[PATCH v2 00/19] Add ECDSA support for FIT image verification

[Sascha Hauer <s.hauer@pengutronix.de>]

This series implements ECDSA signature verification for FIT images.
The ECDSA code itself is taken from the Kernel. Currently only supported
way to specify a ECDSA key is to compile it into the binary using
CONFIG_CRYPTO_ECDSA_KEY, taking it from a device tree is not ye
supported.

Changes since v1:
- better split up rsatoc patches
- keep engine support around in rsatoc as it is still needed in many
  cases
- Add more cleanup to rsatoc

Sascha Hauer (19):
  errno: include string for EOPNOTSUPP
  rsatoc: disable deprecated function warnings
  rsatoc: remove unnecessary function call
  rsatoc: pass EVP_PKEY around
  rsatoc: rename rsa_err() to openssl_error()
  rsatoc: move engine initialization to engine_get_pub_key()
  rsatoc: cleanup error handling
  rsatoc: remove unnecessary error check
  rsatoc: use non deprecated openssl functions to retrieve RSA params
  rsatoc: check error value of gen_key()
  rsatoc: rename to keytoc
  keytoc: add ecdsa support
  keytoc: Let openssl_error() take a format string
  keytoc: clarify error messages
  malloc: implement free_sensitive()
  Add elliptic curve cryptography (ECC) helper functions
  crypto: add ECDSA support
  crypto: make RSA a visible option
  fit: Add ecdsa support
