Thanks Kathleen.
Hi All,
The change related to migrating Hafnium CI to using the standard FFA_CONSOLE_LOG [1] is merged.
Kathleen is now preparing changes to deprecate the former proprietary HF_DEBUG_LOG ABI in Hafnium [2] and TF-a-tests.
As this can lead to breaking downstream platforms, please provide feedback if you disagree with the approach.
Thanks, Olivier.

Hi,
With the introduction of FFA_CONSOLE_LOG ABI [1], we are intending to replace and remove support for HF_DEBUG_LOG.
This proposal is in review in the following stages: 1) Remove the dependency of hftest VMs on HF_DEBUG_LOG and move to FFA_CONSOLE_LOG [2] 2) Remove the support for HF_DEBUG_LOG (i.e. api_debug_log) from hafnium project. [3]
The adoption of FFA_CONSOLE_LOG will allow us to make use of its ability to log multiple characters at a time, as opposed to HF_DEBUG_LOG which writes one character at a time. This improvement will be enabled in a future patch. Also, should [3] be adopted, we will make accompanying changes to tf-a-tests Cactus-based tests.
We want to know if there are any concerns about removing support for HF_DEBUG_LOG at this time as we realize other downstream SPs may rely on its support.
Thank you, Kathleen Capella
