  14  *  Changelog:
  15  *   01-10-1997 RMK             Created, READONLY version
  16  *   15-02-1998 RMK             READ/WRITE version
  17  *                              added DMA support and hardware definitions
  18  *   14-03-1998 RMK             Updated DMA support
  19  *                              Added terminator control
  20  *   15-04-1998 RMK             Only do PIO if FAS216 will allow it.
  21  *   27-06-1998 RMK             Changed asm/delay.h to linux/delay.h
  22  *   02-04-2000 RMK     0.0.3   Fixed NO_IRQ/NO_DMA problem, updated for new
  23  *                              error handling code.
