[coreboot] [PATCH] The PC buzzer

[Bao, Zheng]

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

+     pmio_write(0x60, (pmio_read(0x60) | (1<<5)));

+#endif // EARLY_STAGE

+     outb((inb(PPC_PORTB) | PPCB_SPKR), PPC_PORTB);

+}

+

+void speaker_timer_off(void)

+{

+     outb((inb(PPC_PORTB) & ~PPCB_SPKR), PPC_PORTB);

+}

+

 

 

 

Zheng
