Re: [TF-M] Technical Forum call - January 21

by Anton Komlev

Hello, The agenda for the forum: 1. Proposal for changes to the OpenCI job coverage 2. Proposal to reduce Doxygen coverage to the interfaces only 3. Ongoing open issues: * Musca-A platform deprecation * Arm Firmware Framework for M 1.1 Extensions Alpha specification Regards,, Anton From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Ken Liu via TF-M Sent: 20 January 2021 14:18 To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] Technical Forum call - January 21 Hi Anton, I would like to raise a discussion about doxygen usage. I think it is acceptable to apply doxygen usage in interfaces only if we want to keep alignment with CMSIS code since it applied doxygen result as reference manual; but for other logics, the doxygen is almost not used. Wondered how many users would generate reference manual from doxygen; or they just open an editor then start reading code from sources.

Couple of adjustment patches coming

by Ken Liu

Hi, For implementing coming features and optimization, there would be couples of adjustment patches coming, this is the first one (the number looks good): https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/8000 The idea is to get these patches to come in first so that we can have more time before the next release to fix spotted issues. Please help to review the patches and provide different thinking if you have. Thanks. /Ken

Re: [TF-M] [RFC] Static linker scripts for level 1 and 2 isolation

by Ken Liu

Hi, I have merged these patches so they took place now. For lv1 and lv2 users, they don’t need the linker script template any more. The next step is syncing lv3 with lv1/lv2. This change may miss verification on some platforms, please report the build & run issue if you have, thanks. BR /Ken -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Ken Liu via TF-M Sent: Thursday, January 14, 2021 9:49 AM To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] [RFC] Static linker scripts for level 1 and 2 isolation I think the link needs to be updated into: https://review.trustedfirmware.org/q/topic:%22static_linker_scripts%22+(sta… This would make the components arrangement more simpler than using a templating. But for level 3 we still have to using a templating as now there is no 'foreach' like functionalities supported in the ld/sct/icf. /Ken -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Raef Coles via TF-M Sent: Wednesday, January 13, 2021 11:44 PM To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: [TF-M] [RFC] Static linker scripts for level 1 and 2 isolation Hi everyone I'd like to request comments on an upcoming change to the linker scripts. Because of some recent changes to the memory layout for level 1 and level 2 isolation, it's now possible to avoid the generation step via tfm_parse_manifest_lists.py for those linker files. This means that the files are static and have been committed into the source tree (as they used to be). We anticipate this change will make integrating TF-M into non-cmake buildsystems easier, as it will avoid one of the places where files need to be generated at build-time. The reason this is an RFC is that it is a potentially breaking change, but only for integrators _not_ using the cmake buildsystem. Currently the linker uses a large variety of pattern matches to organise the partition symbols, with these patterns being defined in the tfm_manifest_list.yaml. After this change, the linker will only look for two patterns: `*app_rot_partition*` and `*psa_rot_partition*` With the intention that the secure partitions will be compiled into a static library, where the filename is (for example) `libtfm_psa_rot_partition_crypto.a`. The cmake buildsystem will be updated to generate these filenames, but other integrators will need to adjust their compilation steps else the linking will fail. Any comments or concerns would be appreciated. Patches can be found at: https://review.trustedfirmware.org/q/topic:%23static_linker_scripts%22 Raef -- TF-M mailing list TF-M(a)lists.trustedfirmware.org https://lists.trustedfirmware.org/mailman/listinfo/tf-m -- TF-M mailing list TF-M(a)lists.trustedfirmware.org https://lists.trustedfirmware.org/mailman/listinfo/tf-m

Re: [TF-M] Musca-A platform deprecation announcement

by Thomas Törnblom

Hi Anton, The Musca-A is my first choice for testing new things with TF-M, mainly because that’s the simplest Arm board I have access to. What alternative do you recommend? Cheers, Thomas 18 jan. 2021 kl. 18:01 skrev Anton Komlev via TF-M <tf-m(a)lists.trustedfirmware.org>: Hello, I would like to propose the deprecation of Musca-A platform. With whole respect to the first HW platform supported TF-M, it became quite old and difficult to access. The current plan is to remove Musca-A from support and TF-M master code in the next release v1.3.0. Please reply to this mail until Feb 16 (in 4 weeks) having any objection for deprecation. Thanks and Best regards Anton Komlev -- TF-M mailing list TF-M(a)lists.trustedfirmware.org https://lists.trustedfirmware.org/mailman/listinfo/tf-m

Arm Firmware Framework for M 1.1 Extensions Alpha specification

by Andrew Thoelke

Hi all, The PSA Firmware Framework for M 1.1 Extensions specification is now published on Arm Developer. This document introduces a set of updates and extensions to the Arm® Platform Security Architecture Firmware Framework (FF-M) specification, designed to build on the capabilities provided in version 1.0. This is an initial ALPHA release in order to enable wider review and feedback on the changes proposed to be included in the v1.1 specification. At this quality level, the changes and interfaces defined are not stable enough for product development. When the proposed extensions are sufficiently stable to be classed as Beta, they will be integrated into the FF-M version 1.1 specification. The 1.1 Extensions document can be downloaded from: https://developer.arm.com/documentation/aes0039/latest Both the 1.0 Specification and the 1.1 Extensions document are linked from the main PSA architecture page: https://developer.arm.com/architectures/security-architectures/platform-sec… Ken and I have presented a number of times at last year's Tech Forums on the proposals in the specification, most recently I provided a summary of the whole document on 10th December 2020. If you have any feedback, please provide it to arm.psa-feedback(a)arm.com, or discuss the proposals here in the TF-M mailing list. Regards, Andrew
