This is the IDE driver for the on-board IDE interface on some m68k
- Macintosh models. It supports both the `Quadra style' (used in
- Quadra/ Centris 630 and Performa 588 models) and `Powerbook style'
- (used in the Powerbook 150 and 190 models) IDE interface.
+ Macintosh models, namely Quadra/Centris 630, Performa 588 and

+ supported by this driver and requires BLK_DEV_PLATFORM or
