+/**
+ * @file memory.h  macro's for malloc() and free()
+ *
+ * these are usually defined in clib's stdlib.h, but zephyr requires the use of
+ * the k_malloc and k_free functions for memory management, thus this file is
+ * used to set aliases for each respecive platform's native memory management
+ * functions as they have the same function signature. these macro's should be
+ * defined using a compiler flag
