* linux/include/asm-arm26/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
* 18-05-2003 IM Adjusted for ARM26
* Reference: Acorns Risc OS 3 Programmers Reference Manuals.
