Laszlo Ersek 5b54c92a65 ArmVirtPkg: undo bogus component name and driver diagnostics disablement
The entry point function of any UEFI_DRIVER that conforms to the UEFI
driver model must install an instance of the EFI_DRIVER_BINDING_PROTOCOL
on the image handle. Beyond that, the following protocols are optional:

- EFI_COMPONENT_NAME_PROTOCOL
- EFI_COMPONENT_NAME2_PROTOCOL
- EFI_DRIVER_CONFIGURATION_PROTOCOL
- EFI_DRIVER_CONFIGURATION2_PROTOCOL
- EFI_DRIVER_DIAGNOSTICS_PROTOCOL
- EFI_DRIVER_DIAGNOSTICS2_PROTOCOL

The UefiLib functions

- EfiLibInstallAllDriverProtocols()
- EfiLibInstallAllDriverProtocols2()
- EfiLibInstallDriverBindingComponentName2()

are convenience helpers for such UEFI_DRIVERs. They simplify the
installation of the above protocols.

The UefiLib instance in "MdePkg/Library/UefiLib/UefiDriverModel.c" allows
platforms to control these functions through the MdePkg feature PCDs

- PcdComponentNameDisable
- PcdComponentName2Disable
- PcdDriverDiagnosticsDisable
- PcdDriverDiagnostics2Disable

If any of these PCDs are set to TRUE, then the helper functions will not
install the corresponding protocol interfaces on the image handle, even if
the driver passes in non-NULL protocol interfaces.

In other words, at build time, a platform can forcibly prevent all drivers
that employ UefiLib from producing these protocols.

In ArmVirtPkg, that's what we've been doing forever, for no reason at all.
This is why we haven't been seeing component and driver names from the DH,
DEVICES, DRIVERS and DEVTREE shell commands, unlike in OvmfPkg.

The default value for all these PCDs is FALSE, in "MdePkg/MdePkg.dec".
Revert ArmVirtPkg to the sane defaults.

This bug dates back to the inception of ArmVirtPkg (called
ArmPlatformPkg/ArmVirtualizationPkg at the time).

Ard Biesheuvel 3c3cf1cd73 ArmVirtPkg: move all platforms to MdePkg/ BaseMemoryLib implementations
The BaseMemoryLibStm implementation under ArmPkg/ is being deprecated,
in favor of the generic versions under MdePkg, now that ARM and AARCH64
support has been added to both the generic C version (BaseMemoryLib) and
the accelerated version (BaseMemoryLibOptDxe). The latter uses unaligned
accesses and special cache maintenance instructions, and can therefore
not be used when the MMU is off.

So move to BaseMemoryLibOptDxe for the DXE phase and later, and to the
generic BaseMemoryLib before that.

Ard Biesheuvel cfc8d51c0c ArmVirtPkg/FdtClientDxe: report address and size cell count directly
The FDT client protocol methods dealing with "reg" properties return
the size of a "reg" element. Currently, we have hardcoded this as '8',
since #address-cells == #size-cells == 2 in most cases. However, for
different values, have a single 'reg' element size is not unambiguous,
since - however unlikely - if #address-cells != #size-cells, we do not
know which is which.

So before adding more methods to the protocol, fix up this oversight.

When parsing the device tree to find the memory node, we are still running
with the MMU off, which means unaligned memory accesses are not allowed.
Since the FDT only mandates 32-bit alignment, 64-bit quantities are not
guaranteed to appear naturally aligned, and so should be accessed using
32-bit accesses instead.

Ard Biesheuvel f2509d6d3e 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.

Ard Biesheuvel 29589acf10 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 8b816c624d ("ArmVirtPkg/VirtFdtDxe: set
/chosen/linux,pci-probe-only to 1 in DTB")

Ard Biesheuvel dfc2838892 ArmVirtPkg: clean up assembly source files
This updates all assembly source files under ArmVirtPkg to mark
exported functions as ASM_FUNC(), which puts them in a separate
section, allowing the linker to prune code that is left unused.

At the same time, clean up the code to get rid of LoadConstantToReg()
instances involving symbol references, each of which emits an absolute
literal, and hence and entry in the PE/COFF .reloc table.

