@adbridge: The impact of disabling this is a potential decrease in performance and possibly an increase in code size, etc in targets that are using this acceleration code as disabling it just means that we will be using the default mbed TLS software implementation. Of course, this PR is only a workaround and I am currently working with @adustm to assess the full impact of the issue in #5079 and #4928.
