Laszlo Ersek 5f0f5e90ae ArmVirtPkg/FdtPL011SerialPortLib: call PL011UartLib in all SerialPortLib APIs
With the SerialDxe change in commit 4cf3f37c87 ("MdeModulePkg SerialDxe:
Process timeout consistently in SerialRead", 2017-07-18), setting
EFI_SERIAL_INPUT_BUFFER_EMPTY in the "Control" output parameter, in the
GetControl() SerialPortLib function, is no longer a "small optimization".
Namely, due to the SerialDxe change, the GetOneKeyFromSerial() call in
TerminalDxe's TerminalConInTimerHandler() can take very long if the input
queue is empty, even if GetOneKeyFromSerial()'s return value causes the
loop to be exited right after, in the first iteration.

This issue causes a boot hang in ArmVirtQemu: with the input queue empty,
TerminalConInTimerHandler() takes so long to return that, by the time it
returns, there's another execution queued already (due to the associated
timer event being signaled meanwhile). The boot process is stuck in the
timer event handler.

Therefore even the first GetOneKeyFromSerial() iteration must be prevented
in TerminalConInTimerHandler() if the input queue is empty, and that
requires implementing GetControl() for real.

Implement the SetAttributes(), SetControl() and GetControl() APIs (of
SerialPortExtLib origin) in FdtPL011SerialPortLib with calls to matching
PL011UartLib functions. This follows the example of
"ArmPlatformPkg/Library/PL011SerialPortLib" and also matches Star's
original idea under [1].

The patch can be considered a continuation of commit ad7f6bc2e1
("ArmVirtPkg: Use SerialDxe in MdeModulePkg instead of EmbeddedPkg",
2015-11-26), based on the mailing list threads [1] [2] [3].

Ard Biesheuvel 7b1dc6c569 ArmVirtPkg: switch to generic ResetSystemRuntimeDxe
For obscure reasons, ARM platforms use a different implementation of
the ResetSystem() runtime service call than other platforms. So let's
switch all ArmVirtPkg platforms to the generic version instead.

Given that all platforms use an implementation of EfiResetSystemLib [as
consumed by the ResetRuntimeDxe in EmbeddedPkg that we are replacing]
which is unlikely to be depended upon by out of tree platforms, let's
simply modify this library into an implementation of ResetSystemLib
instead [which is what the generic driver in MdeModulePkg consumes]

This does mean we need to update all clients at the same time, which
is why all changes are part of the same patch.

As before, warm reset and platform specific reset are mapped onto
cold reset (which is the only thing PSCI implements, at least the
version we depend on). The new library function EnterS3WithImmediateWake()
is left unimplemented, as permitted by the ResetSystemLib library class.

Ard Biesheuvel 83ae7589b0 ArmVirtPkg/PlatformPeiLib: honor DT node 'status' property
In some cases, (e.g., when running QEMU with TrustZone emulation), the
DT may contain DT nodes whose status is set to 'secure'. Similarly, the
status may be set to 'disabled' if the consumer of the DT image is
expected to treat it as if it weren't there.

So check whether a 'status' property is present, and if so, ignore the
node if the status is not 'okay'.

Laszlo Ersek e8ae381f60 ArmVirtPkg/QemuFwCfgLib: use DMA for QemuFwCfgWriteBytes() if available
We use the "InternalQemuFwCfgReadBytes" static function pointer to
dispatch the reading of fw_cfg bytes between MMIO and DMA. This pointer is
initialized to MMIO, and we set it to DMA in the library constructor if
DMA is available.

Unlike the above, we write fw_cfg bytes only with MMIO at the moment.
Extend the write functionality so that it follows the read pattern:
- introduce the new function typedef WRITE_BYTES_FUNCTION,
- extract the current (MMIO-only) write internals from
  QemuFwCfgWriteBytes() to MmioWriteBytes(),
- provide a DMA-based implementation in DmaWriteBytes() -- a thin wrapper
  around DmaTransferBytes(),
- set the new static function pointer "InternalQemuFwCfgWriteBytes"
  according to the DMA feature provided by QEMU,
- In QemuFwCfgWriteBytes(), call the best available method through
  "InternalQemuFwCfgWriteBytes".

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.

this case, which means IoTranslation is never referenced *unless* it has
been assigned. So simply set IoTranslation to zero to help the compiler.

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.

Laszlo Ersek efadd41590 ArmVirtPkg/PlatformBootManagerLib: Postpone the shell registration
This patch ports Gary's OvmfPkg commit 14b2ebc30c to ArmVirtPkg.

Turns out Gary's argument in 14b2ebc30c is not only valid for Xen. The
same situation arises with QEMU if:
- the user specifies no boot order via fw_cfg at all (so QemuBootOrderLib
  won't touch the boot order), and
- the varstore file has just been created from the varstore template.

In this case the user is dropped to the UEFI shell (because the shell is
registered earlier than all the auto-generated options), which is likely
not what the user wants.

