Re: [TF-M] Updated support for IAR toolchain, T398/T413

by Ken Liu (Arm Technology China)

Hi Thomas, If the topic is quite same, you can re-use the existing item. In other case please create a new one. If the existing item is resolved, you can re-open it with some comments (The history will show the status change of this task, keep same topic in one task makes an easy tracking).

Re: [TF-M] Rust implementation of the Armv8-M Security Extension

by Hugues De Valon

Hi Nicolas, Thanks for your mail. From the four LLVM patches needed described in [1], the first one (L1) has landed upstream [2]. Regarding the other ones and your other questions, we are waiting for more information and we will keep you updated as soon as possible.

What is the status of this upstreaming process, are there any road blocks, and is there any ETA on public availability?

adding an option to run code from RAM

by Andrei Narkevitch

Hello, I'm proposing to add an option to support code execution from device RAM. Basically, it comes to defining a new TFM_RAM_CODE SRAM region in gcc and clang linker scripts for code with .*_ramfunc attribute. This region is intended for privileged secure code running from SRAM. With this, whenever you define an attribute e.g. my_ramfunc, this function will be placed into SRAM instead of Flash. An example: _attribute__((section("my_ramfunc"))) void my_function(void) {}; Implementation: https://review.trustedfirmware.org/c/trusted-firmware-m/+/1815 thanks, Andrei This message and any attachments may contain confidential information from Cypress or its subsidiaries. If it has been received in error, please advise the sender and immediately delete this message.

Removing legacy veneer support from TF-M library model

by Mate Toth-Pal

Hi All, I'm planning to remove the custom veneer support for Library model from TF-M. Please see the proposed patch here: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1597/ Ticket for the change is: https://developer.trustedfirmware.org/T439 After this change all secure services must use the automatically generated veneer functions in 'interface/include/tfm_veneers.h', as it is described in the design: https://developer.trustedfirmware.org/w/tf_m/design/uniform_secure_service_… This change doesn't affect the NSPM secure functions ('TZ_.*()' and 'tfm_register_client_id()' ). This change also doesn't affect IPC model at all (i.e. psa api functions). Regards, Mate
