TF-A support for mbedtls3.x has been overdue by number of releases. As per mbedtls support it was advised to use latest and greatest mbedtls-3.3. But mbedtls-3.x breaks API compatibility with mbedtls-2.x To maintain comptability for mbedtls-2.x and enable mbedtls-3.x support add a functionality into makefile to determine the major version of mbedtls and use that to selective include or compile files that are present. With mbedtls-3.x numerous other config changes have been done. Some of the config options deprecated or enabled by default. Thus we decided to introduce a new 3.x config file part of this change for building TF-A with mbedtls-3.3. For futher information on migrating to mbedtls 3.x refer to: https://github.com/Mbed-TLS/mbedtls/blob/development/docs/3.0-migration-guide.md Change-Id: Ia8106d6f526809df927d608db27fe149623258ed Signed-off-by: Govindraj Raja <govindraj.raja@arm.com>
