Laszlo Ersek 90683caedf ArmVirtPkg/PlatformCI: stick with "ubuntu-18.04" for now
"vm_image: 'ubuntu-latest'" now refers to Ubuntu Focal (20.04LTS), not
Ubuntu Bionic (18.04LTS), according to
<https://github.com/actions/virtual-environments/issues/1816>.

In Focal, the "qemu" package is a dummy package with no dependencies, and
so the actual emulators are not pulled in. Compare:

  https://packages.ubuntu.com/bionic/qemu
  https://packages.ubuntu.com/focal/qemu

This causes CI runs to fail.

It would be best to switch to the "qemu-system" package name, which
continues to depend on the emulators:

  https://packages.ubuntu.com/bionic/qemu-system
  https://packages.ubuntu.com/focal/qemu-system

However, while that package does make the emulators available, the
emulators crash. So for now, stick with the previous Ubuntu environment,
which continues to be supported, per
<https://github.com/actions/virtual-environments/issues/1816>.

from the Kvmtool device tree and updates the
Index and Target register PCDs.

As these PCDs are defined in PcAtChipsetPkg.dec,
this patch updates the CI script to add this

Sami Mujawar 6038e7a2c2 ArmVirtPkg: Support for kvmtool virtual platform
Kvmtool is a virtual machine manager that enables hosting
KVM guests. Kvmtool emulates certain devices like serial
port, RTC, etc. essentially providing a virtual platform.

This patch adds support for kvmtool virtual platform.

Following is a brief description of the firmware
implementation choices:

- Serial Port: 16550 UART
  On some platforms the 16550 UART is interfaced using
  PCI. Therefore, the 16550 Serial port library is
  dependent on the PCI library. The 16550 UART driver
  checks the Device ID represented using the PCD
  gEfiMdeModulePkgTokenSpaceGuid.PcdSerialPciDeviceInfo
  to determine if the UART is behind PCI.
  If the Device ID is 0xFF then the serial 16550 UART
  is not behind PCI.

  On Kvmtool the Serial 16550 UART is not behind PCI,
  and therefore a combination of BasePciLibPciExpress
  and BasePciExpressLib is used to satisfy the PCI
  library dependency.

  The PcdSerialPciDeviceInfo is also set to 0xFF to
  indicate that the Serial 16550 UART is not behind
  PCI. The PCD PcdSerialUseMmio is also set to TRUE
  to indicate MMIO accesses are required for the
  UART registers.

  Additionally two instances of PlatformHookLibs are
  provided EarlyFdt16550SerialPortHookLib and
  Fdt16550SerialPortHookLib to patch the
  PcdSerialRegisterBase so that BaseSerialPortLib16550
  and retrieve the base address of the 16550 UART.

- Dependency order for Flash
  FaultTolerantWriteDxe makes use of PCDs (e.g.
  PcdFlashNvStorageFtwSpareBase64 etc.), which in
  case of kvmtool will be evaluated based on the CFI
  flash base address read from the DT. These variables
  are populated in the NorFlashPlatformLib loaded by
  ArmVeNorFlashDxe.

  This results in a dependency issue with
  FaultTolerantWriteDxe. To resolve this make the
  NorFlashPlatformLib as a library dependency for
  FaultTolerantWriteDxe.

- RTC Controller
  A separate patch updates the MC146818 RTC controller
  driver to support MMIO accesses.
  A KvmtoolRtcFdtClientLib has been introduced to
  extract the base addresses of the RTC controller
  from the platform device tree and map the RTC
  register space as Runtime Memory.

Sami Mujawar a482f08d99 ArmVirtPkg: 16550 UART Platform hook library
The BaseSerialPort16550 library invokes the
PlatformHookSerialPortInitialize() implemented as
part of the PlatformHook library, to perform platform
specific initialization required to enable use of the
16550 device. The BaseSerialPort16550 library uses
the PcdSerialRegisterBase to obtain the base address
of the UART for MMIO operations.

Some VMMs like Kvmtool provide the base address of
the console serial port in the platform device tree.

This patch introduces two instances of the Platform
Hook library:
1. EarlyFdt16550SerialPortHookLib - parses the
   platform device tree to extract the base
   address of the 16550 UART and update the PCD
   PcdSerialRegisterBase.
2. Fdt16550SerialPortHookLib - reads the GUID
   Hob gEarly16550UartBaseAddressGuid (that caches
   the base address of the 16550 UART discovered
   during early stages) and updates the PCD
   PcdSerialRegisterBase.

Note:
  a. The PCD PcdSerialRegisterBase is configured
     as PatchableInModule.
  b. A separate patch introduces a PlatformPeiLib
     that trampolines the 16550 UART base address
     from the Pcd PcdSerialRegisterBase to the
     GUID Hob gEarly16550UartBaseAddressGuid.

