Migrate many bus_alloc_resource() calls to bus_alloc_resource_anywhere().
Most calls to bus_alloc_resource() use "anywhere" as the range, with a given count. Migrate these to use the new bus_alloc_resource_anywhere() API.

Convert rman to use rman_res_t instead of u_long
Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of u_long.
Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.

- With the demise of !ATA_CAM, ATA_STATIC_ID is the only ata(4) related option left but actually consumed by ada(4), so move it to opt_ada.h and get rid of opt_ata.h. - Fix stand-alone build of atacore(4) by adding opt_cam.h. - Use __FBSDID. - Use DEVMETHOD_END. - Use NULL instead of 0 for pointers.

Remove all legacy ATA code parts, not used since options ATA_CAM enabled in most kernels before FreeBSD 9.0. Remove such modules and respective kernel options: atadisk, ataraid, atapicd, atapifd, atapist, atapicam. Remove the atacontrol utility and some man pages. Remove useless now options ATA_CAM.

Since ATA_CAM mode has no implemented support for serializing access to the different ATA channels, required for acard and pc98 ATA controllers, block access to second channels of both, hoping that one working channel is better then none. I have an idea how that support could be implemented, but I have no hardware to work on that.

Remove remnants of ATA_LOCKING uses in the ATA_CAM case and wrap it along with functions, SYSCTLs and tunables that are not used with ATA_CAM in #ifndef ATA_CAM, similar to the existing #ifdef'ed ATA_CAM code for the other way around. This makes it easier to understand which parts of ata(4) actually are used in the new world order and to later on remove the !ATA_CAM bits. It also makes it obvious that there is something fishy with the C-bus front-end as well as in the ATP850 support, as these used ATA_LOCKING which is defunct in the ATA_CAM case. When fixing the former, ATA_LOCKING probably needs to be brought back in some form or other.

DEVICE_PROBE(9) claims that we must not initialize softc on probe stage. Move channel softc initialization from ata_XXX_probe() to ata_XXX_attach().
Instead of calculating ata channel number as position in child device list, pass it's real number directly from controller probe routine using ivars. It is simpler and IMHO more correct.

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.

Move the PC98 specific geometry "gunk" to geom_pc98.c where it belongs. This also adds support for bigger disks on the controller I have access to, and maybe others if I understood the adhoc methods used on those.

Add support for the Promise command sequencer present on all modern Promise controllers (PDC203** PDC206**).
This also adds preliminary support for the Promise SX4/SX4000 but *only* as a "normal" Promise ATA controller (ATA RAID's are supported though but only RAID0, RAID1 and RAID0+1).
This cuts off yet another 5-8% of the command overhead on promise controllers, making them the fastest we have ever had support for.
Work is now continuing to add support for this in ATA RAID, to accellerate ATA RAID quite a bit on these controllers, and especially the SX4/SX4000 series as they have quite a few tricks in there..
This commit also adds a few fixes to the SATA code needed for proper support.

Use UMA instead of plain malloc for getting ATA request storage. This gives +10% performance on simple tests, so definitly worth it. A few percent more could be had by not using M_ZERO'd alloc's, but we then need to clear fields all over the place to be safe, and that was deemed not worth the trouble (and it makes life dangerous).

Overhaul of the timeout/reinit framework. This should clear up most of the leftovers from the old version that really doesn't work anymore.
Add a reset function for host-end of the ATA channel. This is needed for the SiI3112 in order to whack it back to reality if a device locks up the SATA interface (thereby preventing that we can reset the device). The result is that ATA now recovers from the timeouts that happens with the SiI3112A and more or less all disks based on old PATA electronics with a Marvell PATA->SATA converter. This includes lots of the popular SATA dongles and the WDC Raptor disks..

This is a major rework of the ATA driver (ATAng)
Restructure the way ATA/ATAPI commands are processed, use a common ata_request structure for both. This centralises the way requests are handled so locking is much easier to handle.
The driver is now layered much more cleanly to seperate the lowlevel HW access so it can be tailored to specific controllers without touching the upper layers. This is needed to support some of the newer semi-intelligent ATA controllers showing up.
The top level drivers (disk, ATAPI devices) are more or less still the same with just corrections to use the new interface.
Pull ATA out from under Gaint now that locking can be done in a sane way.
Add support for a the National Geode SC1100. Thanks to Soekris engineering for sponsoring a Soekris 4801 to make this support.
Fixed alot of small bugs in the chipset code for various chips now we are around in that corner anyways.

Second round of updates to the ATA driver.
Clean up the DMA interface too much unneeded stuff crept in with the busdma code back when.
Modify the ATA_IN* / ATA_OUT* macros so that resource and offset are gotten from a table. That allows for new chipsets that doesn't nessesarily have things ordered the good old way. This also removes the need for the wierd PC98 resource functions.
Tested on: i386, PC98, Alpha, Sparc64

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!

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..
