* The three PCI devices on the motherboard have dedicated lines to the
* CPLD interrupt controller, bypassing the standard PCI INTA-D and the
* PC interrupt controller. All other PCI devices (slots) have usual
* staggered INTA-D lines, resulting in 8 lines total (PCI0 INTA-D and
* PCI1 INTA-D). All 8 go to the CPLD interrupt controller. PCI0 INTA-D
* also go to the south bridge, so we have the option of taking them
* via the CPLD interrupt controller or via the south bridge 8259
* 8258 thingy. PCI1 INTA-D can only be taken via the CPLD interrupt
* controller. We take all PCI interrupts via the CPLD interrupt
* controller as recommended by SBS.
*
* We also have some monkey business with the PCI devices within the
* VT82C686B south bridge itself. This chip actually has 7 functions on
* its IDSEL. Function 0 is the actual south bridge, function 1 is IDE,
* and function 4 is some special stuff. The other 4 functions are just
* regular PCI devices bundled in the chip. 2 and 3 are USB UHCIs and 5
* and 6 are audio (not supported on the Adirondack).
*
* This is where the monkey business begins. PCI devices are supposed
* to signal normal PCI interrupts. But the 4 functions in question are
* located in the south bridge chip, which is designed with the
* assumption that it will be fielding PCI INTA-D interrupts rather
* than generating them. Here's what it does. Each of the functions in
* question routes its interrupt to one of the IRQs on the 8259 thingy.
* Which one? It looks at the Interrupt Line register in the PCI config
* space, even though the PCI spec says it's for BIOS/OS interaction
* only.
*
* How do we deal with this? We take these interrupts via 8259 IRQs as
* we have to. We return the desired IRQ numbers from this routine when
* called for the functions in question. The PCI scan code will then
* stick our return value into the Interrupt Line register in the PCI
* config space, and the interrupt will actually go there. We identify
* these functions within the south bridge IDSEL by their interrupt pin
* numbers, as the VT82C686B has 04 in the Interrupt Pin register for
* USB and 03 for audio.
