History

Torsten Rasmussen 5888428541 mbedtls: kconfig: created MBEDTLS_PROMPTLESS and CUSTOM_MBEDTLS_CFG_FILE Introducing MBEDTLS_PROMPTLESS and CUSTOM_MBEDTLS_CFG_FILE settings. The MBEDTLS_PROMPTLESS can be set to true whenever configuration of mbedTLS is done from a subsystem or module. Such an example is OpenThread, which selects mbedTLS for some predefined crypto settings using OPENTHREAD_MBEDTLS=y. Unfortunately, extensive use of select can easily cause stuck symbol syndrome making it harder than neccesarry for users to later reconfigure as they easily get stuck in incompatible configurations. Providing a MBEDTLS_PROMPTLESS allows such configurations to disable the MBEDTLS prompt itself when selected but avoid stuck symbol if user select another security configuration. Similar with CUSTOM_MBEDTLS_CFG_FILE which ensures that user must explicitly select this symbol before providing a custom mbedTLS config file. Today, other parts the Kconfig tree may set a default value for MBEDTLS_CFG_FILE but that value is stuck and thus changed Kconfig selections elsewhere in the tree will not adjust the value. Introducing CUSTOM_MBEDTLS_CFG_FILE ensures it is known when the user has provided the value.
