18 | * The initial version of this is by Martin Peterson. Alex deVries |
19 | * has spent a bit of time trying to coax it into working. | |
20 | * | |
21 | * Major changes to get basic interrupt infrastructure working to | |
22 | * hopefully be able to support all SuperIO devices. Currently | |
23 | * works with serial. -- John Marvin <jsm@fc.hp.com> | |

25 | * Converted superio_init() to be a PCI_FIXUP_FINAL callee. | |

30 | /* NOTES: | |
31 | * | |
32 | * Function 0 is an IDE controller. It is identical to a PC87415 IDE | |
33 | * controller (and identifies itself as such). | |
34 | * | |
35 | * Function 1 is a "Legacy I/O" controller. Under this function is a | |
36 | * whole mess of legacy I/O peripherals. Of course, HP hasn't enabled | |
37 | * all the functionality in hardware, but the following is available: | |
38 | * | |
39 | * Two 16550A compatible serial controllers | |
40 | * An IEEE 1284 compatible parallel port | |
41 | * A floppy disk controller | |
42 | * | |
43 | * Function 2 is a USB controller. | |
44 | * | |
45 | * We must be incredibly careful during initialization. Since all | |
46 | * interrupts are routed through function 1 (which is not allowed by | |
47 | * the PCI spec), we need to program the PICs on the legacy I/O port | |
48 | * *before* we attempt to set up IDE and USB. @#$!& | |
49 | * | |
50 | * According to HP, devices are only enabled by firmware if they have | |
51 | * a physical device connected. | |
52 | * | |
53 | * Configuration register bits: | |
54 | * 0x5A: FDC, SP1, IDE1, SP2, IDE2, PAR, Reserved, P92 | |
55 | * 0x5B: RTC, 8259, 8254, DMA1, DMA2, KBC, P61, APM | |
56 | * | |
