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.

Best Regards
