@section mbedtls mbedTLS for MCUXpresso SDK
  The current version of mbedTLS is based on mbedTLS 2.16.2 released 2019-06-11
   
  - 2.16.2_rev2
    - Bug fixes:
      - Add support for HASHCRYPT context switch check, Hashcrypt without context switch is not able to calculate SHA in parallel with AES.
		HW acceleration of SHA is disabled by default in MbedTLS integration, enabled on chip with context switch. 
	  	  
  - 2.16.2_rev1
    - Bug fixes:
      - Add support for CTR_DRBG using AES-128 for crypto engines without AES-256 capability.
  
 - 2.16.2
    - New features:
      - Ported mbedTLS 2.16.2 to SDK.
      
 - 2.13.1_rev5
    - Bug fixes:
      - ecp_alt_ksdk.c fix CASPER port for ECJPAKE shortcut when points equal 1. This case is point addition and this shortcut
        follows original mbedtls_ecp_muladd() implementation which is required for ecjpake_ecp_add3().

 - 2.13.1_rev4
    - New features:
      - Added support for NIST P-384 elliptic curve with CASPER driver.

 - 2.13.1_rev3

    - Bug fixes:
      - Disable default HW acceleration of SHA in parallel with AES.

    - Bug fixes:
      - Fixed incorrect macro check when skipping AES-192 or AES-256
  
 - 2.13.1
    - New features:
      - Ported mbedTLS 2.13.1 to KSDK.

 - 2.6.0_rev2
   - Bug fixes:
      - ssl_cookie.c now uses SHA256 for COOKIE_MD (instead of original SHA224). Some hw crypto acceleration (such as CAU3) don't support SHA224
        but all support SHA256.
 
 - 2.6.0_rev1
    - Bug fixes:
      - ksdk_mbedtls.c bignum functions now read sign of input mbedtls_mpi at beginning of functions to properly support in place computations
        (when output bignum is the same as one of input bignums). Affected functions: mbedtls_mpi_mul_mpi(), mbedtls_mpi_mod_mpi(), ecp_mul_comb().

    - New features:
      - Ported mbedTLS 2.6.0 to KSDK.
