bouyer 574dd00e11 If acknowledge "bogus" interrupts (that is, interrupts that have happened 
according to the controller-dependant registers while wdc was not waiting for
an interrupt). A reset can generate spurious interrupts (or even a flow of
spurious interrupts on the promise) that needs to be properly acknowledged.

thorpej a963286f8d More wdc_channel structure member namespace cleanup: 
- channel -> ch_channel
- wdc -> ch_wdc

thorpej 5bd80d8373 Rename "struct channel_softc" to "struct wdc_channel". 2004-01-03 01:50:52 +00:00
fvdl 6242a54566 There are some cards that map the ATA control and IDE DMA registers 
in a different fashion. Individually, they have the same functionality,
but their layout is different. An example of such a chipset is
the Promise 203xx.

To be able to deal with this, transform the cmd and dma bus_space handles
into an array of handles, each seperately created with bus_space_subregion.
The code generated by using the extra indirection shouldn't change much,
since the extra indirection is negated by having the offset calculation
already done in bus_space_subregion. E.g.

	bus_space_write_4(tag, handle, offset, value)

becomes

	bus_space_write_4(tag, handles[offset], 0, value)

Reviewed by Manuel Bouyer. Tested on wdc_isa, wdc_pcmcia, viaide, piixide (i386)
and on cmdide (sparc64).

fvdl 370056a0f6 Use the redefined Promise product ids. 2003-11-22 20:57:18 +00:00
bouyer 5741c101e5 Clear interrupts at end of attach, in case there is one pending. 
Avoid "bogus intr" messages when interrupts are enabled later.
Patch tested by myself and Chuck Silvers.

mycroft a480189bf8 Remove IDE_PCI_CLASS_OVERRIDE -- it wasn't actually used anywhere. In lieu of 
it, add a class/subclass check to drivers that do not (appear) to have a unique
ID for the IDE controller.  This includes aceride, cypide and optiide.

fvdl 91371415b1 Match the Promise FastTrak 378. 2003-10-22 11:32:40 +00:00
thorpej 36e9866d7b Cosmetic changes: 
- Use static to unexport symbols that don't need to be exported.
- ANSI'ify.
- Some whitespace nits.

serverworks driver not commited yet; there are still copyright issues about
it.
