Add CsrRead(), CsrWrite() and CsrXChg() support for IMPCTL1 (0x80),
IMPCTL2 (0x81) and TLBRPRMD (0x8F). These selectors currently reach
the unsupported-selector trap instead of a CSR instruction.
Define the register numbers, add the IMPCTL1/2 dispatch range and
extend the existing TLB refill range and instruction tables through
TLBRPRMD. Preserve the existing handling of all other selectors.
The register definitions follow LoongArch Reference Manual Volume 1,
version 1.10, sections 7.4.18, 7.4.19 and 7.5.17. IMPCTL field semantics
remain implementation-specific; this change only enables CSR access.

The typedef 'uint64_t' in CryptParallelHash.h conflicts with the same
typedef defined in openssl/include/openssl/e_os2.h when both headers are
included in the same translation unit. This causes a redefinition error
with strict compiler flags (-Werror,-Wtypedef-redefinition).
The uint64_t type is already provided through the include chain:
InternalCryptLib.h -> openssl/evp.h -> openssl/e_os2.h
Removing the redundant typedef resolves the conflict while maintaining
compatibility, as the type is still available through the proper include
chain.

Add frame record in CommonExceptionEntry before calling
CommonCExceptionHandler to comply with AArch64 AAPCS calling convention.
This also allows the debugger to reconstruct the full call stack when
a crash occurs in any UEFI module.
Known Limitation :
This only fixes the CommonExceptionEntry() link in the chain.
The final hop from CommonExceptionEntry()'s frame record back into the
interrupted function's own frame is still just the x29 value captured at
exception time.
If the exception was taken while the interrupted function's prologue or
epilogue was still executing, that frame record may be incomplete or
already torn down, and FP-chain unwinding can produce an incorrect
or truncated backtrace for that last frame.

Clang prior to at least v23.1.4 used to merge ELF style section
names for PE targets. However,
https://github.com/llvm/llvm-project/pull/199625 changed that
behavior to only occur for MinGW. This causes newer versions
of clang to not merge together .text sections in edk2 binaries,
creating very large images.
This commit changes the ASM_FUNC and ASM_FUNC_ALIGN macros to
not use the ELF style syntax when building PE images and instead
use PE style section syntax to ensure the sections get merged.

Add support for loading logos from FREEFORM FFS files identified by
PcdLogoFileGuid. When the PCD is zero or invalid, preserve the
existing HII-based logo loading path.
When the PCD is valid non-zero, select the logo from the corresponding RAW
FFS file in the firmware volume, including compressed and uncompressed
section layouts.
Key Difference
- LogoDxe: HII fallback always works (embedded logo available)
- LogoFfsDxe: HII fallback returns EFI_NOT_FOUND (no embedded logo)
Update LogoDxe file descriptions, copyright notices, include ordering,
and INF annotations. Consolidate module includes into single shared
header.

Per issue #9665 (originally BZ 1371), this
adds a DUMP_HEX macro to DebugLib.h to nicely
format printing hexadecimal values from memory.
This pattern is widely used across edk2 and platforms,
but every location implements its own version.

The Config-B TDX firmware shipped with SECURE_BOOT_ENABLE=FALSE and
BUILD_SHELL=TRUE by default, so a default production build performed no
Secure Boot image verification and embedded the full UEFI Shell, giving an
attacker an unauthenticated command environment.
Default SECURE_BOOT_ENABLE to TRUE and BUILD_SHELL to FALSE, matching the
hardened AmdSevX64 posture. Both remain overridable on the build command
line (-D FLAG=VALUE) for development. With Secure Boot enabled the shell FV
is already excluded by ShellDxe.fdf.inc.

InitializePlatform() called PlatformInitEmuVariableNvStore() and discarded
its return value. That store holds the authenticated Secure Boot variables
(PK/KEK/db/dbx) that gate image verification, and it is populated from a
flash template that can be influenced through the untrusted fw_cfg path. If
initialization failed the boot continued with an unverified Secure Boot
configuration.
Propagate the failure out of InitializePlatform() so the pei-less startup
dead-loops instead of proceeding with an invalid variable store.

EnableDisableAP() reads the target processor's status before checking
whether ProcessorNumber is within the per-processor data array. An invalid
index can therefore cause an out-of-bounds read instead of returning
EFI_NOT_FOUND.

index and BSP checks. Read StatusFlag through the validated CpuData pointer
to preserve the existing behavior for valid APs.

The GenerateCapsule tool produces a properly formatted FMP Capsule,
but the original script placed the raw Firmware Volume into the
.cab archive. fwupd expects the payload to already be in EFI Capsule
format when using the org.uefi.capsule protocol, and incorrectly
re-packages the raw FD, resulting in a capsule that the firmware
rejects.
Copy the generated FMP Capsule into the .cab instead of the raw
payload so that fwupd can use it directly without further
modification.
