Hi, Libra,
Do the definitions of PMIO apply to all the chipset?
+void speaker_timer_on(void)
+{
+ /* Setting this bit will configure GPIO to be speaker output */
+#ifndef EARLY_STAGE
+ pm_iowrite(0x60, (pmio_read(0x60) | (1<<5)));
+#else

+#endif // EARLY_STAGE
+ outb((inb(PPC_PORTB) | PPCB_SPKR), PPC_PORTB);
+}

+void speaker_timer_off(void)
+{
+ outb((inb(PPC_PORTB) & ~PPCB_SPKR), PPC_PORTB);
+}
