MdePkg/BaseFdtLib: Update libfdt submodule

2026-09-21T11:28:06+00:00

Update libfdt submodule to commit f48b965 of pylibfdt. Repo: https://github.com/devicetree-org/pylibfdt Commit: f48b965 This moves to dtc v1.7.2-24-gf4c53f4ebf78. Signed-off-by: Vishal Oliyil Kunnil

MdePkg/BaseFdtLib: Use BaseLib strrchr/strtoul, drop LibFdtWrapper.c

2026-09-15T10:49:49+00:00

Point the strrchr and strtoul macros in LibFdtSupport.h at the new AsciiStrRChr() and AsciiStrToUintn() BaseLib APIs instead of the private fdt_strrchr()/fdt_strtoul() implementations. This removes duplicated logic and picks up the overflow-detection already present in the underlying AsciiStrHexToUintnS()/AsciiStrDecimalToUintnS() conversion routines. LibFdtWrapper.c is now empty of purpose and is removed, along with its entry in BaseFdtLib.inf. Signed-off-by: Vishal Oliyil Kunnil

MdePkg/BaseFdtLib: Add FdtStringListCount and FdtStringListSearch wrappers

2026-06-04T06:55:42+00:00

Add UEFI-native wrappers for libfdt string list count and search APIs. Signed-off-by: Thamballi Sreelalitha

MdePkg/BaseFdtLib: Header style update to FdtOverlayApply and

2026-03-24T13:24:38+00:00

FdtStrerror Update the FdtOverlayApply() function to mark the Fdt pointer as an IN OUT variable. The internal fdt_overlay_apply() function returns the merged blob in the Fdt variable. Update FdtStrerror to have it's return type on a single line, aligning the style with the rest of the file. Signed-off-by: Antaeus Kleinert-Strand

MdePkg/BaseFdtLib: FdtGetName, FdtGetPath

2026-03-24T13:24:38+00:00

Update FdtGetName() and FdtGetPath() to correctly mark the VOID *Fdt as a CONST variable. This aligns with the internal libfdt implementation. Update MockFdtLib.h to align with the updated inputs for FdtGetName() and FdtGetPath(). Signed-off-by: Antaeus Kleinert-Strand

MdePkg/BaseFdtLib: Implement new libfdt wrappers

2026-03-24T13:24:38+00:00

Add support for the define FdtForEachPropertyOffset and FdtFindMaxPhandle() wrappers. Signed-off-by: Antaeus Kleinert-Strand

MdePkg: Replace include guards with #pragma once

2026-02-23T21:01:28+00:00

Replace traditional `#ifndef`/`#define`/`#endif` include guards with `#pragma` once. `#pragma once` is a widely supported preprocessor directive that prevents header files from being included multiple times. It is supported by all toolchains used to build edk2: GCC, Clang/LLVM, and MSVC. Compared to macro-based include guards, `#pragma once`: - Eliminates the risk of macro name collisions or copy/paste errors where two headers inadvertently use the same guard macro. - Eliminate inconsistency in the way include guard macros are named (e.g., some files use `__FILE_H__`, others use `FILE_H_`, etc.). - Reduces boilerplate (three lines replaced by one). - Avoids polluting the macro namespace with guard symbols. - Can improve build times as the preprocessor can skip re-opening the file entirely, rather than re-reading it to find the matching `#endif` ("multiple-include optimization"). - Note that some compilers may already optimize traditional include guards, by recognzining the idiomatic pattern. This change is made acknowledging that overall portability of the code will technically be reduced, as `#pragma once` is not part of the C/C++ standards. However, this is considered acceptable given: 1. edk2 already defines a subset of supported compilers in BaseTools/Conf/tools_def.template, all of which have supported `#pragma once` for over two decades. 2. There have been concerns raised to the project about inconsistent include guard naming and potential macro collisions. Approximate compiler support dates: - MSVC: Supported since Visual C++ 4.2 (1996) - GCC: Supported since 3.4 (2004) (http://gnu.ist.utl.pt/software/gcc/gcc-3.4/changes.html) - Clang (LLVM based): Since initial release in 2007 Signed-off-by: Michael Kubacki

2026-01-21T03:46:30+00:00

VS2022 NOOPT IA32 builds of BaseFdtLib introduce use of intrinsics __allshl and __aullshr from the libfdt submodule that can not be modified. Add the implementation of __allshl and __aullshr intrinsics from from the CryptoPkg to BaseFdtLib. Signed-off-by: Michael D Kinney
