Hao Wu ada4a003f9 UefiCpuPkg: Merge StuffRsb.inc files into one in UefiCpuPkg/Include
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1091

Previously, when compiling NASM source files, BaseTools did not support
including files outside of the NASM source file directory. As a result, we
duplicated multiple copies of "StuffRsb.inc" files in UefiCpuPkg. Those
INC files contain the common logic to stuff the Return Stack Buffer and
are identical.

After the fix of BZ 1085:
https://bugzilla.tianocore.org/show_bug.cgi?id=1085
The above support was introduced.

Thus, this commit will merge all the StuffRsb.inc files in UefiCpuPkg into
one file. The merged file will be named 'StuffRsbNasm.inc' and be placed
under folder UefiCpuPkg/Include/.

After commit b3497b, each GenFds run in the same python interpeter, so

Hao Wu d9f1cac51b MdePkg/BaseLib: Introduce new SpeculationBarrier API
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1417

X86 specific BaseLib API AsmLfence() was introduced to address the Spectre
Variant 1 (CVE-2017-5753) issue. The purpose of this API is to insert
barriers to stop speculative execution. However, the API is highly
architecture (X86) specific, and thus should be avoided using across
generic code.

To address this issue, this patch will add a new BaseLib API called
SpeculationBarrier(). Different architectures will have different
implementations for this API.

For IA32 and x64, the implementation of SpeculationBarrier() will
directly call AsmLfence().

For ARM and AARCH64, this patch will add a temporary empty implementation
as a placeholder. We hope experts in ARM can help to contribute the actual
implementation.

For EBC, similar to the ARM and AARCH64 cases, a temporary empty
implementation is added.

Ard Biesheuvel 41203b9ab5 BaseTools/tools_def ARM: use softfloat target for CLANG3x
The 'arm-linux-gnueabihf' target triplet we use for CLANG35 and
CLANG38 specifies a hardfloat target, and so the binaries that are
emitted are annotated as using VFP registers for passing floating
point arguments, even though no VFP is used anywhere in the code.

This works fine as long as we don't try to link against code
that uses software floating point, but combining object files
with different floating point calling conventions is not permitted.

So switch to the softfloat arm-linux-gnueabi triplet instead.
This affects both the name Clang uses when invoking the linker,
and the arguments it passes to it, and we are mostly interested
in the latter (since any version of GNU ld.bfd will do the right
thing as long as it targets EABI ARM)

For native builds, this change has no effect, since the unprefixed
system linker will take priority, and so Clang will pass the right
arguments to whichever linker happens to be the system linker.

For cross builds, the fact that Clang composes the name of the
linker by prefixing '-ld' with the target triplet implies that
users will have to switch to a version of binutils that targets
arm-linux-gnueabi rather than arm-linux-gnueabihf. Note that the
GCCx toolchain targets can use either when building for ARM so this
does not create a need to install two versions of the ARM cross
toolchain. Also, note that all ARM toolchains in the GCC family
are already documented as requiring a toolchain that targets
arm-linux-gnueabi and not arm-linux-gnueabihf.

According to following web page in openssl.org, all security issues

However, the hardware does support the intended usage model, as long

mode involving a handler that is registered by the DXE core and invoked
when the watchdog runs out. In the interrupt handler, we invoke the
notify function if one was registered, before calling the ResetSystem()

The current ArmVirtMemoryInitPeiLib code splits the memory region passed
via PcdSystemMemoryBase/PcdSystemMemorySize in two if the region extends
beyond the MAX_ADDRESS limit. This was introduced for 32-bit ARM, which
may support more than 4 GB of physical address space, but cannot address
all of it via a 1:1 mapping, and a single region that is not mappable
in its entirety is unusable by the PEI core.

AArch64 is in a similar situation now: platforms may support more than
256 TB of physical address space, but only 256 TB is addressable by the
CPU, and so a memory region that extends from below this limit to above
it should be split.

Ard Biesheuvel 1c36f028fa ArmPkg/ArmMmuLib: take MAX_ALLOC_ADDRESS into account
When creating the page tables for the 1:1 mapping, ensure that we don't
attempt to map more than what is architecturally permitted when running
with 4 KB pages, which is 48 bits of VA. This will be reflected in the
value of MAX_ALLOC_ADDRESS once we override it for AArch64, so use that
macro instead of MAX_ADDRESS.

Ard Biesheuvel 67b8f806d2 MdePkg/Base: introduce MAX_ALLOC_ADDRESS
On some architectures, the maximum representable address deviates from
the virtual address range that is accessible by the firmware at boot
time. For instance, on AArch64, UEFI mandates a 4 KB page size, which
limits the address space to 48 bits, while more than that may be
populated on a particular platform, for use by the OS.

So introduce a new macro MAX_ALLOC_ADDRESS, which represent the maximum
address the firmware should take into account when allocating memory
ranges that need to be accessible by the CPU at boot time.

Ard Biesheuvel d05d5f6c85 BaseTools/tools_def ARM: emit PIC veneers
The ARM linker may emit veneers, i.e., trampolines, when ordinary
direct relative branches cannot be used, e.g., for Thumb interworking
or branch targets that are out of range.

Usually, such veneers carry an absolute reference to the branch
target, which is problematic for us, since these absolute references
are not covered by annotations that are visible to GenFw in the
PE/COFF conversion, and so these absolute references are not fixed
up by the PE/COFF loader at runtime.

So switch to all ARM GNU ld toolchains to position independent veneers.

Problem:
As static configuration from the PCDs, the binary PeiCore (for example

Files or PPIs for different platforms.

Burden:
Platform developers need configure the PCDs accordingly for different
platforms.

To solve the problem and remove the burden, we can update code to
remove the using of PcdPeiCoreMaxFvSupported, PcdPeiCoreMaxPeimPerFv
and PcdPeiCoreMaxPpiSupported by extending buffer dynamically for FV,
File and PPI management.
