Firmware BMP with ENABLE_DEBUG=1 will print WARN and INFO as before.
PC-Hosted BMPwill alway print to stderr. Warn is printed unconditional,
INFO, GDB, TARGET, DONGLE and WIRE will print if their appropriate bit in
cl_debuglevel is set via the -v verbose command line argument.
INFO will go to stdout with -t or -l.
This is will make debugging earier if this does happen, rather than
dereferencing the null pointer (or passing it to memcpy, or worse).
blackmagic PR #475
The old code for 'fast' memory accesses using the AHB directly
has problems with data consitency. Until this can be resolved, I'm
removing the affected code.
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.
