+ * Find all installed expansion cards, and handle interrupts from them.
+ *
+ * Created from information from Acorns RiscOS3 PRMs
+ *
+ * 08-Dec-1996 RMK Added code for the 9'th expansion card - the ether
+ * podule slot.
+ * 06-May-1997 RMK Added blacklist for cards whose loader doesn't work.
+ * 12-Sep-1997 RMK Created new handling of interrupt enables/disables
+ * - cards can now register their own routine to control
+ * interrupts (recommended).
+ * 29-Sep-1997 RMK Expansion card interrupt hardware not being re-enabled
+ * on reset from Linux. (Caused cards not to respond
+ * under RiscOS without hard reset).
+ * 15-Feb-1998 RMK Added DMA support
+ * 12-Sep-1998 RMK Added EASI support
+ * 10-Jan-1999 RMK Run loaders in a simulated RISC OS environment.
+ * 17-Apr-1999 RMK Support for EASI Type C cycles.
