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. |
||
39 | |||
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 |
||
43 | addresses. |
