Hi Zhilei,
Besides the info Anton provided that the tech forum is a good place to get closer to the project, this doc introduces the code structure:
And it describes:
cmsis_psa/* - CMSIS implementation for PSA-FF-M SPM.
cmsis_func/* - The library model implementation.
And I admit some of the docs especially the technical ones are out of date, we are under an technical document updating procedure now:
Welcome to tell us what kinds of docs you are expecting and we will put them into the update proposals and discuss how to address them.
BR.

Subject: [TF-M] TF-M design documents about spm
Dear All,
I view the tf-m source code for the first time, and many of the code details can not be make clear. So ..,
where may I find the design documents of spm, for example: trusted-firmware-m-TF-Mv1.5.0\secure_fw\spm\cmsis_func and cmsis_psa software modules.
