- * 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

+ * 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
