  Log:
  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.
