/* 
 *  Linux IRQ interrupts definitions here.
 *	TBD not worth the effort to put duplicate bit defines in platform.h
 *
 *	Current IRQ implementation
 *
 *	1.  Current implementation does not support vectored 
 *	    interrupts.  support for this feature may be 
 *	    added later.
 *	2.  FIQs are ignored.  None are assigned.
 *	3.  All interrupts are assigned to IRQs.
 *	5.  IRQ numbers are same as interrupt bit numbers.
