jdolecek | move ata_queue_alloc(1) and ata_queue_free() calls to ata_channel_init()
and ata_channel_destroy() respectively, to make attachment code simpler,
and to make it easier to spot special queue manipulation like cmdide(4)

jdolecek | Merge support for SATA NCQ (Native Command Queueing) from jdolecek-ncq branch
ATA subsystem was changed to support several outstanding commands, and use
NCQ xfers if supported by both the controller and the disk, including NCQ
error recovery. Set NCQ high priority for BPRIO_TIMECRITICAL xfers
if supported. Added FUA support.
Done some work towards MP-safe, all ATA code tsleep()/wakeup() replaced
by condvars, and switched most code from spl* to mutexes (separate
wd(4) and ata channel lock).
Introduced new option WD_CHAOS_MONKEY to facilitate testing of error
handling, fixed several uncovered issues. Also fixed several problems
with kernel dump to wd(4) disk.
Tested with ahcisata(4), mvsata(4), siisata(4), piixide(4) on amd64,
with and without port multiplier, both disk and ATAPI devices; other
drivers and archs mechanically adjusted and compile-tested. NCQ is
supported for ahcisata(4) and siisata(4) for any controller, for
mvsata(4) only Gen IIe ones for now. Also enabled ATAPI support in
mvsata(4).
Thanks to Matt Thomas for initial ATA infrastructure patch, and
Jonathan A.Kollasch for siisata(4) NCQ changes and general testing.
Also fixes PR kern/43169 (wd(4)); and PR kern/11811, PR kern/47041,
PR kern/51979 (kernel dump)

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.

Multiplier code.

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

Change <machine/bus.h> to <sys/bus.h> throughout.
Split bus.h -> bus_{defs,funcs}.h.
Mark acorn32/bus.h obsolete.

chris | Fix EB7500ATX kernel to build again, mainly catching up on 6+ months of
changes elsewhere in the kernel:
* kernel_l1pt is now a global in pmap
* wdc no longer has dma/udma caps without the relevant options, however,
rside doesn't support dma/udma so don't set the options.
* also fix a device_t/softc split issue.
Perhaps I should add the kernel to the default build list for acorn32, to
avoid any other breakage. Although as the only person probably even
running NetBSD on an EB7500ATX system I'm not sure it's worthwhile.

Split device_t and softc for ATA devices, as well as wd(4). Other
cosmetic changes where appropriate.

bouyer | branches: 1.8.48; 1.8.50; 1.8.70; 1.8.74;
properly use ata_channel->ch_ndrive:
- initialize it properly in the bus front-ends (all 2, exept in wdc_pcmcia.c
for the "Sandisk CompactFlash Card" where it's set to 1)
- remplace hardcoded '2' by ata_channel->ch_ndrive in MI IDE drivers.

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

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.

thorpej | branches: 1.3.2;
Add the notion of "shadow registers" to the wdc driver. These shadow
registers are registers that overlap with others on many controllers, but
which may actually be distinct on some controllers. Right now, the two
shadows are:
- wd_status (usually overlaps wd_command)
- wd_features (usually overlaps wd_error)
Add a new helper function, wdc_init_shadow_regs(), used to initialize
the shadow register handles on controllers where they do actually overlap.

chris | Tidy up a few things:
Get rid of the static bus tag, instead move it into the softc.
Update to ThorpeJ's recent variable renaming for ATA things.
De-__P and KNF prototypes, also make attach and probe static.
Add RCSID.
Add a copyright for myself.

chris | First part of support for the eb7500atx board from simtec:
http://www.simtec.co.uk/products/EB7500ATX/
also available with RISC-OS as a RiscStation:
http://www.riscstation.co.uk/html/products.html
This is basic bootstrap with support for ide and networking, currently only
tested with booting from ABLE, and not RISC-OS.
I would have placed it into evbarm, but iomd doesn't appear to use the same
interrupt files as evbarm. I'll check it into here for now, until iomd
uses the common interrupt code.

reduce duplication of logic in individual drivers, and to actually work now
that more init is needed beyond the memset()
