The SATA controller driver crashes while accessing the
PCI memory [AHCI Base Registers (ABAR)], as the PCI memory
space is not enabled.
Enable the PCI memory space access to prevent the SATA
Controller driver from crashing.

The MdePkg/Library/SmmMemoryAllocationLib, used only by DXE_SMM_DRIVER,
allows to free memory allocated in DXE (before EndOfDxe). This is done
by checking the memory range and calling gBS services to do real
operation if the memory to free is out of SMRAM. If some memory related
features, like Heap Guard, are enabled, gBS interface will turn to
EFI_CPU_ARCH_PROTOCOL.SetMemoryAttributes(), provided by
DXE driver UefiCpuPkg/CpuDxe, to change memory paging attributes. This
means we have part of DXE code running in SMM mode in certain
circumstances.
Because page table in SMM mode is different from DXE mode and CpuDxe
always uses current registers (CR0, CR3, etc.) to get memory paging
attributes, it cannot get the correct attributes of DXE memory in SMM
mode from SMM page table. This will cause incorrect memory manipulations,
like fail the releasing of Guard pages if Heap Guard is enabled.
The solution in this patch is to store the DXE page table information
(e.g. value of CR0, CR3 registers, etc.) in a global variable of CpuDxe
driver. If CpuDxe detects it's in SMM mode, it will use this global
variable to access page table instead of current processor registers.
This can avoid retrieving wrong DXE memory paging attributes and changing
SMM page table attributes unexpectedly.

When capsule updates are staged for processing after a warm reboot,
they are copied into memory with the MMU and caches enabled. When
the capsule PEI gets around to coalescing the capsule, the MMU and
caches may still be disabled, and so on architectures where uncached
accesses are incoherent with the caches (such as ARM and AARCH64),
we need to ensure that the data passed into UpdateCapsule() is
written back to main memory before performing the warm reboot.
Unfortunately, on ARM, the only type of cache maintenance instructions
that are suitable for this purpose operate on virtual addresses only,
and given that the UpdateCapsule() prototype includes the physical
address of a linked list of scatter/gather data structures that are
mapped at an address that is unknown to the firmware (and may not even
be mapped at all when UpdateCapsule() is invoked), we can only perform
this cache maintenance at boot time. Fortunately, both Windows and Linux
only invoke UpdateCapsule() before calling ExitBootServices(), so this
is not a problem in practice.
In the future, we may propose adding a secure firmware service that
permits performing the cache maintenance at OS runtime, in which case
this code may be enhanced to call that service if available. For now,
we just fail any UpdateCapsule() calls performed at OS runtime on ARM.

As a security measure, some distros now build their GCC toolchains with
PIE code generation enabled by default, because it is a prerequisite
for ASLR to be enabled when running the executable.
This typically results in slightly larger code, but it also generates
ELF relocations that our tooling cannot deal with, so let's disable it
explicitly when using GCC49 or later for IA32. (Note that this does not
apply to X64: it uses PIE code deliberately in some cases, and our
tooling does deal with the resuling relocations)

and KVM produces a warning such as the following in the kernel log
kvm [17646]: load/store instruction decoding not implemented
The IoLib implementation provided by MdePkg/Library/BaseIoLibIntrinsic
is based on C code, and when LTO is in effect, the MMIO accesses could
be merged with, e.g., manipulations of the loop counter, producing
opcodes that KVM does not support for emulated MMIO.
So let's add a special ArmVirt flavor of this library that implements
that actual load/store operations in assembler, ensuring that the
instructions involved can be emulated by KVM.
