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:
