by Shebu Varghese Kuriakose

Hi Gernot, Provisioning was added as a future roadmap item in anticipation of a PSA Provisioning Specification. The Specification (Factory or application specific) hasn't happened so far. There is no active work ongoing in TF-M around provisioning. TF-M using provisioned keys in CC-312 on MuscaB1 platform is available as an example. See details here<https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/lastSuccessfulBu…> under CC312 heading. In TrustedFirmware TSC, provisioning has been a discussion topic sometime back. Search for provisioning in the minutes below. https://github.com/microbuilder/certificate_chains/blob/master/rfc_tfm.md is an RFC that Kevin prepared during those discussions for TF-M devices to use certificate chain.

What provisioning functionality would we be talking here, is it provisioning as in "RoT provisioning", so more towards manufacturing as defined in the PSA security lifecycle, or provisioning when the device is in state "Secured", so more towards application specific-data? I would assume the latter, but couldn't find any more information on this subject. Any pointers would be highly appreciated.

Re: [TF-M] PSA documentation page

[RFC] Compiler-specific configurations and architecture registers

by Summer Qin

Hi, Even the ongoing HAL design abstracts all platform-specific operations, there are still some operations that need to be performed directly in TF-M, such as architecture-related operations. These operations are common for all platforms, such as: * generic assembler code for AAPCS based context management. * assign attributes to specific functions. These operations rely on compiler and architecture much instead of the platform. So, define a CORE-specific compiler configuration header file would be a straight requirement. With these unified headers, writing the architecture-specific code would be much safer because it won't involve hardcode compiler related changes. The minimal set of mandatory architecture registers is also planned to be defined. Here send out a mail to collect for the feedbacks - is it worthy of doing this to decouple the architecture from the platform, or we can just re-use the platform provided headers? Any comments are welcome:) Best Regards, Summer

Proposal to add sub-folders to collect documents under design_documents folder

by David Hu

Hi all, I'd like to propose to add sub-folders under docs/design_documents to collect the documents on the same topic. Currently, there are already 21 documents in total under docs/design_documents and the number may grow rapidly. It can be more clear if we can organize the documents on the same topic into a dedicated sub-folder under docs/design_documents. Please help review the patch set https://review.trustedfirmware.org/q/topic:%22design-doc-subdir%22+(status:… if the proposal sound interesting. I move dual-cpu and TF-M Profiles related documents to their dedicated folder respectively in the patches. Any comment is welcome! In current patches, the html pages are still put in the same level during Sphinx build. It is because design documents are grouped by document status, instead of document hierarchy. The html pages can be further organized as well if we switch to group html according to folder structures. Best regards, Hu Ziji

Ask for final review of symmetric based initial attestation design

by David Hu

Hi all, May I ask for a final round of review on symmetric initial attestation design document on https://review.trustedfirmware.org/c/trusted-firmware-m/+/3898? The document has been reviewed for a long time and received many valuable comments. Thanks a lot. If there is no further critical comment, I'd like to merge this design this Friday.
