   8    The exceptions to this are the DUART, which can only generate IRQs,
   9    and the PLX SYSERR output, which can only generate FIQs.  We route
  10    both FIQs and IRQs through the generic IRQ handling system and the
  11    choice by the driver of which to use is basically an arbitrary one.  */
