|
* Slot structures for PC-CARD interface.
|
|
* Each slot has a controller specific structure
|
|
* attached to it. A slot number allows
|
|
* mapping from the character device to the
|
|
* slot structure. This is separate to the
|
|
* controller slot number to allow multiple controllers
|
|
* to be accessed.
