| 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.
