- * 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#
- *           |
- *           |     0         1        2         3
- * ----------|---------------------------------------
- * config    |  0x21000   0x22000  0x23000   0x24000
- *           |
- * even rrb  |  0[0]      n/a      1[0]      n/a        [] == implied even/odd
- *           |
- * odd rrb   |  n/a       0[1]     n/a       1[1]
- *           |
- * int dev   |  00       01        10        11
