Star Zeng efef6ad6d7 MdeModulePkg AcpiTableDxe: Use Rsdt to check against NULL
Some static scan tool may regard CurrentRsdtEntry to be potentially
referenced to NULL pointer if CurrentRsdtEntry == NULL is used in
the right above if condition judgment.

        CopyMem (CurrentRsdtEntry, CurrentRsdtEntry + 1, (*NumberOfTableEntries - Index) * sizeof (UINT32));

It is introduced by commit f9bbb8d9c3.
To avoid it and have same style with
"((Xsdt == NULL) || CurrentTablePointer64 == (UINT64) (UINTN) Table->Table)",
use Rsdt instead of CurrentRsdtEntry to check against NULL.

1. The consumer of Acpi Sdt Protocol may want to use the API after ReadyToLock.

Samer El-Haj-Mahmoud 4f0f2316ed MdeModulePkg: Fix IPv4 double free
Fix a possible ASSERT after NBP finishes loading from a PXE
boot. Ip4Dxe driver calls Ip4Config2SetPolicy which calls
CloseEvent on the Dhcp4Event struct member.  After NBP is
downloaded, it then calls Ip4Config2CleanInstance which calls
CloseEvent again on Dhcp4Event.  This double free can cause an
ASSERT. When the event is closed, set the event pointer to NULL
so the Ip4 code won't call CloseEvent on it again.

Jiaxin Wu 7648748e99 MdeModulePkg: Change the default IPv4 config policy
Git version '3d0a49ad' commit provided a scenario to resolve the
performance issue for IPv4, but it's not workable for IPv6. To
avoid IPv4 and IPv6 inconsistency, we decided to revert that version
fix.

If so, the default policy for Ip4Config2 is Ip4Config2PolicyDhcp,
which results in all NIC ports attempting DHCP. So, this patch is
used to changes the the default IPv4 config policy to
Ip4Config2PolicyStatic and also defer the SetData operation after
Ip4Config2Protocol installed. This update let the other platform
drivers have chance to change the default config data by consume
Ip4Config2Protocol.

Ard Biesheuvel f9bbb8d9c3 MdeModulePkg: AcpiTableDxe: make 4 GB table allocation limit optional
AARCH64 systems never require compatibility with legacy ACPI OSes, and
may not have any 32-bit addressable system RAM. To support ACPI on these
systems, we need to be able to relax the 4 GB allocation restriction.

So add a PCD PcdAcpiExposedTableVersions containing a bitmask describing
which ACPI versions are targeted, and wire it up it up to the memory
allocation calls in AcpiTableDxe/AcpiTableProtocol.c. I.e., if ACPI v1.0b
is not among the supported versions, the memory allocations are not limited
to 4 GB, and only table types that carry 64-bit addresses are emitted.

Note that this will inhibit the publishing of any tables that carry only
32-bit addresses, i.e., RSDPv1, RSDTv1 and RSDTv3.

Laszlo Ersek 31ae446b1a MdeModulePkg: TerminalDxe: select the UART's default receive FIFO depth
The Serial IO protocol instances provided by SerialDxe and consumed by
TerminalDxe come with a Mode.ReceiveFifoDepth=1 default setting, as
required by UEFI 2.5.

Although TerminalDxe calls EFI_SERIAL_IO_PROTOCOL.SetAttributes() in the
TerminalDriverBindingStart() and TerminalConInTimerHandler() functions, it
only does so to change the Mode.Timeout member. Other members of Mode,
including Mode.ReceiveFifoDepth, are preserved.

On some platforms this causes the UART that underlies TerminalDxe not to
have enough room for bursts of scan codes, which translates to broken
parsing of escape sequences, e.g. cursor movement keys.

According to the UEFI spec, passing ReceiveFifoDepth=0 to
EFI_SERIAL_IO_PROTOCOL.SetAttributes() "will use the device's default FIFO
depth". While TerminalDxe could try to configure a receive FIFO depth that
matches the longest escape sequence it wishes to parse, in practice the
device-specific default FIFO depth -- which may well differ from the
spec-mandated SerialIo->Mode.ReceiveFifoDepth=1 default -- seems to work.
Hence let's just set that.

This issue was exposed by SVN r18971 / git commit 921e987b2b
("ArmPlatformPkg: Use SerialDxe in MdeModulePkg instead of EmbeddedPkg").
In that conversion, MdeModulePkg's SerialDxe started to initialize
Mode.ReceiveFifoDepth to 1 (in conformance with the spec), unlike the
prior, non-conformant initialization to 0 in EmbeddedPkg's SerialDxe.

Since TerminalDxe would never change ReceiveFifoDepth from the new default
value 1, and the ArmPlatformPkg/Drivers/PL011Uart library instance,
underlying SerialDxe through SerialPortLib, would obey it too, they would
collectively effect a receive queue depth of 1, rather than the default 16
or 32. This broke cursor keys on the ARM FVP and Juno platforms.

It is the client of EFI_SERIAL_IO_PROTOCOL that is responsible for
modifying the attributes, if the defaults are not appropriate, hence this
patch modifies TerminalDxe.

It also says, about the EFI_SERIAL_IO_MODE.ControlMask member:

  (g) A mask of the Control bits that the device supports. The device must
      always support the Input Buffer Empty control bit.

SerialDxe complies with requirement (b) via hard-coded constants. It
complies with requirements (a), (d), (e) and (f) through PCD defaults (see
MdePkg/MdePkg.dec):

(a) 115,200 baud:
  gEfiMdePkgTokenSpaceGuid.PcdUartDefaultBaudRate|115200|UINT64|0x00000020

(d) no parity:
  # 1 - No Parity.<BR>
  gEfiMdePkgTokenSpaceGuid.PcdUartDefaultParity|1|UINT8|0x00000022

(e) 8 data bits:
  gEfiMdePkgTokenSpaceGuid.PcdUartDefaultDataBits|8|UINT8|0x00000021

(f) 1 stop bit:
  # 1 - One Stop Bit.<BR>
  gEfiMdePkgTokenSpaceGuid.PcdUartDefaultStopBits|1|UINT8|0x00000023

SerialDxe does not comply with requirements (c) and (g). In this patch, we
fix (c), and leave (g) for later.

Yao, Jiewen abad83e6c2 MdeModulePkg: Add MorLockSmm to variable driver.
Microsoft published secure MOR implementation at https://msdn.microsoft.com/en-us/library/windows/hardware/mt270973(v=vs.85).aspx
with revision 2 update. See URL for tech detail.
Previous revision 1 is handled in SecurityPkg\Tcg\ MemoryOverwriteRequestControlLock.
But the VarCheck API can not satisfy revision 2 requirement.
So we decide include MOR lock control into variable driver directly.

This patch add standalone TcgMorLockSmm implementation.
