The first GDB port requires flags in its remote memory access commands to
|
|
distinguish between data/prog space. Hopefully we can make this go away
|
|
eventually. Stuff the page in the upper bits of a 32-bit address, since
|
|
the c5x family only uses 16 or 23 bits.
|
|
|
|
c2x, c5x and most c54x devices have 16-bit addresses, but the c548 has
|
|
23-bit program addresses. Make sure the page flags don't interfere.
|
|
These flags are used by GDB to identify the destination page for
|
|
addresses.
