            Bug ID: 484
           Summary: Write VHDL to expose CR and XER from Microwatt so
                    single-stepping is possible
           Product: Libre-SOC's first SoC
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: CONFIRMED
          Severity: major
          Priority: ---
         Component: Source Code
          Assignee: lkcl at lkcl.net

   NLnet milestone: ---

Additions need to be made to the microwatt vhdl code to allow CR and XER values
to be accessed through the DMI debug interface such that single-stepping
microwatt is possible. Then we will be able to compare libre-soc against it
much more easily, enabling us to find bugs faster.
