2008-01-26ide: make remaining built-in only IDE host drivers modular (take 2)Bartlomiej Zolnierkiewicz
* Make remaining built-in only IDE host drivers modular, add ide-scan-pci.c file for probing PCI host drivers registered with IDE core (special case for built-in IDE and CONFIG_IDEPCI_PCIBUS_ORDER=y) and then take care of the ordering in which all IDE host drivers are probed when IDE is built-in during link time. * Move probing of gayle, falconide, macide, q40ide and buddha (m68k arch specific) host drivers, before PCI ones (no PCI on m68k), ide-cris (cris arch specific), cmd640 (x86 arch specific) and pmac (ppc arch specific). * Move probing of ide-cris (cris arch specific) host driver before cmd640 (x86 arch specific). * Move probing of mpc8xx (ppc specific) host driver before ide-pnp (depends on ISA and none of ppc platform that use mpc8xx supports ISA) and ide-h8300 (h8300 arch specific). * Add "probe_vlb" kernel parameter to cmd640 host driver and update Documentation/ide.txt accordingly. * Make IDE_ARM config option visible so it can also be disabled if needed. * Remove bogus comment from ide.c while at it. v2: * Fix two issues spotted by Sergei: - replace ENOMEM error value by ENOENT in ide-h8300 host driver - fix MODULE_PARM_DESC() in cmd640 host driver Cc: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: Mikael Starvik <starvik@axis.com> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Roman Zippel <zippel@linux-m68k.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2007-10-20qd65xx: remove pointless qd_{read,write}_reg() (take 2)Bartlomiej Zolnierkiewicz
These functions are atomic so locking is pointless (noticed by Sergei). v2: We can now just use local_irq_save/restore() in qd_testreg() (noticed by Jeff).

2007-10-20qd65xx: fix deadlock on error handlingBartlomiej Zolnierkiewicz
Stop abusing ide_lock lock (switch to a private locking). Fixes same issue as fixed by Alan Cox in atiixp host driver with commit 6c5f8cc33eb2e10b6ab788bbe259fc142a068627.

2007-10-20ide: add ide_device_add()Bartlomiej Zolnierkiewicz
* Add ide_device_add() helper and convert host drivers to use it instead of open-coded variants. * Make ide_pci_setup_ports() and do_ide_setup_pci_device() take 'u8 *idx' argument instead of 'ata_index_t *index'. * Remove no longer needed ata_index_t. * Unexport probe_hwif_init() and make it static. * Unexport ide_proc_register_port(). There should be no functionality changes caused by this patch (sgiioc4.c: ide_proc_register_port() requires hwif->present to be set and it won't be set if probe_hwif_init() fails).

2007-10-11ide: add ide_set{_max}_pio() (take 4)Bartlomiej Zolnierkiewicz
* Add IDE_HFLAG_ABUSE_{PREFETCH,FAST_DEVSEL,DMA_MODES} flags and set them in ht6560, cmd640, cmd64x and sc1200 host drivers. * Add set_pio_mode_abuse() for checking if host driver has a non-standard ->tuneproc() implementation and use it in do_special(). * Add ide_set_pio() for setting PIO mode (it uses hwif->pio_mask to find the maximum PIO mode supported by the host), also add ide_set_max_pio() wrapper for ide_set_pio() to use for auto-tuning. Convert users of ->tuneproc to use ide_set{_max}_pio() where possible. This leaves only do_special(), set_using_pio(), ide_hwif_restore() and ide_set_pio() as a direct users of ->tuneproc. * Remove no longer needed ide_get_best_pio_mode() calls and printk-s reporting PIO mode selected from ->tuneproc implementations. * Rename ->tuneproc hook to ->set_pio_mode and make 'pio' argument const. * Remove stale comment from ide_config_drive_speed(). v2: * Fix "ata_" prefix (Noticed by Jeff). v3: * Minor cleanups/fixups per Sergei's suggestions. v4: * Fix compile problem in drivers/ide/pci/cmd640.c (Noticed by Andrew Morton). * Improve some ->set_pio_mode comments.

* Add ide_pio_cycle_time() helper. * Use it in ali14xx/ht6560b/qd65xx/cmd64{0,x}/sl82c105 and pmac host drivers (previously cycle time given by the device was only used for "pio" == 255). * Remove no longer needed ide_pio_data_t.cycle_time field. v2: * Fix "ata_" prefix (Noticed by Jeff).

2007-07-08qd65xx: fix PIO mode selectionBartlomiej Zolnierkiewicz
PIO4 is a maximum PIO mode supported by a driver. Using "255" as a max_mode argument to ide_get_best_pio_mode() could result in wrong timings being used by a driver (for "pio" equal to 5) or OOPS (for "pio" values > 5 && < 255).

2007-05-10ide: add ide_proc_register_port()Bartlomiej Zolnierkiewicz
* create_proc_ide_interfaces() tries to add /proc entries for every probed and initialized IDE port, replace it by ide_proc_register_port() which does it only for the given port (also rename destroy_proc_ide_interface() to ide_proc_unregister_port() for consistency) * convert {create,destroy}_proc_ide_interface[s]() users to use new functions * pmac driver depended on proc_ide_create() to add /proc port entries, fix it * au1xxx-ide, swarm and cs5520 drivers depended indirectly on ide-generic driver (CONFIG_IDE_GENERIC=y) to add port /proc entries, fix them * there is now no need to add /proc entries for IDE ports in proc_ide_create() so don't do it * proc_ide_create() needs now to be called before drivers are probed - fix it, while at it make proc_ide_create() create /proc "ide" directory Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2007-03-03ide: make legacy IDE VLB modules check for the "probe" kernel params (v2)Bartlomiej Zolnierkiewicz
Legacy IDE VLB host drivers didn't check for "probe" options when compiled as modules, which was obviously wrong as we don't want module to poke at random I/O ports by simply loading it. Fix it by adding "probe" module param to legacy IDE VLB host drivers. v2: * don't obsolete old "ide0=dtc2278/ht6560b/qd65xx/ali14xx/umc8672" IDE driver options yet (per Alan Cox's request) and enhance documentation Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

"idex=serialize", "hdx=noautotune" and "hdx=autotune" are still available so there is no funcionality loss caused by this patch. v2: * fix CONFIG_BLK_DEV_4DRIVES=y build broken by version 1 of the patch [ /me wearing brown paper bag ] Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
