4 * This chip is a horrid piece of engineering, and National

34/* NOTES:
35 *
36 * Function 0 is an IDE controller. It is identical to a PC87415 IDE
37 * controller (and identifies itself as such).
38 *
39 * Function 1 is a "Legacy I/O" controller. Under this function is a
40 * whole mess of legacy I/O peripherals. Of course, HP hasn't enabled
41 * all the functionality in hardware, but the following is available:
42 *
43 * Two 16550A compatible serial controllers
44 * An IEEE 1284 compatible parallel port
45 * A floppy disk controller
46 *
47 * Function 2 is a USB controller.
48 *
49 * We must be incredibly careful during initialization. Since all
50 * interrupts are routed through function 1 (which is not allowed by
51 * the PCI spec), we need to program the PICs on the legacy I/O port
52 * *before* we attempt to set up IDE and USB. @#$!&
53 *
54 * According to HP, devices are only enabled by firmware if they have
55 * a physical device connected.
56 *
57 * Configuration register bits:
58 * 0x5A: FDC, SP1, IDE1, SP2, IDE2, PAR, Reserved, P92
59 * 0x5B: RTC, 8259, 8254, DMA1, DMA2, KBC, P61, APM
