Extend the MemTxAttrs to include 'debug' flag. The flag can be used as general indicator that operation was triggered by the debugger.
Later in the patch series we set the debug=1 when issuing a memory access from the gdbstub or HMP commands. This patch is prerequisite to support debugging the encrypted guest. If we see request with debug=1 then we will need to use encryption APIs to access the guest memory. Cc: Alistair Francis <[email protected]> Cc: Peter Maydell <[email protected]> Cc: "Edgar E.
