[PATCH v4 0/3] i.MX6: CAAM engine support

[Steffen Trumtrar]

Hi!

This series adds basic support for the i.MX6
Cryptographic Acceleration and Assurance Module (CAAM).

The CAAM supports multiple hashing/encryption engines,
this series only supports the included hardware random
number generator.

Changes since v3:

  - remove jobring config option
    - the CAAM driver doesn't do anything useful without
      them anyway, so always build the jr.c and probe the
      subdevices in ctrl.c instead of just registering the
      devices.
  - probe the RNG in ctrl.c
    - the RNG is a subdevice of the CAAM. Call the
      probe function manually if driver is enabled.
  - merge old patch 4/5 into new 3/3
  - get rid of superfluous old patch 5/5

Tested with a riotboard.

Regards,
Steffen
