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