      Report errata workaround status to console · 10bcd761
      Jeenu Viswambharan authored
      
      
      The errata reporting policy is as follows:
      
        - If an errata workaround is enabled:
      
          - If it applies (i.e. the CPU is affected by the errata), an INFO
            message is printed, confirming that the errata workaround has been
            applied.
      
          - If it does not apply, a VERBOSE message is printed, confirming
            that the errata workaround has been skipped.
      
        - If an errata workaround is not enabled, but would have applied had
          it been, a WARN message is printed, alerting that errata workaround
          is missing.
      
      The CPU errata messages are printed by both BL1 (primary CPU only) and
      runtime firmware on debug builds, once for each CPU/errata combination.
      
      Relevant output from Juno r1 console when ARM Trusted Firmware is built
      with PLAT=juno LOG_LEVEL=50 DEBUG=1:
