      console: Add a console buffer · 9854a874
      Simon Glass authored
      
      It is useful to be able to record console output and provide console input
      via a buffer. This provides sandbox with the ability to run a command and
      check its output. If the console is set to silent then no visible output
      is generated.
      
      This also provides a means to fix the problem where tests produce unwanted
      output, such as errors or warnings. This can be confusing. We can instead
      set the console to silent and record this output. It can be checked later
      in the test if required.
      
      It is possible that this may prove useful for non-test situations. For
      example the console output may be suppressed for normal operations, but
      recorded and stored for access by the OS. That feature is not implemented
      at present.
