Face it, drivers/ide/ is beyong saving, it has entered the software
engineering twilight zone that follows 'maintainable'.

Shifting a non-complex driver to libata with a few libata improvements
is not a difficult process. Figuring out the extra hooks and bits to
make it clean is the difficult bit. Each time another PATA horror is
supported by libata it becomes easy for other cards with that horror to
be moved over.

Also drivers/ide contains detailed support for things that just aren't
worth moving over - like SWDMA.

Once the core support is done then quite frankly I'll be able to port a
PATA driver to libata faster than sherlock holmes could deduce the
drivers/ide locking "rules" let alone fix them.
