Report errata workaround status to console 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.
