+ * PIC AS DEVICE ZERO
+ * ------------------
+ *
+ * PIC handles PCI/X busses.  PCI/X requires that the 'bridge' (i.e. PIC)
+ * be designated as 'device 0'.   That is a departure from earlier SGI
+ * PCI bridges.  Because of that we use config space 1 to access the
+ * config space of the first actual PCI device on the bus.
+ * Here's what the PIC manual says:
+ *
+ *     The current PCI-X bus specification now defines that the parent
+ *     hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
+ *     reduced the total number of devices from 8 to 4 and removed the
+ *     device registers and windows, now only supporting devices 0,1,2, and
+ *     3. PIC did leave all 8 configuration space windows. The reason was
+ *     there was nothing to gain by removing them. Here in lies the problem.
+ *     The device numbering we do using 0 through 3 is unrelated to the device
+ *     numbering which PCI-X requires in configuration space. In the past we
+ *     correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
+ *     PCI-X requires we start a 1, not 0 and currently the PX brick
+ *     does associate our:
+ *
+ *         device 0 with configuration space window 1,
+ *         device 1 with configuration space window 2,
+ *         device 2 with configuration space window 3,
+ *         device 3 with configuration space window 4.
+ *
+ * The net effect is that all config space access are off-by-one with
+ * relation to other per-slot accesses on the PIC.
+ * Here is a table that shows some of that:
+ *
+ *                               Internal Slot#
+ *           |
