[PATCH v3 0/5] add the support of sha256_hmac and sha256_hkdf

[Philippe Reynes]

This serie adds the support of sha256_hmac and sha256_hkdf.
A first version was sent several months ago just before the 
integration of mbedtls. This new version is based on mbedtls.

The first patch of this serie add the support of hkdf
using mbedtls.

v3:
- also define sha256_hmac for legacy sha256
- add some #if to define function only when needed

Philippe Reynes (5):
  mbedtls: enable support of hkdf
  lib: sha256: add feature sha256_hmac
  test: lib: add test for sha256_hmac
  lib: mbedtls: sha256: add support of key derivation
  test: lib: add test for key derivation
