 1.29  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.
 1.28  31-Jul-2012  bouyer branches: 1.28.2; 1.28.4;
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.
 1.27  26-Jul-2012  jakllsch Revert, with intention of restoring in a less invasive way, the SATA Port
Multiplier code.

ok christos@
 1.26  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.
 1.25  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.
 1.24  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
 1.23  08-Apr-2012  jakllsch As suggested in the previous commit, the overwrite of the pci_attach_args
is a bug. Although I have not tested on real hardware, Linux's
pata_sl82c105.c only looks at the revision of the PCI bridge.
 1.22  04-Apr-2011  dyoung branches: 1.22.4; 1.22.8;
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

 1.21  05-Nov-2010  jakllsch branches: 1.21.2;
Pave the way for detachment of pciide(4)-family ATA controllers.
 1.20  28-Apr-2008  martin branches: 1.20.20; 1.20.22;
Remove clause 3 and 4 from TNF licenses
 1.19  18-Mar-2008  cube branches: 1.19.2; 1.19.4;
Split device_t and softc for ATA devices, as well as wd(4). Other
cosmetic changes where appropriate.
 1.18  26-Apr-2007  garbled branches: 1.18.8; 1.18.24; 1.18.28;
Remove the PCIIDE_SLIDE_SETIRQA hack. Recent revalations have uncovered
the fact that it's useless.
 1.17  20-Mar-2007  garbled Put a small hack in slide.c disabled by default. PCIIDE_SLIDE_SETIRQA. This
sets IDE_IRQA in the IDE Control/Status Register. This is needed on prep
machines with Motorola RAVEN host bridges, as they wire up the ide device
oddly.
 1.16  09-Feb-2007  ad branches: 1.16.2; 1.16.6; 1.16.8; 1.16.10;
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  03-Sep-2006  christos branches: 1.13.2; 1.13.4;
add missing initializer
 1.12  11-Dec-2005  christos branches: 1.12.4; 1.12.8;
merge ktrace-lwp.
 1.11  24-May-2005  lukem branches: 1.11.2;
add __KERNEL_RCSID
 1.10  27-Feb-2005  perry nuke trailing whitespace
 1.9  21-Aug-2004  thorpej branches: 1.9.4; 1.9.6;
atastart() (called only at splbio(), and from interrupts) can change
drive_flags, to make sure all drive_flags manipulations are done at
splbio().
 1.8  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.
 1.7  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.)
 1.6  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.
 1.5  13-Aug-2004  thorpej Don't bother with bits that tell of the presence of optional callbacks;
just check the function pointers for NULL.
 1.4  03-Jan-2004  thorpej branches: 1.4.4;
More wdc_channel structure member namespace cleanup:
- channel -> ch_channel
- wdc -> ch_wdc
 1.3  03-Jan-2004  thorpej Rename "struct channel_softc" to "struct wdc_channel".
 1.2  11-Oct-2003  thorpej Cosmetic changes:
- Use static to unexport symbols that don't need to be exported.
- ANSI'ify.
- Some whitespace nits.
 1.1  08-Oct-2003  bouyer 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:

cmdide* at pci? dev ? function ? # CMD tech IDE controllers
cypide* at pci? dev ? function ? # Cypress IDE controllers

 1.28.2.1  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.
