32/* Page macros
33
34   The first GDB port requires flags in its remote memory access commands to
35   distinguish between data/prog space.  Hopefully we can make this go away
36   eventually.  Stuff the page in the upper bits of a 32-bit address, since
37   the c5x family only uses 16 or 23 bits.
38
39   c2x, c5x and most c54x devices have 16-bit addresses, but the c548 has
40   23-bit program addresses.  Make sure the page flags don't interfere.
41   These flags are used by GDB to identify the destination page for
42   addresses.
