Previously, TF-A could not support large RSA key sizes as the configuration options passed to MBEDTLS prevented storing and performing calculations with the larger, higher-precision numbers required. With these changes to the arguments passed to MBEDTLS, TF-A now supports using 3072 (3K) and 4096 (4K) keys in certificates.
