[RFC] Moving partition stack into partition BSS/ZI.

by Ken Liu

Hi, We are now allocating partition's stack inside linker script file, and there are two external patches trying to move these stack definitions into partition's BSS/ZI: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5374/5 https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/6508/1 The advantages: - Simplify the linker script/sct templating, stack items can be saved. - Stack as global just uses 8 bytes alignment instead of wider bytes alignment (such as 32 bytes in most of the cases). - Stack is private data, putting private data together is a direct way. And the disadvantages: - Stack memory and global memory may affect each other - actually we don't apply such protecting mechanism now? Anything I missed? Any feedbacks are welcome. We would collect your feedbacks and update the patches if they are still available after your comments. Other proposals are welcome, too. Thanks. /Ken

[RFC] Build: Move UART symbols to SPRTL

by Kevin Peng

Hi Platform owners, explicitly ST, Nordic and NXP owners. Could you confirm that this patch<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/6678> wouldn't break your platforms. The patch changes the build system to put the UART drivers to the SPRTL. It is important to improve the isolation implementations. For more details, please see the patch. We will wait for one more week and merge it as is if no feedbacks. Any feedbacks from others are welcome always. Best Regards, Kevin

Re: [TF-M] Secure Enclave solution in TF-M

by Mark Horvath

Dear All, I would like to merge the Secure Enclave topic at about middle of next week, feel free to give any feedback. https://review.trustedfirmware.org/q/topic:%22Secure+Enclave%22+(status:ope… Best regards, Mark From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Mark Horvath via TF-M Sent: 14 September 2020 21:00 To: 'tf-m(a)lists.trustedfirmware.org' <tf-m(a)lists.trustedfirmware.org> Subject: [TF-M] Secure Enclave solution in TF-M Dear All, Following the tech forum presentation (back in 6th August) I uploaded the draft design document for the Secure Enclave topic: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5653 I also updated the first implementation of the proposed solution for the Musca-B1 board with minimal features, marked as WIP: https://review.trustedfirmware.org/q/topic:%22Secure+Enclave%22+(status:ope… Limitations, missing features, notes: * No support for isolation level2 on SSE-200 * Protected Storage is an Application RoT partition, but PS also moved to Secure Enclave * Some regression tests running on secure side of SSE-200 fail as all messages are forwarded with the same client ID to Secure Enclave * All IPC message forwarding is a blocking call * Only one message is put into the mailbox at a time * Musca-B1 related documentation is not complete yet * Generated files are not committed, manifest parser should be run before build. * The BL0 component mentioned in the tech forum presentation is not uploaded, as it is based on the new cmake system, and not so interesting right now * Cmake changes are rudimentary, will be rebased to new cmake system. Any feedback very welcomed!

Re: [TF-M] Externally override flash layout and pin configurations (out-of-tree platforms?)

by Rønningstad, Øyvind

I've created a proof of concept for allowing out-of-tree platforms here: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/7301 It was simpler than I had thought :) Øyvind From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Ken Liu via TF-M Sent: Thursday, November 26, 2020 07:57 To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] Externally override flash layout and pin configurations (out-of-tree platforms?) Hi, In the ideal case with HAL API, the platform itself can decide which variant's layout to be applied, selected by build system switches or just some header files. Because SPM could get what it needed by HAL API run-time. It can be mostly done inside the platform folder if one platform has the variants management already. Others please give inputs as this is a very useful topic, we can list down the problem we met during integration first. BR /Ken From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org<mailto:tf-m-bounces@lists.trustedfirmware.org>> On Behalf Of Rønningstad, Øyvind via TF-M Sent: Thursday, November 26, 2020 3:47 AM To: tf-m(a)lists.trustedfirmware.org<mailto:tf-m@lists.trustedfirmware.org> Cc: Rasmussen, Torsten <Torsten.Rasmussen(a)nordicsemi.no<mailto:Torsten.Rasmussen@nordicsemi.no>> Subject: [TF-M] Externally override flash layout and pin configurations (out-of-tree platforms?) Hi all In our work integrating TFM into Zephyr and the nRF Connect SDK, it's apparent that the integration would be a lot smoother if we could specify TFM's flash layout externally. Looking into it a bit, I came up with a draft proposal here: https://github.com/zephyrproject-rtos/trusted-firmware-m/pull/18/files<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.co…> We could just modify our own platforms to this and be happy, but I'm wondering if there would be interest in standardizing something. Now, a related problem is: How can we make it easier to add multiple boards based on a single chip. For the Nordic platforms we've already separated the chip-specific code (nRF9160/nRF5340) from the board specific code (DK/PDK), and for the boards, it really boils down to pin configurations. We could allow to specify pins via Cmake instead, to easily allow users to support their production PCBs. But (this was brought up in the above PR) we can also solve both problems by adding support for out-of-tree platforms. For example, allow TFM to be built like so: cmake -DTFM_PLATFORM=../../../../my_custom_board ... This would probably be less work that designing a new interface for overriding flash layouts and pin configurations. What are your thoughts? BR, Øyvind Rønningstad
