  fmc-trivial
  ===========
  
  The simple module fmc-trivial is just a simple client that registers an
  interrupt handler. I used it to verify the basic mechanism of the FMC
  bus and how interrupts worked.
  
  The module implements the generic FMC parameters, so it can program a
  different gateware file in each card. The whole list of parameters it
  accepts are:
  
  `busid='
  `gateware='
       Generic parameters. See mezzanine.txt
  
  
  This driver is worth reading, in my opinion.
