Problem about the new sdhci driver

[Henry Hu]

Hi,

I'm using FreeBSD 7-STABLE, with sdhci driver
sdhci.20081029.tgz
mmc.20081029.tgz

I've found that if I load sdhci driver with card inserted, everything
works fine.
But if I load sdhci driver first, and then insert card, the card is
not detected.Additionally, there is no interrupt.
After I've load sdhci driver without card, the controller seems to be
in a problematic state. The register dump outputed when the driver
loaded showed that Present is 0x01f20000 which is correct since the
card is not inserted then. But cards is not detected.
Even if I unload the driver and reload with card inserted, the card
still cannot be detected, and there's no interrupt. But the Present
register changed to 0x01fa0000 which is strange.

So I guess there's something wrong with the driver when the card is not present.
