- * Since the IQ80331 is a slave card on a PCI backplane,

- * use with the private devices on the secondary bus
- * (GigE and PCI-X slot). We read BAR1 and configure
- * our outbound translation windows to target that
- * address range and assign all devices in that
- * address range. W/O this, certain BIOSes will fail
- * to boot as the IQ80331 claims addresses that are
- * in use by other devices.
- *
- * Note that the same cannot be done with I/O space,
- * so hopefully the host will stick to the lower 64K for
- * PCI I/O and leave us alone.
