This allows to gain access to devices spending long time in WFI without
the need for a reset, at the expense of possible long waiting times.
Using Reset means loosing the device runtime context.
- On probe, read CTR for cache presence and minimum line length
- Make D-Cache clean a function
- Clean before memory reads
- Clean and invalidate before memory writes
- Flush all I-Cache before resume
This adds a new function to the internal target interface
to allow the target to get control before reset is complete
so that it can do any additional work. On this target there
is a proprietary internal bit that has to be reset in some
cases to allow the core to continue operating.
The new function returns a stop reason which must be translated in gdb server.
In the case of a watchpoint hit, the address is returned by a pointer parameter.
Simplify the extenal interface for set/clear breaki-/watchpoints.
