There are target methods for operating on hardware breakpoints / watchpoints.

target.to_insert_hw_break(watch)point . So depending on the target
specification the implementation is present.
A case in study would be procf implementations of hw breakpoints /
watchpoints with procfs . look at nto-procfs.c for the QNX Neutrino as a
case study of stuff.

You can also look at remote_insert_hw_breakpoint in remote.c . The
simulator must also have such an interface since the simulator is one more
target for gdb.
