It is no longer needed to set hwif->mmio flag to tell IDE layer to not
manage resources so cleanup host drivers that used hwif->mmio flag only
for this purpose.

Ditto for ide_legacy_init_one().

* Remove 'struct pci_dev *dev' argument from ide_hwif_setup_dma().

* Un-static ide_hwif_setup_dma() and add CONFIG_BLK_DEV_IDEDMA_PCI=n version.

* Add 'const struct ide_port_info *d' argument to ide_device_add[_all]().

* Factor out generic ports init from ide_pci_setup_ports() to ide_init_port(),
  move it to ide-probe.c and call it in in ide_device_add_all() instead of
  ide_pci_setup_ports().

* Move ->mate setup to ide_device_add_all() from ide_port_init().

* Add IDE_HFLAG_NO_AUTOTUNE host flag for host drivers that don't enable
  ->autotune currently.

* Setup hwif->chipset in ide_init_port() but iff pi->chipset is set
  (to not override setup done by ide_hwif_configure()).

* Add ETRAX host handling to ide_device_add_all().

* cmd640.c: set IDE_HFLAG_ABUSE_* also for CONFIG_BLK_DEV_CMD640_ENHANCED=n.

* pmac.c: make pmac_ide_setup_dma() return an error value and move DMA masks
  setup to pmac_ide_setup_device().

* Add 'struct ide_port_info' instances to legacy host drivers, pass them to
  ide_device_add() calls and then remove open-coded ports initialization.

* 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

* Add mpc8xx_ide_probe() to mpc8xx.c and call it from probe_for_hwifs().

* Convert ide_arm, ide-cris, ide-h8300, ide-pnp, buddha, falconide, gayle,
  macide, q40ide, cmd640 and mpc8xx host drivers to use ide_device_add().

  This removes dependency on ide_generic for these drivers so update
  ide/Kconfig accordingly.

v2:
* ide_arm build fix (s/ide_device_idx/ide_device_add/)

* Remove ide_init_port_data() call from ide_arm_init() and move
  ide_arm_init() call from init_ide_data() to ide_init().

This patch is a preparation for the future changes (and as a side-effect
makes obsolete "idex=io[,ctl[,irq]]" kernel parameters work for ide_arm).

* Rename init_hwif_data() to ide_init_port_data() and export it.

* For all users of ide_register_hw() with 'initializing' argument set
  hwif->present and hwif->hold are always zero so convert these host
  drivers to use ide_find_port()+ide_init_port_data()+ide_init_port_hw()
  instead (also no need for init_hwif_default() call since the setup
  done by it gets over-ridden by ide_init_port_hw() call).

* Drop 'initializing' argument from ide_register_hw().

* Convert ide-cs/delkin_cb host drivers to use ide_register_hw().

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!