The ArmVirtPkg platforms that use PrePi have no notion of boot remapped

Ard Biesheuvel 87ee6390cb ArmVirtPkg ARM: make relocatable PrePi users build with CLANG35
The clang developers have made a backward incompatible change to the
command line arguments, and have replaced '-mllvm -arm-use-movt=0'
with '-mno-movt'. This does not matter for most ARM platforms, and
therefore it has been removed from the default CLANG35/ARM CC flags
in patch 1c63516075 ("BaseTools CLANG35: drop problematic use-movt
and save-temps options"), but as it turns out, the relocatable PrePi
implementation used by ArmVirtQemuKernel and ArmVirtXen will fail to
build if it contains MOVT/MOVW pairs, due to the fact that these are
not runtime relocatable under ELF.

Since they are runtime relocatable under PE/COFF, and GenFw does the
right thing when encountering them, selectively controlling their
use is more appropriate than disabling them altogether. Therefore,
this patch adds the -mno-movt argument only for the platforms that
use the relocatable PrePi, and only for the module types that may
be pulled into its build.

In addition, switch to the SEC type version of ArmLib, so that
the relocatable PrePi only depends on BASE and SEC type libraries.

Ard Biesheuvel d54e2d6c1e ArmVirtPkg/ArmVirtPrePiUniCoreRelocatable: deal with relaxed XIP alignment
Commit b89919ee8f ("BaseTools AARCH64: override XIP module linker
alignment to 32 bytes") updated the various AARCH64 toolchain definitions
to allow SEC, PEI_CORE and PEIM modules to be built with minimal alignment
requirements even when using the AArch64 small code model which normally
requires 4 KB section alignment.

This involves conversion of ADRP instructions into ADR instructions, which
can only be done reliably if the ELF and the PE/COFF sections appear at
the same offset modulo 4 KB.

The ArmVirtPrePiUniCoreRelocatable linker script did not yet take this
into account, so update it by starting the .text section at the next
appropriately aligned offset PECOFF_HEADER_SIZE bytes into the image.

Ard Biesheuvel a1b8baccc3 BaseTools GCC: use 'gcc' as the linker command for GCC44 and later
To accommodate upcoming GCCx toolchain versions that require 'gcc' to
be used as the linker in order to support LTO, switch GCC44 and later
(including CLANG35) to a new DLINK build rule that invokes 'gcc' as the
linker instead of 'ld'. Since gcc expects its command line arguments in
a different format, and expects arguments that it needs to pass to the
linker to be prefixed with '-Wl,', this involves changes to most of the
DLINK_FLAGS definitions in tools_def.template, as well as some changes to
module .INF files that set their own linker options.

Ard Biesheuvel ff54bcdf2e ArmVirtPkg/ArmVirtPrePiUniCoreRelocatable: ignore .hash and .note sections
Newer versions of ld automatically emit .gnu.hash and .note.gnu.build-id
sections, which are not listed in the linker script, and will end up
breaking the build with an allocation conflict, e.g.,

  /usr/bin/aarch64-linux-gnu-ld: section .note.gnu.build-id loaded at
    [0000000000000000,0000000000000023] overlaps section .text loaded at
    [0000000000000000,0000000000017dbf]

Since we don't require or care about these sections, update the linker
script so that they are discarded. Note that this involves emitting the
.note.gnu.build-id section into a non-allocatable segment to prevent the
linker from noticing that it is being discarded (and subsequently
complaining about it)

Laszlo Ersek 0e2c6c5529 ArmVirtPkg/PlatformBootManagerLib: remove stale FvFile boot options
(This patch ports OvmfPkg commit 2eb3589860 to ArmVirtPkg. That
functionality was not added to QemuBootOrderLib, because it was (and is)
independent from QEMU and fw_cfg.)

Remove any boot options that point to binaries built into the firmware and
have become stale due to any of the following:
- FvMain's base address or size changed (historical -- see commit
  e191a3114f),
- FvMain's FvNameGuid changed,
- the FILE_GUID of the pointed-to binary changed,
- the referenced binary is no longer built into the firmware.

For example, multiple such "EFI Internal Shell" boot options can coexist.
They technically differ from each other, but may not describe any built-in
shell binary exactly. Such options can accumulate in a varstore over time,
and while they remain generally bootable (thanks to the efforts of
BmGetFileBufferByFvFilePath()), they look bad.

Filter out any stale options.
