| 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.
