Thanks to Thomas we now know how to detect the 96x SiS SB. The patch
against 2.4.20 uses the documentated method to use the correct router
function and hence make new SiS chipsets to work with the new USB routing
registers. Tested and working fine on my machine.

- * PIRQ routing for SiS 85C503 router used in several SiS chipsets
- * According to the SiS 5595 datasheet (preliminary V1.0, 12/24/1997)
- * the related registers work as follows:
- *
- * general: one byte per re-routable IRQ,
+ * PIRQ routing for SiS 85C503 router used in several SiS chipsets.
+ * We have to deal with the following issues here:
+ * - vendors have different ideas about the meaning of link values
+ * - some onboard devices (integrated in the chipset) have special
+ * links and are thus routed differently (i.e. not via PCI INTA-INTD)
+ * - different revision of the router have a different layout for
+ * the routing registers, particularly for the onchip devices
+ *
+ * For all routing registers the common thing is we have one byte
+ * per routeable link which is defined as:
* bit 7 IRQ mapping enabled (0) or disabled (1)
- * bits [6:4] reserved
+ * bits [6:4] reserved (sometimes used for onchip devices)
* bits [3:0] IRQ to map to
* allowed: 3-7, 9-12, 14-15
* reserved: 0, 1, 2, 8, 13
*
- * individual registers in device config space:
+ * The config-space registers located at 0x41/0x42/0x43/0x44 are
+ * always used to route the normal PCI INT A/B/C/D respectively.
+ * Apparently there are systems implementing PCI routing table using
+ * link values 0x01-0x04 and others using 0x41-0x44 for PCI INTA..D.
+ * We try our best to handle both link mappings.
+ *
+ * Currently (2003-05-21) it appears most SiS chipsets follow the
+ * definition of routing registers from the SiS-5595 southbridge.
+ * According to the SiS 5595 datasheets the revision id's of the
+ * router (ISA-bridge) should be 0x01 or 0xb0.
*
- * 0x41/0x42/0x43/0x44: PCI INT A/B/C/D - bits as in general case
+ * Furthermore we've also seen lspci dumps with revision 0x00 and 0xb1.
+ * Looks like these are used in a number of SiS 5xx/6xx/7xx chipsets.
+ * They seem to work with the current routing code. However there is
+ * some concern because of the two USB-OHCI HCs (original SiS 5595
+ * had only one). YMMV.
*
- * 0x61: IDEIRQ: bits as in general case - but:
- * bits [6:5] must be written 01
- * bit 4 channel-select primary (0), secondary (1)
+ * Onchip routing for router rev-id 0x01/0xb0 and probably 0x00/0xb1:
*
- * 0x62: USBIRQ: bits as in general case - but:
- * bit 4 OHCI function disabled (0), enabled (1)
+ * 0x61: IDEIRQ:
+ * bits [6:5] must be written 01
+ * bit 4 channel-select primary (0), secondary (1)
+ *
+ * 0x62: USBIRQ:
+ * bit 6 OHCI function disabled (0), enabled (1)
*
- * 0x6a: ACPI/SCI IRQ - bits as in general case
+ * 0x6a: ACPI/SCI IRQ: bits 4-6 reserved
+ *
+ * 0x7e: Data Acq. Module IRQ - bits 4-6 reserved
*
- * 0x7e: Data Acq. Module IRQ - bits as in general case
+ * We support USBIRQ (in addition to INTA-INTD) and keep the
+ * IDE, ACPI and DAQ routing untouched as set by the BIOS.
*
- * Apparently there are systems implementing PCI routing table using both
- * link values 0x01-0x04 and 0x41-0x44 for PCI INTA..D, but register offsets
- * like 0x62 as link values for USBIRQ e.g. So there is no simple
- * "register = offset + pirq" relation.
- * Currently we support PCI INTA..D and USBIRQ and try our best to handle
- * both link mappings.
- * IDE/ACPI/DAQ mapping is currently unsupported (left untouched as set by BIOS).
+ * Currently the only reported exception is the new SiS 65x chipset
+ * which includes the SiS 69x southbridge. Here we have the 85C503
+ * router revision 0x04 and there are changes in the register layout
+ * mostly related to the different USB HCs with USB 2.0 support.
+ *
+ * Onchip routing for router rev-id 0x04 (try-and-error observation)
+ *
+ * 0x60/0x61/0x62/0x63: 1xEHCI and 3xOHCI (companion) USB-HCs
+ * bit 6-4 are probably unused, not like 5595
