- * @defgroup HAL HAL Driver
- * @brief Hardware Abstraction Layer.
- * @details The HAL (Hardware Abstraction Layer) driver performs the system
- * initialization and includes the platform support code shared by
- * the other drivers. This driver does contain any API function
- * except for a general initialization function @p halInit() that
- * must be invoked before any HAL service can be used, usually the
- * HAL initialization should be performed immediately before the
- * kernel initialization.<br>
- * Some HAL driver implementations also offer a custom early clock
- * setup function that can be invoked before the C runtime
- * initialization in order to accelerate the startup time.
