 1.27  07-Oct-2013  jakllsch Use the universal pciide_detach() for detach function of all remaining
pciide-core drivers, except pciide at pnpbios which isn't actually PCI.
 1.26  31-Jul-2012  bouyer branches: 1.26.2; 1.26.4;
Apply back changes that were reverted on Jul 24 and Jul 26 (general ata/wdc
cleanup and SATA PMP support), now that I'm back to fix the fallouts.
 1.25  26-Jul-2012  jakllsch Revert, with intention of restoring in a less invasive way, the SATA Port
Multiplier code.

ok christos@
 1.24  24-Jul-2012  jakllsch Revert dsl@'s changes of Sun, 15 Jul 2012 10:55:35 +0000 and
Sun, 15 Jul 2012 10:56:50 +0000, excepting the kernel version bump.
First step in reverting regressions to ata(4) subsystem during the addition of
port multiplier support.
 1.23  15-Jul-2012  dsl Some namespace protection (and add greppablity).
Prefix the DRIVE_ and DRIVET_ constants from atavar.h with ATA_.
Don't use an enum for drive_type - you don't know how big it will be.
Move driver_type to avoid implicit structure padding (esp on arm).
This change is purely lexical and mechanical.

Update to 6.99.9 - this wasn't done when the SATA PMP changes
were made - I'm sure they warranted a bump.
 1.22  02-Jul-2012  bouyer Add sata Port MultiPlier (PMP) support to the ata bus layer,
as described in
http://mail-index.netbsd.org/tech-kern/2012/06/23/msg013442.html
PMP support in integrated to the atabus layer.
struct ata_channel's ch_drive[] is not dynamically allocated, and ch_ndrive
(renamed to ch_ndrives) closely reflects the size of the ch_drive[] array.
Add helper functions atabus_alloc_drives() and atabus_free_drives()
to manage ch_drive[]/ch_ndrives.
Add wdc_maxdrives to struct wdc_softc so that bus front-end can specify
how much drive they really support (master/slave or single).
ata_reset_drive() callback gains a uint32_t *sigp argument which,
when not NULL, will contain the signature of the device being reset.
While there, some cosmetic changes:
- added a drive_type enum to ata_drive_datas, and stop encoding the
probed drive type in drive_flags (we were out of drive flags anyway).
- rename DRIVE_ATAPIST to DRIVE_ATAPIDSCW to better reflect what this
really is
- remove ata_channel->ata_drives, it's redundant with the pointer in
ata_drive_datas
- factor out the interpretation of SATA signatures in sata_interpet_sig()

propagate these changes to the ATA HBA drivers, and add support for PMP
to ahcisata(4) and siisata(4).

Thanks to:
- Protocase (http://www.protocase.com/) which provided a system
with lots of controllers, SATA PMP and drive slots
- Conservation Genomics Laboratory, Department of Biology, New Mexico State
University for hosting the above system
- Brook Milligan, who set up remote access and has been very responsive
when SATA cable move was needed
 1.21  04-Apr-2011  dyoung branches: 1.21.4;
Neither pci_dma64_available(), pci_probe_device(), pci_mapreg_map(9),
pci_find_rom(), pci_intr_map(9), pci_enumerate_bus(), nor the match
predicate passed to pciide_compat_intr_establish() should ever modify
their pci_attach_args argument, so make their pci_attach_args arguments
const and deal with the fallout throughout the kernel.

For the most part, these changes add a 'const' where there was no
'const' before, however, some drivers and MD code used to modify
pci_attach_args. Now those drivers either copy their pci_attach_args
and modify the copy, or refrain from modifying pci_attach_args:

Xen: according to Manuel Bouyer, writing to pci_attach_args in
pci_intr_map() was a leftover from Xen 2. Probably a bug. I
stopped writing it. I have not tested this change.

siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args.
Probably a bug. I use a temporary variable. I have not tested this
change.

slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args.
Probably a bug. Use a local pci_attach_args. I have not tested
this change.

viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the
caller's pci_attach_args. Probably a bug. Make a local copy of the
caller's pci_attach_args and modify the copy. I have not tested
this change.

While I'm here, make pci_mapreg_submap() static.

With these changes in place, I have tested the compilation of these

 1.20  05-Nov-2010  jakllsch branches: 1.20.2;
Pave the way for detachment of pciide(4)-family ATA controllers.
 1.19  14-Mar-2009  dsl branches: 1.19.2; 1.19.4;
Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
 1.18  18-Mar-2008  cube branches: 1.18.4; 1.18.12; 1.18.18;
Split device_t and softc for ATA devices, as well as wd(4). Other
cosmetic changes where appropriate.
 1.17  24-Oct-2007  xtraeme branches: 1.17.12; 1.17.16;
- Add support for the ServerWorks HT-1000 IDE Controller in rccide.
- Add support for another ServerWorks HT-1000 SATA Controller.

From OpenBSD.
 1.16  09-Feb-2007  ad branches: 1.16.18; 1.16.20; 1.16.24;
Merge newlock2 to head.
 1.15  16-Nov-2006  christos __unused removal on arguments; approved by core.
 1.14  12-Oct-2006  christos - sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386
 1.13  11-Dec-2005  christos branches: 1.13.20; 1.13.22;
merge ktrace-lwp.
 1.12  21-Aug-2004  thorpej branches: 1.12.12;
atastart() (called only at splbio(), and from interrupts) can change
drive_flags, to make sure all drive_flags manipulations are done at
splbio().
 1.11  20-Aug-2004  thorpej Move most of wdc_softc into a new atac_softc structure that contains
info common to all types of ATA controllers.
 1.10  19-Aug-2004  thorpej - 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.)
 1.9  14-Aug-2004  thorpej - 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.
 1.8  13-Aug-2004  thorpej Don't bother with bits that tell of the presence of optional callbacks;
just check the function pointers for NULL.
 1.7  03-Jan-2004  thorpej branches: 1.7.4;
More wdc_channel structure member namespace cleanup:
- channel -> ch_channel
- wdc -> ch_wdc
 1.6  03-Jan-2004  thorpej Rename "struct channel_softc" to "struct wdc_channel".
 1.5  14-Dec-2003  thorpej Liberally apply "static", and wrap a line.
 1.4  02-Dec-2003  bouyer Use a different interrupt routine for the CSB6. The CSB6 doens't
assert IDEDMA_CTL_INTR for non-DMA commands.
It would be nice to have a way to know if the interrupt was for us or not at
this point, but for now let wdcintr() deal with it.
Problem reported and patch tested by Martti Kuparinen.
 1.3  27-Nov-2003  fvdl 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).
 1.2  07-Nov-2003  enami Sync with sys/dev/pci/pcidevs change (ProductID 0x0213 was renamed
to CSB6_RAID from CSB6_IDE). And exclude the device of RAID subclass
(i.e., match IDE subclass only).
 1.1  04-Nov-2003  mycroft Re-add ServerWorks IDE support, as "rccide". Note: this is untested, as I no
longer have a ServerWorks-based motherboard.

 1.26.2.1  09-Oct-2012  bouyer Support transfers of up to MACHINE_MAXPHYS in all pciide variants, and ahci.
wd(4) limits its maxphys depending on the drives's capability (64k sectors
for LBA48, 256 sectors for LBA and 128 sectors for older devices).

I assumed all pciide controllers could do MACHINE_MAXPHYS transfers, but
this may not be true. The capabilities of each controller variants should be
looked at more closely.
