I also use pci_find_device() to get the bdf value of
the Sil 0680A device on the PCI bus, then use this bdf
to allocate memory for BARs.  And according to the
datasheet, I/O space access, memory space access, and
bus master operation need to be enabled as well.  So
some implementation are needed besides changing the
config params.  Moreover, since I'd like to support
POST for this device and the CF-ATA drives that
connect to it, my driver needs to do more than these
basic steps.
