fix(libtl): typecast expression to match data type

This corrects the MISRA violation C2012-10.1:
Operands shall not be of an inappropriate essential type.
The original code used an expression of a non-Boolean essential type
in a Boolean context. To comply with the rule, the expression has been
replaced with an explicit comparison to a Boolean-compatible
value (e.g., == NULL, != 0U, ensuring clarity and type safety.

Transfer List Library (LibTL)

The Transfer List Library (LibTL) implements the Firmware Handoff specification, providing a streamlined interface for managing transfer lists. LibTL offers a user-friendly interface for:

  • Creating transfer lists
  • Reading and extracting data from transfer lists
  • Manipulating and updating transfer lists

The library supports building with host tools such as Clang and GCC, and cross compilation with the Aarch64 GNU compiler.

Minimum Supporting Tooling Requirements

ToolMinimum Version
Clang-Format14
CMake3.15

Building with CMake

To configure the project with the default settings (using GCC as the host compiler), run:

cmake -B build

Then, to compile the project and produce libtl.a in the build/ directory:

cmake --build build

To cross-compile the project (e.g., for AArch64), specify the appropriate tool using the CC option when configuring the project:

CC=aarch64-none-elf-gcc cmake -B build -DCMAKE_TRY_COMPILE_TARGET_TYPE=STATIC_LIBRARY
cmake --build build

You can specify the build mode using the CMAKE_BUILD_TYPE option. Supported modes include:

  • Debug – Full debug info with no optimization.
  • Release – Optimized build without debug info.
  • RelWithDebInfo – Optimized build with debug info.
  • MinSizeRel – Optimized for minimum size.

APIs for specific projects can be conditionally included in the static library using the PROJECT_API option.

Testing with CTest

Tests for LibTL are provided in the folder test, to configure the project for test builds, run:

cmake -B build -DTARGET_GROUP=test
cmake --build build

Then, to run the tests with ctest, use:

ctest --test-dir build/
