thorpej 335b799580 atastart() (called only at splbio(), and from interrupts) can change 
drive_flags, to make sure all drive_flags manipulations are done at
splbio().

thorpej 9cc521a148 Move most of wdc_softc into a new atac_softc structure that contains 
info common to all types of ATA controllers.

thorpej 1600c8b8cd - Add and use a CHAN_TO_WDC() macro to get the wdc_softc from an 
ata_channel.
- Add and use a CHAN_TO_WDC_REGS() macro to get the wdc_regs from an
  ata_channel.
- Add and use a CHAN_TO_PCIIDE() macro to get the pciide_softc from an
  ata_channel.
- Add and use a CHAN_TO_PCHAN() macro to get the pciide_channel from an
  ata_channel.  (This one just hides a cast, and is really just for
  consistency with the others.)

thorpej 4b51cecfc2 - Split the register handles out of struct wdc_channel into a separate 
wdc_regs structure, and array of which (indexed per channel) is pointed
  to by struct wdc_softc.
- Move the resulting wdc_channel structure to atavar.h and rename it to
  ata_channel.  Rename the corresponding flags.
- Add a "ch_ndrive" member to struct ata_channel, which indicates the
  maximum number of drives that can be present on the channel.  For now,
  this is always 2.  Add an ATA_MAXDRIVES constant that places an upper
  limit on this value, also currently 2.

thorpej ab20886f7b Don't bother with bits that tell of the presence of optional callbacks; 
just check the function pointers for NULL.

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
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.

thorpej 36e9866d7b Cosmetic changes: 
- Use static to unexport symbols that don't need to be exported.
- ANSI'ify.
- Some whitespace nits.

bouyer 9d02ccdbdf Split pciide in per-chip family driver, as proposed in 
http://mail-index.netbsd.org/tech-kern/2003/09/25/0007.html
We now have:
acardide*       at pci? dev ? function ?        # Acard IDE controllers
aceride*        at pci? dev ? function ?        # Acer Lab IDE controllers
cmdide*         at pci? dev ? function ?        # CMD tech IDE controllers
cypide*         at pci? dev ? function ?        # Cypress IDE controllers
hptide*         at pci? dev ? function ?        # Triones/HighPoint IDE controllers
optiide*        at pci? dev ? function ?        # Opti IDE controllers
piixide*        at pci? dev ? function ?        # Intel IDE controllers
pdcide*         at pci? dev ? function ?        # Promise IDE controllers
siside*         at pci? dev ? function ?        # SiS IDE controllers
slide*          at pci? dev ? function ?        # Symphony Labs IDE controllers
viaide*         at pci? dev ? function ?        # VIA/AMD/Nvidia IDE controllers
pciide*         at pci? dev ? function ? flags 0x0000   # GENERIC pciide driver

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