  35.    The first GDB port requires flags in its remote memory access commands to
  36.    distinguish between data/prog space.  Hopefully we can make this go away
  37.    eventually.  Stuff the page in the upper bits of a 32-bit address, since
  38.    the c5x family only uses 16 or 23 bits.
  39.  
  40.    c2x, c5x and most c54x devices have 16-bit addresses, but the c548 has
  41.    23-bit program addresses.  Make sure the page flags don't interfere.
  42.    These flags are used by GDB to identify the destination page for
  43.    addresses.
