebuilt shell executable in the firmware binary is suboptimal
practice, especially given that the source code of the UEFI shell resides
in the same edk2 tree. Benefits of building the shell from source are

actually built from source). "Security" might be worth a mention too.

When the user doesn't pass a kernel with QEMU's "-kernel" switch, the
firmware sees a zero-sized kernel blob via the QemuFwCfgItemKernelSize
key; there's no way to distinguish "no kernel" from "zero sized kernel".
In both cases TryRunningQemuKernel() proceeds as far as gBS->LoadImage(),
which then rejects the zero sized synthetic file with EFI_UNSUPPORTED.
This is known and works fully as expected; however we should rather catch
the much more frequent "no kernel" case earlier, in order to avoid the
EFI_D_ERROR message
TryRunningQemuKernel: LoadImage(): Unsupported
which is arguably meaningless noise for the "no kernel" case.

This implements a MemoryInitPeiLib instance that differs from the

the memory used by the flash device (FD). The reason is that, when using
PrePi, the DXE core is started immediately and never returns so there is
no reason to preserve any of the memory that the flash device occupied
originally, and it is preferable to release is so that the OS loader
can reuse it. This is especially important for the relocatable PrePi
configuration, which is aimed at being launched from a boot loader that
itself adheres to the Linux arm64 boot protocol.

This patch introduces a relocatable PrePi, which can execute
from arbitrary offsets in RAM. This is intendend to be run
from a boot loader which passes a description of the actual
platform in a device tree, for instance.
This module is based on the PrePi implementations residing under
ArmPlatformPkg.

Our primary user QEMU/mach-virt presents us with a FDT blob padded
to 64 KB with plenty of room to set additional properties. However,
in the general case, we should only add properties after making sure
there is enough room available.

Instead of using a dynamic PCD, store the device tree address in a HOB
so that we can also run under a configuration that does not support
dynamic PCDs.
This also adds MemoryAllocationLib to the [LibraryClasses] section of
ArmVirtualizationPlatformLib/ArmVirtualizationPlatformLib.inf, as this
dependency was formerly satisfied transitively through one of the
library dependencies that were dropped.
