Add a PCI front-end to esp(4) allowing it to support AMD Am53C974 and
replace amd(4) with the former in the amd64, i386 and pc98 GENERIC kernel
configuration files. Besides duplicating functionality, amd(4), which
previously also supported the AMD Am53C974, unlike esp(4) is no longer
maintained and has accumulated enough bit rot over time to always cause
a panic during boot as long as at least one target is attached to it
(see PR 124667).

Add a "kern.features.ata_cam" sysctl in the kernel when the ATA_CAM kernel
option is defined. This sysctl can be queried by feature_present(3).

Query for this feature in /sbin/atacontrol and /usr/sbin/burncd.
If these utilities detect that ATA_CAM is enabled, then these utilities
will error out. These utilities are compatible with the old ATA
driver, but are incomptible with the new ATA_CAM driver. By erroring out,
we give end-users an idea as to what remedies to use, and reduce the need for them
to file PR's. For atacontrol, camcontrol must be used instead,
and for burncd, alternative utilties from the ports collection must be used
such as sysutils/cdrtools.

In future, maybe someone can re-write burncd to work with ATA_CAM,
but at least for now, we give a somewhat useful error message to end users.

Improve output for controllers that doesn't report SATA speed.

MFp4:
Introduce ATA_CAM kernel option, turning ata(4) controller drivers into
cam(4) interface modules. When enabled, this options deprecates all ata(4)
peripheral drivers (ad, acd, ...) and interfaces and allows cam(4) drivers
(ada, cd, ...) and interfaces to be natively used instead.

As side effect of this, ata(4) mode setting code was completely rewritten
to make controller API more strict and permit above change. While doing
this, SATA revision was separated from PATA mode. It allows DMA-incapable
SATA devices to operate and makes hw.ata.atapi_dma tunable work again.

Also allow ata(4) controller drivers (except some specific or broken ones)
to handle larger data transfers. Previous constraint of 64K was artificial
and is not really required by PCI ATA BM specification or hardware.

Drop USB mass storage devices support from ata(4). It is out of the build as
long as I remember, and completely superseded by better maintained umass(4).
It's main idea was to optionally avoid CAM dependency for such devices, but
with move ATA to CAM, it is not actual any more.

Fix for a bug I introduced when I cleaned up atacontrol: Don't terminate
if we are listing devices, a controller might legitimately not be there.

Submitted by: "Andrey V. Elsukov" <bu7cher@yandex.ru>

Add a "spindown" facility to ata-disks: If no requests have been received
for a configurable number of seconds, spin the disk down. Spin it back
up on the next request.

Notice that the timeout is only armed by a request, so to spin down a
disk you may have to do:

atacontrol spindown ad10 5
dd if=/dev/ad10 of=/dev/null count=1

To disable spindown, set timeout to zero:

atacontrol spindown ad10 0

In order to debug any trouble caused, this code is somewhat noisy on the
console.

Enabling spindown on a disk containing / or /var/log/messages is not
going to do anything sensible.

Spinning a disk up and down all the time will wear it out, use sensibly.

GEOM doesn't allow WR access.

Print the rigth argv string on error (too much c&p)..

Fixed markup from the previous revision.

Reflect the new usage.

Change the way ioctls are issue to ATA.
The most prominent part is that its now possible to issue ata_requests
directly to say acd0, instead of going through the cumbersome /dev/ata
device.

This is the much rumoured ATA mkIII update that I've been working on.

o ATA is now fully newbus'd and split into modules.
This means that on a modern system you just load "atapci and ata"
to get the base support, and then one or more of the device
subdrivers "atadisk atapicd atapifd atapist ataraid".
All can be loaded/unloaded anytime, but for obvious reasons you
dont want to unload atadisk when you have mounted filesystems.

o The device identify part of the probe has been rewritten to fix
the problems with odd devices the old had, and to try to remove
so of the long delays some HW could provoke. Also probing is done
without the need for interrupts, making earlier probing possible.

o SATA devices can be hot inserted/removed and devices will be created/
removed in /dev accordingly.
NOTE: only supported on controllers that has this feature:
Promise and Silicon Image for now.
On other controllers the usual atacontrol detach/attach dance is
still needed.

o Support for "atomic" composite ATA requests used for RAID.

o ATA RAID support has been rewritten and and now supports these
metadata formats:
"Adaptec HostRAID"
"Highpoint V2 RocketRAID"
"Highpoint V3 RocketRAID"
"Intel MatrixRAID"
"Integrated Technology Express"
"LSILogic V2 MegaRAID"
"LSILogic V3 MegaRAID"
"Promise FastTrak"
"Silicon Image Medley"
"FreeBSD PseudoRAID"

o Update the ioctl API to match new RAID levels etc.

o Update atacontrol to know about the new RAID levels etc
NOTE: you need to recompile atacontrol with the new sys/ata.h,
make world will take care of that.
NOTE2: that rebuild is done differently from the old system as
the rebuild is now done piggybacked on read requests to the
array, so atacontrol simply starts a background "dd" to rebuild
the array.

o The reinit code has been worked over to be much more robust.

o The timeout code has been overhauled for races.

o Support of new chipsets.

o Lots of fixes for bugs found while doing the modulerization and
reviewing the old code.

Missing or changed features from current ATA:

o atapi-cd no longer has support for ATAPI changers. Todays its
much cheaper and alot faster to copy those CD images to disk
and serve them from there. Besides they dont seem to be made
anymore, maybe for that exact reason.

o ATA RAID can only read metadata from all the above metadata formats,
not write all of them (Promise and Highpoint V2 so far). This means
that arrays can be picked up from the BIOS, but they cannot be
created from FreeBSD. There is more to it than just the missing
write metadata support, those formats are not unique to a given
controller like Promise and Highpoint formats, instead they exist
for several types, and even worse, some controllers can have
different formats and its impossible to tell which one.
The outcome is that we cannot reliably create the metadata of those
formats and be sure the controller BIOS will understand it.
However write support is needed to update/fail/rebuild the arrays
properly so it sits fairly high on the TODO list.

o So far atapicam is not supported with these changes. When/if this
will change is up to the maintainer of atapi-cam so go there for
questions.
