   (after a short discussion with tom rini, we're going to ignore any 
previous patch submissions of mine WRT microcode patches and start 
fresh.  first trivial patch, just to start things off.)

   purpose of patch:

   1) adds a relocation pointer to smc_uart_t
   2) redeclares reserved chunks in structures to be in terms of a
      standard char array, rather than the hideous combination of uint,
      ushort, and so on.  (a purely aesthetic fix, admittedly.)

more patches to follow shortly.