Ard Biesheuvel a4a2258a1f ArmVirtPkg/NorFlashQemuLib: disable NOR flash DT nodes upon discovery
Our UEFI guest firmware takes ownership of the emulated NOR flash in
order to support the variable runtime services, and it does not expect
the OS to interfere with the underlying storage directly. So disable
the NOR flash DT nodes as we discover them, in a way similar to how we
disable the PL031 RTC in the device tree when we attach our RTC runtime
driver to it.

Note that this also hides the NOR flash bank that carries the UEFI
executable code, but this is not intended to be updatable from inside
the guest anyway, and if it was, we should use capsule update to do so.
Also, the first -pflash argument that defines the backing for this flash
bank is often issued with the 'readonly' modifier, in order to prevent
any changes whatsoever to be made to the executable firmware image by
the guest.

This issue has become relevant due to the following Linux changes,
which enable the flash driver stack for default build configurations
targetting arm64 and 32-bit ARM.

Ard Biesheuvel b16fd231f6 ArmVirtPkg/PrePi: use standard PeCoff routines for self-relocation
Instead of having a GCC specific routine to perform self-relocation
based on ELF metadata, use the PE/COFF metadata and the existing
PeCoff library routines. This reduces the amount of bespoke assembler
code that is a burden to maintain, and is not portable across the set
of toolchains we support.

This does require some special care, as we have no control over how
the C code references global symbols, so we need to emit these
references from the calling assembler code. Otherwise, they may be
emitted as absolute references, in which case they need to be fixed
up themselves, leading to a circular dependency.

A DEBUG_VERBOSE message is logged on success too, for our QE team's sake.

Laszlo Ersek a5c2ce7cd1 ArmVirtPkg: convert LFs to CRLF
We're going to switch the internal line terminators globally to LF at some
point, but until then, let's use CRLF consistently. Convert source files
with LFs in them to CRLF, using "unix2dos".

"git show -b" prints no code changes for this patch.

(I collected all the file name suffixes in this package, with:

$ git ls-files -- $PACKAGE | rev | cut -f 1 -d . | sort -u | rev

I eliminated those suffixes that didn't stand for text files, then
blanket-converted the rest with unix2dos. Finally, picked up the actual
changes with git-add.)

The CRLF conversion is motivated by "PatchCheck.py".

If a TPM is found, install the gOvmfTpmDiscoveredPpiGuid signalling PPI
that will unlock the dispatch of OvmfPkg's Tcg2ConfigPei. If TPM2
support is enabled in the build but no TPM2 device is found, install the
gPeiTpmInitializationDonePpiGuid PPI, which is normally installed by
Tcg2ConfigPei if no TPM2 is found, but in our case Tcg2ConfigPei will
never run so let's do it here instead.

Laszlo Ersek ae9f12058d ArmVirtPkg/PlatformBootManagerLib: unload image on EFI_SECURITY_VIOLATION
The LoadImage() boot service is a bit unusual in that it allocates
resources in a particular failure case; namely, it produces a valid
"ImageHandle" when it returns EFI_SECURITY_VIOLATION. This is supposed to
happen e.g. when Secure Boot verification fails for the image, but the
platform policy for the particular image origin (such as "fixed media" or
"removable media") is DEFER_EXECUTE_ON_SECURITY_VIOLATION. The return code
allows platform logic to selectively override the verification failure,
and launch the image nonetheless.

ArmVirtPkg/PlatformBootManagerLib does not override EFI_SECURITY_VIOLATION
for the kernel image loaded from fw_cfg -- any LoadImage() error is
considered fatal. When we simply treat EFI_SECURITY_VIOLATION like any
other LoadImage() error, we leak the resources associated with
"KernelImageHandle". From a resource usage perspective,
EFI_SECURITY_VIOLATION must be considered "success", and rolled back.

Implement this rollback, without breaking the proper "nesting" of error
handling jumps and labels.

Ard Biesheuvel 04d9d89b7d ArmVirtPkg/ArmVirtPrePiUniCoreRelocatable: revert to PIE linking
In some cases, the CLANG38 toolchain profile in LTO mode emits GOT
based relocations in spite of our attempts to avoid this, by using
hidden visibility, -Bsymbolic etc.

On AARCH64, we managed to work around this by processing the GOT
based relocations in GenFw. As it turns out, the same issue exists
on 32-bit ARM, but unfortunately, we cannot use a similar trick to
get rid of the GOT entry, and the relocation metadata is insufficient
to locate the GOT entry in the binary.

Note that in this particular case, we are interested in PIE linking
only (i.e., producing a .rela section containing dynamic relocations
that the startup code can process directly), and not in position
independent code generation, and by passing the -pie option to the
linker directly using -Wl,-pie (and dropping -shared), we can coerce
the GOLD linker into doing only the former rather than both when it
performs its LTO code generation.
