[Qemu-devel] [PATCH v5 1/7] hmp: Add flag for preconfig commands |
Date: |

From: "Dr. David Alan Gilbert" <address@hidden>
Add a flag to command definitions to allow them to be used in preconfig
and check it.
If users try to use commands that aren't available, tell them to use
the exit_preconfig comand we're adding in a few patches.
