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.
