AsciiStrCat() is deprecated / disabled under the
DISABLE_NEW_DEPRECATED_INTERFACES feature test macro.
The caller of CpsrString() is required to pass in "ReturnStr" with 32
CHAR8 elements. (DefaultExceptionHandler() complies with this.) "Str" is
used to build "ReturnStr" gradually. Just before calling AsciiStrCat(),
"Str" points to the then-terminating NUL character in "ReturnStr".
The difference (Str - ReturnStr) gives the number of non-NUL characters
we've written thus far, hence (32 - (Str - ReturnStr)) yields the number
of remaining bytes in ReturnStr, including the ultimately terminating NUL
character.

AsciiStrCat() is deprecated / disabled under the
DISABLE_NEW_DEPRECATED_INTERFACES feature test macro.
The "Str" variable serves no particular purpose in the MRegList() and
ThumbMRegList() functions; replace it with the pointed-to "mMregListStr" /
"mThumbMregListStr" global variable (as appropriate), so that the new
AsciiStrCatS() calls are as clear as possible.

During Mmu initialization in the CpuDxe, for a page table any bits set
in the 'NextSectionAttributes' are garbage and were set from bits that
are actually part of the pagetable address. We clear it out to zero
so that the SyncCacheConfigPage will use the page attributes instead
of trying to convert the (bogus) section attributes into page
attributes.

As reported by Eugene, the practice of sizing the address space in the
virtual memory system based on the maximum address in the table passed
to ArmConfigureMmu() is problematic, since it fails to take into account
the fact that the GCD memory space may be extended at a later time, both
for memory and for MMIO. So instead, choose the VA size identical to the
GCD memory map size, which is based on PcdPrePiCpuMemorySize on ARM
systems.

Currently, we allocate a full page for the root translation table, even
if the configured translation only requires two entries (16 bytes) for
the root level, which happens to be the case for a 40 bit VA. Likewise,
for a 36-bit VA space, the root table only needs 16 entries of 8 bytes
each, adding up to 128 bytes.
So switch to a pool allocation for the root table if we can, but take into
account that the architecture requires it to be naturally aligned to its
size, i.e., a 64 byte table requires 64 byte alignment, whereas pool
allocations in general are only guaranteed to be aligned to 8 bytes.

In commit 7d189f99d81c ("ArmPkg/Mmu: Fix bug of aligning new allocated
page table"), we fixed a flaw in the logic regarding alignment of newly
allocated translation table pages. However, we all failed to spot that
aligning page based allocations to page size is rather pointless to
begin with, so simply allocate a single page each time we add new pages
to the translation tables.
Also, drop the unnecessary cast.

The relations between T0SZ, the number of translation levels and the
size/alignment of the root table can be expressed in simple arithmetic
expressions, so get rid of the lookup table.
Note that this disregards the fact that the maximum value of T0SZ is
39 not 42 (as one would expect for the smallest VA size using 2 levels)
but since this corresponds to a VA size of 32 MB and 4 MB, respectively,
neither of which are sufficient to run UEFI, we can safely ignore the
distinction.

For historical reasons, the files under ArmLib are split up into 'common'
files under Common/, containing common C files as well as AArch64 and Arm
specific asm files, and ArmV7 and AArch64 files under ArmV7/ and AArch64/,
respectively. This presumably dates back to the time when ArmLib supported
different revisions of the 32-bit architecture (i.e., pre-V7)
Since the PI spec requires V7 or later, we can simplify this to Arm/ and
AArch64, which aligns ArmLib with the majority of other modules that carry
ARM or AArch64 specific code.
So move the files around so that shared files live at the same level as
ArmBaseLib.inf, and ARM/AArch64 specific files live in Arm/ or AArch64/,
respectively.

After the recent update of CompilerIntrinsicsLib, our memset() is no
longer emitted as a weak symbol. On ARM, this may cause problems when
combining this library with another library that supplies memset() [e.g.,
CryptoPkg/IntrinsicLib], due to the fact that the object also supplies
the __aeabi_memXXX entry points, which can only be satisfied by this
object. So make our memset() weak again, to let the other implementation
take precedence.

