Ard Biesheuvel c9e5618f84 ArmVirtualizationPkg: Xen: shuffle init order to deal with incoherency
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.

Ard Biesheuvel e1d5299099 ArmVirtualizationPkg: invalidate PEI memory region by VA
This updates ArmVirtualizationMemoryInitPeiLib so that the PEI memory
region, i.e., the region that is used both before and after the MMU
and caches are enabled, is invalidated by virtual address before
enabling the MMU.

This prevents issues where data we modified with the caches and MMU
off may be shadowed by clean cachelines in system caches or in lower
level caches on other CPUs, resulting in the this data to become
invisible once we turn the MMU and caches on.

Ard Biesheuvel d94a48c71a ArmPlatformPkg: do not fulfil MemoryInitPeiLib dependency directly via .c file
MemoryInitPeim short-circuits its MemoryInitPeiLib dependency by including
the .c file directly. This prevents us from having a special implementation
for ArmVirtualizationPkg that performs additional cache maintenance before
enabling the MMU. So instead, make it depend on the library class.

Ard Biesheuvel 15f7a89f77 ArmVirtualizationPkg: make ArmVirtualizationMemoryInitPeiLib the default
This updates ArmVirtualization.dsc.inc to use the MemoryInitPeiLib
implementation for virt targets. The only difference between that one
and the original one is that the original one removes memory from the
available list if it overlaps the FD region (which may be the case when
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.

Laszlo Ersek eee326024e ArmVirtualizationPkg/ArmVirtualizationQemu: include XHCI driver
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.

Laszlo Ersek da1ce6f886 ArmVirtualizationPkg: build UEFI shell from source
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
partly technical (a developer patching the shell can actually see the
results), partly ideological (the nominally built-from-source firmware is
actually built from source). "Security" might be worth a mention too.

The stanza for the [Components.common] section of
"ArmVirtualization.dsc.inc" originates from under OvmfPkg.

Laszlo Ersek 7602900aba ArmVirtualizationPkg: PlatformIntelBdsLib: lack of QEMU kernel is no error
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
stock ArmPlatformPkg version only in the fact that it does not remove
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 is partially motivated by the desire to use PrePi in a virt
environment, and in that configuration, ArmPlatformInitializeSystemMemory()
is never called. But actually, this is a more suitable place anyway.

Ard Biesheuvel ada518b7d6 ArmVirtualizationPkg: allow patchable PCD for device tree base address
To allow a runtime self relocating PrePi instance to discover the base
address of the device tree at runtime, allow the use of a patchable PCD
for gArmVirtualizationTokenSpaceGuid.PcdDeviceTreeInitialBaseAddress.
We will not be using the build time patch tool in this case, but using
a patchable PCD will make the build system aware that its value is not
a compile time constant.

Ard Biesheuvel 967efdcdc3 ArmPkg: allow HYP timer interrupt to be omitted
The DT binding for the ARM generic timer describes the secure,
non-secure, virtual and hypervisor timer interrupts, respectively.
However, under virtualization, only the virtual timer is usable, and
the device tree may omit the hypervisor timer interrupt. (Other timer
interrupts cannot be omitted simply due to the fact that the virtual
timer is listed third)

Laszlo Ersek 60dc18a17c ArmVirtualizationPkg: PlatformIntelBdsLib: detect consoles dynamically
Detect the video displays dynamically, and add them to the console and
error output variables.

Add a short-form, "wild card" USB_CLASS_DEVICE_PATH to the console input
variable, which causes the USB keyboard to be handled automatically.

Add the fixed location serial console to all of the console input, console
output, and error output variables.

This patch enables QEMU users to drop "addr=..." PCI address
specifications from the -device options (or to use whatever addresses they
like). For example, the following works:

  -device VGA \
  \
  -device ich9-usb-ehci1,multifunction=on,id=ehci \
  -device ich9-usb-uhci1,multifunction=on,masterbus=ehci.0,firstport=0 \

Laszlo Ersek ba67a14541 ArmVirtualizationPkg: PlatformIntelBdsLib: remove ties to ARM BDS
In this patch we remove all dependencies on ARM BDS libraries. We also
remove empty and/or unneeded functions, includes, etc.

PlatformIntelBdsLib "goes back to basics" temporarily -- there are no
consoles configured, and it's practically not possible to interact with
the user interface. Bisection remains available in the sense that
"ArmVirtualizationQemu.dsc" continues to build and should boot preexistent
boot options, but user interaction does regress temporarily.

The reason for this is that it's preferable to keep this patch and the
next one separate for readability's sake -- they amount to a rewrite from
scratch.
