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.
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
46 /* Recognized load pages (by common convention). */
