043615ae8b MdePkg/BaseLib: Add NULL version Tdx functions for other architectures
Currently, the NULL version Tdx functions are only built for Ia32.
In BaseLib, the others architectures also need such NULL version
Tdx functions.

a29a9cce5f MdePkg/BaseLib: Add CRC16 CCITT False Implementation.
This change is added to incorporate basic implementation for
CRC16-CCITT-FALSE algorithm.

This function is useful for providing CRC16 value used in other data
structures that requires CRC16 value that complies with JEDEC SPD
requirements, i.e. BDAT table.

The lookup table is inherited from `https://crccalc.com/` and the result
values are also compared against this site.

c0bf953fe8 MdePkg/BaseLib: Add a new VMGEXIT instruction invocation for SVSM
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4654

The SVSM specification relies on a specific register calling convention to
hold the parameters that are associated with the SVSM request. The SVSM is
invoked by requesting the hypervisor to run the VMPL0 VMSA of the guest
using the GHCB MSR Protocol or a GHCB NAE event.

Create a new version of the VMGEXIT instruction that will adhere to this
calling convention and load the SVSM function arguments into the proper
register before invoking the VMGEXIT instruction. On return, perform the
atomic exchange on the SVSM call pending value as specified in the SVSM
specification.

26727c2ae2 MdePkg: Implement RISC-V Cache Management Operations
Implement Cache Management Operations (CMO) defined by
RISC-V spec https://github.com/riscv/riscv-CMOs.

Notes:
1. CMO only supports block based Operations. Meaning cache
   flush/invd/clean Operations are not available for the entire
   range. In that case we fallback on fence.i instructions.
2. Operations are implemented using Opcodes to make them compiler
   independent. binutils 2.39+ compilers support CMO instructions.

Test:
1. Ensured correct instructions are refelecting in asm
2. Qemu implements basic support for CMO operations in that it allwos
   instructions without exceptions. Verified it works properly in
   that sense.
3. SG2042Pkg implements CMO-like instructions. It was verified that
   CpuFlushCpuDataCache works fine. This more of less
   confirms that framework is alright.
4. TODO: Once Silicon is available with exact instructions, we will
   further verify this.

patches. Current method is fence instruction based, rename the
function accordingly to add that clarity.

e2d4f75913 MdePkg/BaseLib: Fix CRC16-ANSI calculation
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4609

The current CalculateCrc16Ansi implementation does the following:
1) Invert the passed checksum
2) Calculate the new checksum by going through data and using the
   lookup table
3) Invert it back again

This emulated my design for CalculateCrc32c, where 0 is
passed as the initial checksum, and it inverts in the end.
However, CRC16 does not invert the checksum on input and output.
So this is incorrect.

Fix the problem by not inverting input checksums nor output checksums.
Callers should now pass CRC16ANSI_INIT as the initial value instead of
"0". This is a breaking change.

This problem was found out-of-list when older ext4 filesystems
(that use crc16 checksums) failed to mount with "corruption".

Since SEV-ES is only supported in X64, provide the necessary X64 support
to execute the VMGEXIT instruction, which is coded as "rep vmmcall". For
IA32, since "vmmcall" is not supported in NASM 32-bit mode and VMGEXIT
should never be called, provide a stub implementation that is identical
to CpuBreakpoint().

9b3ca509ab MdePkg/BaseLib: Add support for the XGETBV instruction
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2198

Under SEV-ES, a CPUID instruction requires the current value of the XCR0
register. In order to retrieve that value, the XGETBV instruction needs
to be executed.

Provide the necessary support to execute the XGETBV instruction.

09fe015af9 MdePkg: Fix SafeString performing assertions on runtime checks
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2054

Runtime checks returned via status return code should not work as
assertions to permit parsing not trusted data with SafeString
interfaces.  Replace ASSERT() with a DEBUG_VERBOSE message.

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1959

The macros EFI_LIST_FOR_EACH and EFI_LIST_FOR_EACH_SAFE have been
duplicated across several drivers. These macros have proven useful and
established a commonly used pattern for linked list iteration.

This change defines the macros in BaseLib.h alongside other generic linked
list macros and functions.
