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