[v2,0/2] gdb invalid memory access handling improvements

Message

Nicholas Piggin March 17, 2025, 5:16 a.m. UTC

This adds .debug=1 attribute for GDB's phys mem access mode, adds
memory transaction error handling for it so it reports cannot access
memory instead of silent success, and silences warning logs for
invalid memory access coming from the debugger.

Changes since v1:
- Move phys_memory_rw_debug() into gdbstub/system.c and update patch
  changelog to match.

Thanks,
Nick
