     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.
