Søren Schmidt b301920c88 Revert the probe code change.
It helped those fake devices probe delays to go away, but as a side
effect it also made some not so conforming CD/DVD drives go away...

Søren Schmidt bb5bdd386e First round off updates/fixes to the ATA driver.
This moves all chipset specific code to a new file 'ata-chipset.c'.
Extensive use of tables and pointers to avoid having the same switch
on chipset type in several places, and to allow substituting various
functions for different HW arch needs.
Added PIO mode setup and all DMA modes.
Support for all known SiS chipsets. Thanks to Christoph Kukulies for
sponsoring a nice ASUS P4S8X SiS648 based board for this work!

Tested on:	i386, PC98, alpha and sparc64

Alfred Perlstein c11110eabe Fix crash dumps on ata and scsi.
To fix scsi, don't wait for ithreads if we're dumping, it makes the
debugger sad.

To fix ata, use what appears to be a polling method if we're dumping,
I stole this from tmm but added code to ensure that this change is
only in effect while dumping.

Søren Schmidt 15fa4bd593 Fix the 48bit access support for the older Promise 66/100 controllers, the
first attempt was wrong and could cause r/w timeouts.

Søren Schmidt 8ba4488cea Add support for the PC98 platform to the ATA driver.
This mostly consists of functionality to serialize accesses to
the two ATA channels (which can also be used to "fix" certain
PCI based controllers).
Add support for Acard controllers.
Enable the ATA driver in PC98 GENERIC, and add device hints.
Update man page with latest support.

The PC98 core team has kindly provided me with a PC98
machine that made this all possible, thanks to all that
contributed to that effort, without that this would
probably newer have been possible..

Thomas Quinot 9e3a06e150 In ata_reinit, when ata_getparam fails for a new device (indicating that
the device is not actually present), clear the corresponding bit in
the ch->devices bitmap. This resolves a panic that occurred with ATAPI/CAM
after an APM suspend/resume, when the ATA hardware would erroneously
report an extra ATAPI device.

Thomas Quinot e937fdbdcd Fill in missing parts of the ATAPI/CAM XPT: implement XPT_RESET_BUS
and XPT_RESET_DEV.

In order to properly handle reset requests whether they originate in the
ATA layer (atacontrol reinit) or from the CAM layer (camcontrol reset)
ata_reinit does not cause the SIM to be deallocated anymore. The SIM
is now unconditionnally created for each ATAPI bus.

This change may cause existing bus ids to change on some setups.

Søren Schmidt 85db7089ec Add support for creating/deleting ATA RAID's.
This completes the ATA RAID support, since all functions to manipulate
the RAID are accessible from FreeBSD, the BIOS on the ATA RAID cards
are only nessesary for booting.

I decided to allow for creation of ATA RAID's on any ATA controller, but
please keep in mind the restrictions on that. Due to the BIOS not
knowing what to do you can only boot from a RAID1 or the first disk
in a SPAN, if its not located on a "real" ATA RAID controller like
the Promise or Highpoint controllers.

Søren Schmidt 6f87be981b Major update of the ATA RAID code, part 3:
Add code to properly detach/attach disks that are part of a RAID.

Mark a disk that is attached on an ATA channel belonging to a
RAID as a spare disk that can be used for rebuilding failed RAID1's.

Add support for rebuilding failed RAID1's.

Several fixes to the detach/attach code.

For replacing a disk in a failed RAID1 do the following:

Find the controller channel# of the failed disk.

Exec 'atacontrol detach <channel#>' to free the disk from the system.

Replace the failed disk with a new one of at least the same size.
If your have your disks in drawers/enclosures this can be done with
the system still running.

Exec 'atacontrol attach <channel#>' to add the disk to the system and
mark it as a valid spare for rebuild.

Exec 'atacontrol rebuild <array#>'

The system will rebuild the array on the fly, the array can still
be used during this, although with slower performance.

Please let me know of any problems with this!

Søren Schmidt 6ddce9039b Major update of the ATA RAID code, part 1:
Overhaul of the attach/detach code and structures, there were some nasty
bugs in the old implementation. This made it possible to collapse the
ATA/ATAPI device control structures into one generic structure.

A note here, the kernel is NOT ready for detach of active devices,
it fails all over in random places, but for inactive devices it works.
However for ATA RAID this works, since the RAID abstration layer
insulates the buggy^H^H^H^H^H^Hfragile device subsystem from the
physical disks.

Proberly detect the RAID's from the BIOS, and mark critical RAID1
arrays as such, but continue if there is enough of the mirror left
to do so.

Properly fail arrays on a live system. For RAID0 that means return EIO,
and for RAID1 it means continue on the still working part of the mirror
if possible, else return EIO.
If the state changes, log this to the console.

Allow for Promise & Highpoint controllers/arrays to coexist on the
same machine. It is not possible to distribute arrays over different
makes of controllers though.

If Promise SuperSwap enclosures are used, signal disk state on the
status LED on the front.

Misc fixes that I had lying around for various minor bugs.
