| 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. | |
