+ * Driver Registration Subsystem
+ *
+ * Provides a linker-set based registration mechanism for hardware drivers.
+ * Drivers define a probe function and register it with the REGISTER_DRIVER macro.
+ * During boot, driver_probe_all() scans the Device Tree (FDT) and invokes the
+ * probe function for any matching compatible strings.
+ *
+ * This decouples the MI kernel initialization from MD driver specifics.
