Arm Trusted Firmware-M updated to v1.6.0
Added Migration guide for 4.0 FreeRTOS updates
Added drivers for SCE5_B to support hardware acceleration for crypto operations
Updated FreeRTOS
- Secure sockets has been removed. There is no direct replacement.
  - Cellular and FreeRTOS+TCP still have basic socket APIs (no TLS). WiFi has no "public" socket APIs any longer.
- AWS MQTT/HTTP Client modules which were marked as deprecated have been completely removed.
- CoreMQTT and CoreHTTP are still supported. These modules now use the same transport interface that cellular uses for WiFi and TCP as well. There are sockets wrappers for FreeRTOS+TCP, WiFi, and Cellular that tie in to this transport interface.
  - When upgrading existing user projects CoreMQTT/HTTP modules on the stack will show as (Deprecated). The user should go into new stack and add new CoreMQTT/HTTP stacks and then migrate settings from the old ones. This will be described in greater detail in a project migration guide.
- C_SDK and IoT modules are no longer supported. These modules remain in FSP packs for backwards compatibility but they will not compile and no longer bring in source files.
  - In e2 studio these modules will show as (No Longer Supported) with a permanent constraint error and the module info link in the stack will point to a migration guide.
- The MbedTLS/PKCS11 transport interface only supports secure TLS TCP connections over IPV4. IPV6 is not supported. UDP is not supported. Unsecure/non-TLS is not supported.
- As mentioned above WiFi doesn't expose a fully featured sockets API any longer. Customers can potentially use the transport interface or sockets wrapper directly if they need standalone sockets. This comes with the same limitations as mentioned above (only IPv4/TCP sockets).
  - This means there is no way to create a UDP socket with WiFi using an AWS offering.
- The deprecated module AWS PKCS11 PAL (rm_aws_pkcs11_pal) has been removed. Any customer still using this will need to start using AWS PKCS11 PAL on LittleFS (rm_aws_pkcs11_pal_littlefs) instead.
- Dev Assist and examples for CoreMQTT/HTTP have been updated to reflect any changes. Please see these for appropriate code changes.
Secure User-key installation support added via the new SCE Key Installation module

Improvements
