78281c53 | 1 | /* |
78281c53 ML |
2 | * Created 20 Oct 2004 by Mark Lord |
3 | * | |
4 | * Basic support for Delkin/ASKA/Workbit Cardbus CompactFlash adapter | |
5 | * | |
6 | * Modeled after the 16-bit PCMCIA driver: ide-cs.c | |
7 | * | |
8 | * This is slightly peculiar, in that it is a PCI driver, | |
9 | * but is NOT an IDE PCI driver -- the IDE layer does not directly | |
10 | * support hot insertion/removal of PCI interfaces, so this driver | |
11 | * is unable to use the IDE PCI interfaces. Instead, it uses the | |
12 | * same interfaces as the ide-cs (PCMCIA) driver uses. | |
13 | * On the plus side, the driver is also smaller/simpler this way. | |

29 | * No chip documentation has yet been found, | |
30 | * so these configuration values were pulled from | |
31 | * a running Win98 system using "debug". | |
32 | * This gives around 3MByte/second read performance, | |
33 | * which is about 2/3 of what the chip is capable of. | |
34 | * | |
35 | * There is also a 4KByte mmio region on the card, | |
36 | * but its purpose has yet to be reverse-engineered. | |