Laszlo Ersek 2c8805bc95 ArmVirtPkg/PlatformBootManagerLib: rebase boot logo display to BootLogoLib
In the course of porting ArmVirtPkg to the MdeModulePkg BDS, commit
1f73aef50c

  ArmVirtPkg/PlatformBootManagerLib: add EnableQuietBoot & DisableQuietBoot

open-coded the EnableQuietBoot() function (and its dependencies / friends)
from IntelFrameworkModulePkg BDS.

This code duplication can be avoided; the functionality is available from
the following three libraries in MdeModulePkg:

- BootLogoLib: provides the BootLogoEnableLogo() function. It does not
  provide the internal ConvertBmpToGopBlt() function -- that one is
  delegated to ImageDecoderLib (function DecodeImage()).

- ImageDecoderLib: a general library that registers decoder plugins for
  specific image formats, and provides the generic DecodeImage() on top.

- BmpImageDecoderLib: one of said decoder plugins, for handling BMP images
  (which is the format of our logo).

In this patch, we revert 1f73aef50c, and atomically incorporate the
above libraries. This is inspired by Nt32Pkg commit 859e75c4fc42:

  Nt32Pkg: Use BootLogoLib for logo and progress bar drawing.

Laszlo Ersek afa456de25 ArmVirtPkg/PlatformBootManagerLib: rebase boot order manipulation
QemuBootOrderLib can only filter out and reorder boot options; it cannot
create boot options. It relies on Platform BDS to auto-generate all
possible boot options first (for example, for new virtual devices that
have been configured since the last run of the virtual machine). Then it
will decide, case-by-case, whether each of those auto-generated boot
options should be preserved (and at what position), or removed.

Thus far, the only implementation of SetBootOrderFromQemu(), used in
connection with IntelFrameworkModulePkg BDS, has expected said complete
boot option list as an input parameter:

BdsEntry()                         [IntelFrameworkModulePkg/Universal/BdsDxe/BdsEntry.c]
  // create empty list
  InitializeListHead (
    &BootOptionList
    )

  PlatformBdsPolicyBehavior(       [ArmVirtPkg/Library/PlatformIntelBdsLib/IntelBdsPlatform.c]
    BootOptionList
    )

    BdsLibConnectAll()
    BdsLibEnumerateAllBootOption(
      BootOptionList
      )

    // at this point, BootOptionList starts with the preexistent boot
    // options, and ends with the auto-generated options

    SetBootOrderFromQemu(          [OvmfPkg/Library/QemuBootOrderLib/QemuBootOrderLib.c]
      BootOptionList
      )

      // write out changed boot order to UEFI variables

    // The "BootOrder" variable may have changed. Refresh BootOptionList
    // from it, and return it to BdsEntry().

With MdeModulePkg BDS, a BootOptionList is not propagated from BdsEntry()
to SetBootOrderFromQemu() and back. All processing is based directly on
the underlying "BootOrder" and "Boot####" variables.

In OvmfPkg, commit d27ec22d11 introduced a new instance of
QemuBootOrderLib, called QemuNewBootOrderLib. It is based on
UefiBootManagerLib, and rather than taking a complete BootOptionList as a
parameter, it expects that the "BootOrder" and "Boot####" variables are
complete in the above sense.

Rebase the boot order manipulation to UefiBootManagerLib and
QemuNewBootOrderLib, while keeping the requirement satisfied, like this:

BdsEntry()                               [MdeModulePkg/Universal/BdsDxe/BdsEntry.c]
  PlatformBootManagerAfterConsole()      [ArmVirtPkg/Library/PlatformBootManagerLib/PlatformBm.c]
    EfiBootManagerConnectAll()
    EfiBootManagerRefreshAllBootOption()

    // at this point all auto-generated options exist at the end of
    // "BootOrder"

    SetBootOrderFromQemu()               [OvmfPkg/Library/QemuNewBootOrderLib/QemuBootOrderLib.c]

      // read boot options from "BootOrder" and "Boot####", then
      // manipulate them

This patch parallels OvmfPkg commit 04fe914ba5.

Once the USE_OLD_BDS fallback is removed from OvmfPkg, the parameter list
of the SetBootOrderFromQemu() prototype can be updated to VOID.

Laszlo Ersek e2a193b733 ArmVirtPkg/PlatformBootManagerLib: init console vars in BeforeConsole()
With IntelFrameworkModulePkg BDS, the platform code is responsible for
updating console variables (e.g., with BdsLibUpdateConsoleVariable()), and
then connecting them (e.g., with BdsLibConnectAllDefaultConsoles()). This
is usually (although not necessarily) done in PlatformBdsPolicyBehavior().

With MdeModulePkg BDS, the platform is responsible for updating the
console variables in PlatformBootManagerBeforeConsole(). When that
function returns, BdsEntry() will automatically connect the consoles; the
platform is not responsible for the connection.

Thus, move the console variable massaging from the beginning of

BdsLibConnectAllDefaultConsoles() call.

This patch parallels OvmfPkg commit e9e9ad644f.
