Hi,
Is the question strictly related to this platform not implementing the mentioned errata (for which a platform change can be emitted)? Or is it more generally that those "missing errata warnings" are not printed in release mode? Assuming the latter, it looks to me it is the integrator mistake to not include the appropriate mitigations at development phase (hence while using debug mode for building TF-A). Then when the device is deployed (hence most often built for release mode), if this message is printed it is an indication for a malicious agent that such attack vector through mis-implemented errata is possible. So the consequence is possibly even worst than just "missing" to include the errata.
Other TF-Aers (Bipin?) may have other opinions?
Regards, Olivier.

Hello! If TF-A for Marvell Armada 3720 platform is compiled in debug mode then at runtime it prints following warning messages:
WARNING: BL1: cortex_a53: CPU workaround for 855873 was missing! WARNING: BL1: cortex_a53: CPU workaround for 1530924 was missing!
These lines are not printed in non-debug mode. It is an issue? -- TF-A mailing list TF-A@lists.trustedfirmware.org https://lists.trustedfirmware.org/mailman/listinfo/tf-a