This replaces the various implementations of memset and memcpy,
including the ARM RTABI ones (__aeabi_mem[set|clr]_[|4|8]) with
a single C implementation for each. The ones we have are either not
very sophisticated (ARM), or they are too sophisticated (memcpy() on
AARCH64, which may perform unaligned accesses) or already coded in C
(memset on AArch64).
The Tianocore codebase mandates the explicit use of its SetMem() and
CopyMem() equivalents, of which various implementations exist for use
in different contexts (PEI, DXE). Few compiler generated references to
these functions should remain, and so our implementations in this BASE
library should be small and usable with the MMU off.
So replace them with a simple C implementation that builds correctly
on GCC/AARCH64, CLANG/AARCH64, GCC/ARM, CLANG/ARM and RVCT/ARM.

The C language is powerful enough to implement a function that does
absolutely nothing, so there is no need to resort to implementations
in assembler for various toolchains/architectures.

This introduces the ASM_FUNC() macro to annotate function entry points
in assembler files. This allows us to add additional metadata that
marks a function entry point as a function, and allows us to emit
a .section directive for each function, which makes it possible for
the linker to drop unreferenced code.
In addition, introduce a couple of utility macros that we can use to
clean up the code.

This removes the various Mmio ASM macros that are not used anywhere in
the code, and removes some variants of LoadConstant... () that are not
used anywhere either.
Note that these MmioXxx() implementations are unrelated to the C versions
defined in MdePkg. These are strictly intended for use in assembler, and
no such uses remain.

The function ArmReplaceLiveTranslationEntry() has been moved to
ArmMmuLib, so remove the old implementation from ArmLib.
Note that the new implementation was not exported from the object file,
and so references to it were satisfied by the old version residing in
ArmLib. Since we are removing that one, we need to export the new one
at the same time to prevent the linker from bailing with undefined
reference errors.

This commit fixes a bug in the GIC v2 and v3 drivers where the GICC_EOIR
(End Of Interrupt Register) is written twice for a single interrupt.
GicV(2|3)IrqInterruptHandler() calls the Interrupt Handler and then
GicV(2|3)EndOfInterrupt() on exit:
InterruptHandler = gRegisteredInterruptHandlers[GicInterrupt];
if (InterruptHandler != NULL) {
// Call the registered interrupt handler.
InterruptHandler (GicInterrupt, SystemContext);
} else {
DEBUG ((EFI_D_ERROR, "Spurious GIC interrupt: 0x%x\n", GicInterrupt));
}
GicV2EndOfInterrupt (&gHardwareInterruptV2Protocol, GicInterrupt);
although gInterrupt->EndOfInterrupt() can be expected to have already
been called by InterruptHandler() [which is the case for the primary
in-tree handler in TimerDxe]
The fix moves the EndOfInterrupt() call inside the else case for
unregistered/spurious interrupts. This removes a potential race
condition that might have lost interrupts.

The ARM compiler intrinsics library defines __aeabi_memset() and
memset() in the same object, which means that both will be pulled
in if either is referenced.
The IntrinsicLib in CryptoPkg defines its own, preferred memset(),
which may clash with our memset(). So make our version weak.

Building ArmSoftFloatLib with LTO results in errors like
.../bin/ld: softfloat.obj: plugin needed to handle lto object
.../bin/ld: __aeabi_dcmpge.obj: plugin needed to handle lto object
.../bin/ld: __aeabi_dcmplt.obj: plugin needed to handle lto object
.../bin/ld: internal error ../../ld/ldlang.c 6299
This library is only linked by OpensslLib at the moment, and only
marginally used at runtime, so just disable LTO for it.

GCC in LTO mode interoperates poorly with non-standard libraries that
provide implementations of compiler intrinsics such as memcpy/memset
or the stack protector entry points. Such libraries need to be built
in non-LTO mode, and then referenced explicitly on the linker command
line using a -plugin-opt=-pass-through=-lxxx linker option.
However, if these intrinsics are also referenced directly, the LTO
version of the code will be pulled in, and will happily satisfy all
other references to the same symbol.
So add a pair of glue libraries, for ARM and AARCH64, that reference
the known intrinsics. Since the binaries live under ArmPkg directly,
we can reference them in tools_def.txt. Under LD garbage collection,
the object itself will be pruned, and so will the intrinsics that end
up unused by the module.

Unlike SGIs and PPIs, which are private to the CPU and are managed at
the redistributor level (which is also a per-CPU construct), shared
interrupts (SPIs) are shared between all CPUs, and therefore managed at
the distributor level (just as on GICv2).
