Ard Biesheuvel 87b920fe22 MdePkg/Arm/ProcessorBind.h: fix copy/paste error
Instead of #defining MAX_ALLOC_ADDRESS to MAX_ADDRESS as intended,
it is #defined to itself, causing all ARM builds to break.

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.

Sean Brogan d7a09cb86a MdePkg/BaseSafeIntLib: Add SafeIntLib class and instance
https://bugzilla.tianocore.org/show_bug.cgi?id=798

SafeIntLib provides helper functions to prevent integer overflow
during type conversion, addition, subtraction, and multiplication.

Conversion Functions
====================
* Converting from a signed type to an unsigned type of the same
  size, or vice-versa.
* Converting to a smaller type that could possibly overflow.
* Converting from a signed type to a larger unsigned type.

Unsigned Addition, Subtraction, Multiplication
===============================================
* Unsigned integer math functions protect from overflow and
  underflow (in case of subtraction).

Signed Addition, Subtraction, Multiplication
============================================
* Strongly consider using unsigned numbers.
* Signed numbers are often used where unsigned numbers should
  be used. For example file sizes and array indices should always
  be unsigned. Subtracting a larger positive signed number from a
  smaller positive signed number with SafeInt32Sub() will succeed,
  producing a negative number, that then must not be used as an
  array index (but can occasionally be used as a pointer index.)
  Similarly for adding a larger magnitude negative number to a
  smaller magnitude positive number.
* SafeIntLib does not protect you from such errors. It tells you
  if your integer operations overflowed, not if you are doing the
  right thing with your non-overflowed integers.
* Likewise you can overflow a buffer with a non-overflowed
  unsigned index.

Leif Lindholm 5b8766bb92 MdePkg: Arm/AArch64 - filter #pragma pack() when __ASSEMBLER__
clang, when used as a preprocessor for dtc, does not discard #pragma
statements although -x assembler-with-cpp is specified. This causes dtc
to barf at a #pragma pack() statement that is already filtered out for
__GNUC__. So add a check to also filter this out if __ASSEMBLER__.

and granularity of page allocations that are visible to the OS as
EFI_MEMORY_RUNTIME regions.

So define macros that carry these values to the respective ProcessorBind.h
header files.

Ard Biesheuvel 82df618711 MdePkg RVCT: add definition of UNREACHABLE
The RVCT compiler in --gnu mode appears to simply strip of the __builtin
prefix when it encounters calls to __builtin_xxx() functions, and so
the __builtin_unreachable() we emit for GCC results in linker errors
regarding undefined references against 'unreachable()'.

So define UNREACHABLE() to a NOP instead.
