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