chore: add .clang-format for consistent code style

Introduce a .clang-format configuration file to standardize code
formatting across the project. This ensures consistent style, especially
around indentation, brace wrapping, spacing, and line limits, aligning
with project-specific formatting preferences.

While we are it, update the documentation with some minimum supported
tooling requirements.

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, use the following command. This will default to using GCC as the toolchain and create a build directory named build/:

cmake -B build

To build the project, use:

cmake --build build

This will output libtl.a in the build directory.

For cross-compilation or selecting a different compiler, specify the target toolchain file using the CMAKE_TOOLCHAIN_FILE option and the target with CROSS_COMPILE:

export CROSS_COMPILE=aarch64-none-elf-
cmake -B build -DCMAKE_TOOLCHAIN_FILE=toolchains/host/gnu.cmake

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/
