13 *
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.
