MdePkg: Remove the macro definitions regarding Opcode. REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3790 Remove the macro definitions regarding Opcode because new version of NASM tool(e.g. v2.15.05) supports the corresponding instructions. Note: This patch need to be merged after other NASM code change to avoid compilation errors.

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.

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.
