 #############################################################
 
 The Nordic Secure Partition Manager (SPM) was replaced with Trusted Firmware-M (TF-M) as the default trusted execution solution in the |NCS| v2.1.0.
-This change was made to enhance the security features of the SDK by integrating the more widely adopted TF-M that aligns with the Arm Platform Security Architecture (PSA).

+Migration from SPM to TF-M requires changes in the application code and the partition configuration.
 The interface to TF-M is different from the interface to SPM.
 Due to that, the application code that uses the SPM Secure Services needs to be ported to use TF-M instead.
