 * arch/arm/include/asm/ecard.h
 * definitions for expansion cards
 * This is a new system as from Linux 1.2.3
 * Changelog:
 *  11-12-1996    RMK   Further minor improvements
 *  12-09-1997    RMK   Added interrupt enable/disable for card level
 * Reference: Acorns Risc OS 3 Programmers Reference Manuals.
