+- Interrupt support (PPC):
+
+                There are common interrupt_init() and timer_interrupt()
+                for all PPC archs. interrupt_init() calls interrupt_init_cpu()
+                for cpu specific initialization. interrupt_init_cpu()
+                should set decrementer_count to appropriate value. If
+                cpu resets decrementer automatically after interrupt
+                (ppc4xx) it should set decrementer_count to zero.
+                timer_interrupt() calls timer_interrupt_cpu() for cpu
+                specific handling. If board has watchdog / status_led
