mbedtls: GCM implementation is replaced with CTR-based calculation
- GCM operation in mbedtls used ECB, which calculated only 16 bytes of data each time. - Therefore, when processing a large amount of data, it is necessary to frequently set hardware acceleration calculations, - which could not make good use of the AES DMA function to improve efficiency. - Hence, GCM implementation is replaced with CTR-based calculation which utilizes AES DMA to improve efficiency.
