23 /* The Sandpoint X3 allows the IDE interrupt to be directly connected
24 * from the Windbond (PCI INTC or INTD) to the serial EPIC. Someday
25 * we should try this, but it was easier to use the existing 83c553
26 * initialization than change it to route the different interrupts :-).

34 * The sandpoint boards have processor modules that either have an 8240 or
35 * an MPC107 host bridge on them. These bridges have an IDSEL line that allows
36 * them to respond to PCI transactions as if they were a normal PCI devices.
37 * However, the processor on the processor side of the bridge can not reach
38 * out onto the PCI bus and then select the bridge or bad things will happen
39 * (documented in the 8240 and 107 manuals).
40 * Because of this, we always skip the bridge PCI device when accessing the
41 * PCI bus. The PCI slot that the bridge occupies is defined by the macro
