Try apply the following (you'll have to do it by hand). This turns
off the XV and YV bits always. This code is src/sys/dev/pccbb/pccbb.c
Warner
static int
cbb_do_power(device_t brdev)
{
struct cbb_softc *sc = device_get_softc(brdev);
uint32_t voltage, curpwr;
uint32_t status;
/* Don't enable OE (output enable) until power stable */
exca_clrb(&sc->exca[0], EXCA_PWRCTL, EXCA_PWRCTL_OE);
- voltage = cbb_detect_voltage(brdev);
+ voltage = cbb_detect_voltage(brdev) & ~(CARD_XV_CARD | CARD_YV_CARD);
curpwr = cbb_current_voltage(brdev);
status = cbb_get(sc, CBB_SOCKET_STATE);
if ((status & CBB_STATE_POWER_CYCLE) && (voltage & curpwr))
return 0;
/* Prefer lowest voltage supported */
cbb_power(brdev, CARD_OFF);
if (voltage & CARD_YV_CARD)
cbb_power(brdev, CARD_VCC(YV));
else if (voltage & CARD_XV_CARD)
cbb_power(brdev, CARD_VCC(XV));
else if (voltage & CARD_3V_CARD)
cbb_power(brdev, CARD_VCC(3));
else if (voltage & CARD_5V_CARD)
cbb_power(brdev, CARD_VCC(5));
else {
device_printf(brdev, "Unknown card voltage\n");
return (ENXIO);
}
return (0);
}
